原始输入后，python 2.7名称“ x”未定义错误

Question

My program should take user input of three integers and choose the highest valued odd number.

my code is:

X = int (raw_input ('Enter intenger: '))
y = int (raw_input ( 'Enter intenger: '))
z = int (raw_input ('Enter intenger: '))   
if x > y and x > z and x%2==1 :
    print 'x'
elif y > z and y%2==1:
    print 'y'
elif z >y and z%2==0 :
    print 'z'
else:
    print 'no odd numbers'

after being prompted to enter integers 3 times my error message is:

Traceback (most recent call last):

line 5, in

if x > y and x > z and x%2==1 :

NameError: name 'x' is not defined

I've tried writing:

x = x 

y = y

z = z

and bunch of other ideas as well and am not getting it.

thank you

Answer 1

X = int (raw_input ('Enter intenger: '))您在varialbe声明期间给了X ，但是在使用时使用x

Answer 2

Your issue is simply a typo:

change this:

X = int (raw_input ('Enter intenger: '))

to this:

x = int (raw_input ('Enter intenger: '))

Python variables are case sensitive so X is not the same thing as x
