How to run python program in cmd

Command Prompt provides us all together with a different approach for dealing with our programs. The programs can be executed by accessing the directories.

In this article, we will discuss how we can run python programs in command prompt and what are the various commands we can use that can become a driving force towards our professional growth.

We have already discussed the steps of running a program in Python in previous articles.

Let’s have a quick recall

Running a program in command prompt-

Command Prompt acts as an interpreter in Windows and on specifying the correct path and by using the necessary commands, we can perform the required tasks. Typing 'cmd' in the search area of the taskbar will show the command prompt option and then we can start working on it.

• Open Command Prompt from the taskbar and run your file by specifying the file name.
• Make sure you provide the correct destination of your file.

We will execute the following program-

 a=int(input("Enter 1st number: "))         #obtaining first value
 b=int(input("Enter 2nd number: "))       #obtaining second value
 c=a+b                                                   #performing addition
 print("Sum of a and b is {}".format(c))  #displaying the result 

What exactly we need to do here is we will open a text editor in a system like Notepad and then write this program and save this file with an extension .py

Let us how it can be implemented-

1. Open Notepad in your system and type the following program-

2. Click on File and then click on ‘Save As’. Save your file with the extension .py

3. Open the command prompt and make sure you correctly specify the destination of your file and then type the name of your file to access it.

4. On clicking 'Enter' it will display the output and will ask the user to input the values for the addition of numbers.
5. Once the values are provided, it will produce the desired output.
