what is input function in python

The input() function in Python is used to take input from the user. When called, it prompts the user to enter some data, and whatever is entered is always returned as a string.

Key points about input() function:

• Syntax: input(prompt)
• Parameter: An optional string prompt that is displayed to the user before taking the input.
• Return value: It always returns the input as a string.
• You can convert the returned string to other data types like integer or float using functions like int() or float() if needed.

Examples:

1. Basic use to take input and print it:

   python
   
   userInput = input("Enter something: ")
   print(userInput)
   

2. Taking numerical input by converting the string to int:

   python
   
   number = int(input("Type an integer: "))
   print(number + 7)
   

3. Taking float input by converting the string to float:

   python
   
   number = float(input("Type a number: "))
   print(number + 7)
