Using the if statement

Example 6.1. Using the if statement

#!/usr/bin/python
# Filename: if.py
number = 23
guess = int(raw_input('Enter an integer : '))

if guess == number:
print 'Congratulations, you guessed it.' # New block starts here print "(but you do not win any prizes!)" # New block ends here

elif guess < number:
print 'No, it is a little higher than that' # Another block # You can do whatever you want in a block ...

else:
print 'No, it is a little lower than that' # you must have guess > number to reach here

print 'Done'
# This last statement is always executed, after the if statement is executed

Output

$ python if.py
Enter an integer : 50
No, it is a little lower than that Done
$ python if.py
Enter an integer : 22
No, it is a little higher than that Done
$ python if.py
Enter an integer : 23
Congratulations, you guessed it. (but you do not win any prizes!) Done
