I'm new to python working on a Raspberry pi. I'm trying to make a number guessing game based on user input.
Code:

num = int(raw_input("Pick a number: "))

While num != 4 :
     int(raw_input("Incorrect, pick again :)) #indented
else :
     print("Good job") #indented
     exit #indented

Error:

Error:
While num != 4 :
           ^ invalid syntax

python is case-sensitive
While is not the same as while
