3. Testing Python on Terminal / Command Prompt

In the previous step, we have successfully installed Python in our system and now we have to check if our process was right or not.
For that we will run some python commands in our terminal / command prompt.

• Search CMD on your PC (Windows) and open it.

Searching CMD on Windows	CMD Interface

• So, this is the CMD or Command Prompt interface and we will test the Python here.
• Type python or py and press Enter. C:\Users\saswa>python OR C:\Users\saswa>py

• It will return a result like this
  

  Python 3.9.2 (tags/v3.9.2:1a79785, Feb 19 2021, 13:44:55) [MSC v.1928 64 bit (AMD64)] on win32
  Type "help", "copyright", "credits" or "license" for more information.
  

• So, if you get the output as this, then the Python is successfully installed in your system and is successfully executed.

  • Note that here, Python 3.9.2 is the installed version in my system. It may vary if you have installed other versions. So, don't panic.

• Now let's run some simple Python snippets and test the execution
  

  >>> print("Hello, World!")
  Hello, World!
  >>> print(5+10)
  15
  >>> a=10, b=109
  File "<stdin>", line 1
  a=10, b=109
    ^
  SyntaxError: cannot assign to literal
  >>> a = 10
  >>> b = 201
  >>> print(a+b)
  211
  >>> print("Thank You!")
  Thank You!
  >>>
  

• So all our code snippets are working properly. And hence the installation of Python in our system is successfull now with testing in CMD.
