我在 python 的 if -else 程序中遇到编译错误。代码是用 Python 3 编写的，谁能帮帮我

Question

  n = int(input().strip())
  if N % 2 != 0:
    print "Weird"
else:
    if N >= 2 and N <= 5:
        print "Not Weird"
    elif N >= 6 and N <= 20:
        print "Weird"
    elif N > 20:
        print "Not Weird"
##if else problem in python 3

Answer 1

from the print statement without paranthesis, it seems the code you are showing is python2, partially compatible with python3.

• Either execute it with python2 interpreter (deprecated)
• Or change a few stuffs to get it compliant to python3.

Besides, as mentionned, the take care of the case sensitivity for symbols like variables and functions.

Answer 2

I think the problem is that you named you variable n. But you use it with a capital N. Python is case-sensitive so you have to keep everything the same.
