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

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
• ...

You have to install a package called getkey

from getkey import getkey, key print("press enter") var = getkey() if var == key.ENTER: print("You pressed enter") else: print("You didnt") 

It will only take a one character input though

user_input=input("ENTER SOME POSITIVE INTEGER : ") if((not user_input) or (int(user_input)<=0)): print("ENTER SOME POSITIVE INTEGER GREATER THAN ZERO") #print some info import sys #import sys.exit(0) #exit program ''' #(not user_input) checks if user has pressed enter key without entering # number. #(int(user_input)<=0) checks if user has entered any number less than or #equal to zero.
