Step 1: Click on Run in the Menu bar.
Step 2: Click on Run Module option.
Running a program
The program will execute and the output will be shown in the Shell window.

very useful for testing
a code as it displays
the errors one by one.

Input and Output
Python provides two commonly used functions input() and output() for input and output.
The input() Function
The input() function takes the user’s input while a program executes. The general syntax of
the input() function is as follows:
input([<prompt>])
Here, prompt is the string or message we wish to display on the screen. Example:
name = input("Enter your name: ")
>>> Enter your name: "Mohan"
The print() Function
The print() function prints or sends the output to the standard output device, which is usually
a monitor. This function auto converts the items to strings, i.e., if you try printing a numeric
value, the print() function will automatically convert it into equivalent string and print it. The
print() function also introduces spaces between items automatically.
The general syntax of the print() function is as follows:
print [<expression 1> , <expression 2>...]
For example:
print ("Python is easy").
Let's create a program to use the input( ) and print( ) functions.
