How to know if a user has pressed the Enter key using Python

Question

How to know if a user has pressed Enter using Python ?

For example :

user = raw_input("type in enter")
if user == "enter":
    print "you pressed enter"
else:
    print "you haven't pressed enter"

As @jonrsharpe said, the only way to exit properly the input function is by pressing enter. So a solution would be to check if the result contains something or not:

text = input("type in enter")  # or raw_input in python2
if text == "":
    print("you pressed enter")
else:
    print("you typed some text before pressing enter")

The only other ways I see to quit the input function would throw an exception such as:

• EOFError if you type ^D
• KeyboardInterrupt if you type ^C
• ...
