x = raw_input("write number") if x.isalpha(): print "invalid!" elif x%2==0: print "the number have written even" elif x%2!=0: print "the number have written odd" else: print "invalid!"

it supposed check if number odd or , print out. if statement checks if raw_input alphabet because won't work. , elif statements check odd or even.

the homecoming value of raw_input string. you'll need convert integer if want utilize % operator on it:

x = raw_input("write number") if x.isalpha(): print "invalid!" x = int(x)

instead of x.isalpha() can utilize exception handling instead:

try: x = int(raw_input("write number")) except valueerror: print 'invalid!' else: if x % 2 == 0: print "the number have written even" else: print "the number have written odd"

because int() raise valueerror if input not valid integer.
