python - pythone 3.3.2 age >= 24: TypeError: unorderable types: str() >= int() -

print("how old you") age = input(">") if age >= 24: print("you getting old") print (age) else: print("i don't care") print (age) 

this error getting:

if age >= 24: typeerror: unorderable types:     str() >= int() 

on python 3, input() always returns string value. use int() type convert it:

if int(age) >= 24: 

a string value , int not orderable:

>>> '24' > 23 traceback (most recent call last):   file "<stdin>", line 1, in <module> typeerror: unorderable types: str() > int() 

note int() can throw valueerror exception, if input cannot converted:

>>> int('why want know age?') traceback (most recent call last):   file "<stdin>", line 1, in <module> valueerror: invalid literal int() base 10: 'why want know age?'
