How to install python in windows?

Now let’s check what is the exact python version installed in my system. To check that I entered the below command

python --version

But unfortunately, I got the below error

Traceback (most recent call last):
File “<stdin>”, line 1, in <module>
NameError: name ‘python’ is not defined

Python download and installation

Now why this error?

Actually, We are trying to start the Python interpreter by running the command “python”.

However the interpreter is already started. It is interpreting python as a name of a variable, and that name is not defined here so it is showing “name python is not defined”.

But don’t worry python is installed correctly. To verify that, what I did is I entered print(“pythonguides”) and I got the expected output as “pythonguides”.

Install python in windows 7

Now in two ways we can see the python version in this case

1- Please enter the below line of codes in the python terminal

import sys
 
mypythonversion = 0x600
mypythonversion = sys.version[:5]
print("%s%s" %("my python version is: ", mypythonversion))

Now see the below screen shot, It is showing my python version is “python 3.8.2”.

2- The other approach here to see the python version is to open the system command prompt and enter the below command. You can see the it will display the version is Python 3.8.2.

python --version

Now we are don with the installation of python 3 in different operating systems. So the next that we need to start the development activities is we need to install one IDE or code editor where we will write and execute our code.

Python IDEs and Code Editors

We will discuss about the different python IDEs and code editors needed for the development of python.

What are IDEs and Code Editors?

When we start working with any of the programming languages, We need some tools or editors where we need to write and execute our programs.

IDE is nothing but an “Integrated Development Environment”. This is a software that is designed for software development. This tool helps to write, design, debug the code easily.

When you are getting an error you can put a debugger and check line by line where the issue is from. Not only this much, An IDE will highlight the code and has auto-suggestion features etc.

Where as the code editors are simple text editors which can highlight the code syntax as well as can format your code easily.

There are few good code editors that can support the debugging as well.

If you are using python for a normal programming purpose then you can choose a good code editor instead of going for an IDE. But if you are building any complex project using python then IDE is the best choice.

There are many IDEs and code editors are available in the market. Some are for general purpose and supports many languages and few you can only use for python development.

1- PyCharm:

Pycharm is one of the best development IDE for python.

This IDE has lots of good features like Code editor, Error highlighting capability, Code debugging capability,supports source controls as well.

Pycharm is  available in both paid (Professional) and free open-source (Community) editions.

This is one of the simple IDE and supports in Windows,Linux and Mac platforms.

Let’s discuss the steps to install pycharm community version 2020.1 which is free in Windows 10.

Step-1:

Download the Pycharm executable file from the official site. Click on the “Download” button under the community option.
