How To Install Python 3 on Windows 10

If you are considering becoming a Python developer, the first thing you should be able to do is update your Python version installed on your computer. Python can easily be installed on your computer in a number of ways, but we are going to demonstrate the fastest and most reliable installation method today.

We will be taking the support of the Npn package manager to install the Python 3 version in Windows 10. Also, we are only defining the method to install Python 3 in Windows 10, so if you are using Windows 8 or some other version of Windows, some of the steps might be different, so be careful and read the instructions written below carefully.

What Is Python?

Python is one of the most common programming languages which is both interpreted and object-oriented. The programming language was developed by Guido van Rossum, and the first official release dates back to February 20, 1991. One of the things which makes the Python language so unique is that it was developed by just one person. Usually, what happens is, some like-minded developers come together to create a new programming language, but that was not the case with Python.

In addition to this, Python doesn’t have any copyright. The result is that it is widely used by so many people, despite the constant updates to the programming language. We give you a few reasons why Python can enhance the features of your project and make it easier to develop it.

  • First of all, Python is quite simple and easy to learn; its syntax is quite like the English language, and what you type as a code can be understood by even a layman who has some basic knowledge of programming.
  • Likewise, when it comes to teaching the programming language, a teacher doesn’t have to put a lot of effort into explaining the working of the syntax and can focus on general programming techniques which a student will be using in their project. There are no strange exceptions that a student needs to remember; neither are their exotic tricks to remember when developing Python.
  • With the help of Python, you will be able to develop new software in a shorter time.
  • Lastly, Python is free to use, and it can handle multi-platform dependencies with ease, which is something a lot of programming languages are missing or require developers to download extra packages to support this functionality.

10 Reasons Why You Need To Download The Latest Version of Python 3 In Windows 10?

There are tons of new features which you will be missing if you are not installing the latest version of Python, which is Python 3. Below we have written some of the advantages of using Python 3 over Python 2 and how the newer version makes developing software easier for you.

1. In Python 3 Print Works As Function

Print used to be a statement in Python 2, but now in Python 3, you get to use the same keyword, which is “print,” but it will work as a function, not a statement. This makes printing lines in Python 3 much more effortless.

2. Mathematics Is Now Relatable

In Python 2, when you divide numbers, a value that is less than 0 will be displayed as “0”. In the case of complex mathematical answers where a user needs to calculate the three to four decimal places, Python 2 programming is useless because it does not have a decimal value. Python 3 changed this; now, dividing 2 by 1 will result in 0.5 in float. In case you are looking for a way to use the truncating behavior, please use “//” instead of /.

3. Comparisons Are Meaningful

The recurring problem with Python 2 was its inability to compare two things properly. Even if you write a silly code that doesn’t really make any sense, the program will run, and the outcomes will remain the same, even though you change the input. But in Python 3, you cannot perform wrong comparison operations. When your comparison code doesn’t make sense, you will get the output TypeError. With this, Python 3 has added an extra layer of robustness in its code writing.

4. No Need Of Xrange()

If you have worked on Python 2, you know Xrange has the advantage of being faster than range when you are iterating. But if you look at Python 3’s implementation, you will see that both range and xrange works precisely the same. Thus, there is no xrange in Python 3. If you do type in xrange in your code, it will again show you the TypeError as an output.

5. Better Iterable Unpacking

With the code written in Python 3, your code will have the advanced level of iterable unpacking. Thus, we can perform a number of operations that can’t take place in Python 2.

6. One Text Input

In Python 2, there are two text inputs present, and these inputsare str and Unicode. If we look at the str type in Python 2, it only takes the input that is written as ASCII characters. Also, Python 2 has a one-byte type known as bytearray. But if we compare this with Python 3, we only get one text type, which is quite similar to the Unicode text type in Python 2. One more thing you need to know is that in Python 3, str is the only text type, which can work with Unicode by default.

7. No More Inequality Operator Error

When we are working on Python 2, both != and <> operators can be used as inequality operators. But when you are using them in Python 3, only one of them works, and it is !=. So now developers will have less confusion about which inequality operator to choose when writing the code.

8. There Is No raw_input ()

We use raw input() in Python 2 to input the data as a string; the simple input() is used to read and store the data type. But with the use of raw_input(), a developer has to be careful of adding quotations. If they are missing from the code, it can perform malicious behavior and will not provide the required output which you are looking for. With Python 3, there is only one input method, and that is input(), and when you type this in your code, it will store the input as a string no matter the data type of the input.

9. Use Of Iterables In Place Of List

With Python 3, you are always getting the output in the form of iterables when the inputs are in the range, zip, map, and filter format. By contrast, with the latest Python 3 version, dictionary methods such as keys (), values (), and more will produce views instead of a list of results.

