User Input
Python 3.6 uses the input() method.
Python 2.7 uses the raw_input() method
Example:
1 #!/usr/bin/env python3
2
3 def main():
4 username = input("Enter username:")
5 print("Username is: " + username)
6
7
8 if __name__ == "__main__":
9 main()
Note
Python stops executing when it comes to the input() function, and continues when the user has given some input.
