Python input () is a built-in function that reads a line from input, converts it to a string (stripping a trailing newline), and returns that. Input can be from different sources but most often the input is from the keyboard. The flow of the program is stopped when input () function is called until the user has given the input ending with return key.
Python is simpler and more consistent-and many Python enthusiasts or folks who have had a god experience with the language will attest to that. The fact that Python uses key words makes things easier especially for beginners and because of it, the learning process is cumulatively shorter and fun.