10. Handling Exceptions

One of the biggest improvements in Python 3 from Python 2 is how it handles the exception. With Python 2, you will miss out on the exception, and there is no way to trace back. But in Python 3, all the exceptions can be seen, which gives users a better overview of all the exceptions present in their code.

Difference Between Python 2 and Python 3

We have given below the differences between Python 3 and Python 2. These differences will make it easier for you to make a decision whether you need to use Python 2 or move towards a newer version which is Python 3.

Python 2 Python 3
The Python 2 was released in the year 2000 Python 3 was officially released in 2008.
Syntax of Python 2 doesn’t require the user to enter parentheses to print. Thus, to output hello, you need to write the following code in Python 2: print “hello.” In order to print a simple function like hello, you need to use parentheses like print (“hello”).
With Python 2, when you are dividing two integers, you are always going to get an integer value.

In order to get a Unicode string stored in Python 2, you must define the string like this “a.”

When you divide two integers in Python 3, you will get a float value as the output.

By default, in Python 3, the Unicode is stored in the form of strings.

From the above two examples, we can clearly see that writing Python 2 syntax is a bit difficult, and the same goes for understanding it. With the latest version of Python 3, you will have a much simpler syntax to write the code.
When it comes to defining the rules of comparison in Python 2, you need to write complex code. The rules for ordering the comparison on Python 3 are more simplified.
The xrange() in Python 2 are written in codes to define the iterations. In order to perform the iteration in Python 3, a new range () function has been introduced.
Exceptions have to be present in enclosed notations. Also, the exceptions have to be present in closed parentheses.
When global variables are defined and used inside a for-loop, their values will be changed. There are no difficulties in importing the packages and the code written in Python 3, but some packages might not work correctly, and you need to find their alternatives.
Lastly, many older packages and libraries created for Python 2 are not forward compatible. Consequently, if you use them in your project, they won’t work on systems with a newer version of Python. There are also a number of developers who are creating libraries for Python 3, so there are tons of packages and libraries available for use during the development of the project.

Steps To Install Python 3 In Windows 10

Step – 1: Check The Version Of Python

First, you need to check the version of Python already installed in your OS. For this, you need to go to PowerShell or launch the command prompt. Once you launch one of these two applications, you need to type in the command:

C:\> python –version

To find where the Python is installed in your system, write the following command:

C:\> where.exe python

Step – 2: Find the Options Available To Download Python 3

Now that you have seen the version in your operating system, you know whether you need to update it or not. If you want to update to a newer version, you first need to download the official Python.exe installer.

Open the web browser that you prefer and go to the official Python website. After that, go to downloads for Windows, look for the Python version that you want to install, and select the link to download its executable.

Step -3: Installing Python 3 From Python Executable Installer

Once the executable installer is downloaded, launch the installer and add the path where you want to install the latest version of Python. After that, click on Install Now with all the recommended settings. With all the latest versions of Python 3, you will be getting Pip manager and IDLE by default with the installation. But for the older versions, you might need to install them separately.

When installing Python 3 using an executable installer, you will see a dialog prompt that will ask you to disable the path length limit. If you choose this option, you will allow Python 3 to bypass its 260-character MAX_PATH limit. This will help Python to use long path names.

Step – 4: Check If The Latest Version Has Installed

Once the installation is complete, you need to go to the command prompt and type in the following command to see if the update has been successful or not.

C:\> python –version

Another method to find out whether you have successfully installed the latest version is by opening up the path where you have installed the Python and locate the python.exe file. Double click on it, and it will open the command prompt, which shows the output of the current version installed on your computer.

Step – 5: Install Pip (Optional)

As we said earlier, the latest version of Python will include Pip manager, but if you are installing the older version, you need to download and install it separately. You need to perform this step if you have more than one Python version available on your computer and Pip is not installed by default.

To Install Pip, launch the command prompt and type in the following command:

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

After that, you have successfully downloaded the Pip in your system. Now you have to install it in Python. To install the Pip, use the following command:

python get-pip.py

Your command prompt will show that it is installing the pip manager and once it’s done, it will show the output Successfully installed pip “version” wheel “version.”

To verify if the Pip is installed in your system, type pip help in your command prompt, and if the installation is successful, it will show you a list of commands that you can use with Pip and the path where the Pip is installed in your system.

Wrapping Up

So this is how you install Python 3 in your Windows 10 operating system. You can install it via command prompt, but that method is quite tedious and will require you to have prior knowledge of using Command prompt thoroughly. If your Python 3 version doesn’t come with Pip and wheel, it is recommended to download them separately as you will need them when working on multiple projects and different versions of Python packages.
