In this program we will see how to receive string input from user in Python. using input is unsafe as it evaluates your python code as commands and can cause someone to hack your code. So let’s use it in our below example code. Set in Python is a data structure equivalent to sets in mathematics. For this purpose, Python provides the function input(). While Python provides us with two inbuilt functions to read the input from the keyboard. If you want your code to work on both Python version, use condition by checking its python version. input has an optional parameter, which is the prompt string. Please mail your requirement at hr@javatpoint.com. By default, the input() function takes input as a string so if we need to enter the integer or float type input then the input() function must be type casted. Output: How the input function works in Python : When input() function executes program flow will be stopped until the user has given an input. Python 3.6 uses the input() method. Get String input from user. To check the Python version, open command line (Windows), shell (Mac), or terminal (Linux/Ubuntu) and run python -version. Writing code in comment?
