Python代码在一个.py文件中工作,但不是新文件

标签: python terminal palindrome

我使用Ubuntu中的Terminal在.py文件(由Sublime Text v3126生成)中运行以下代码。 Ctrl + B在Sublime Text中不显示任何错误,但在终端中运行会产生错误。奇怪的是,这个代码在以前的.py文件中使用了Terminal,后者有其他代码。无论如何,这是特定的代码:

import math
import cmath
import datetime
import random as RAN
from tabulate import tabulate

def main():
    print ("")
    print("Key in a word.")
    while True:
        try:
            x = str(input())
            x = x.casefold()
            xr = reversed(x)
            print("")
            print("Using iterative and/or recursive functions...")
        except ValueError:
            print("Invalid input. Try again")
            print("")
            continue
        if (list(x) != list(xr)) or (x != x[::-1]):
            print("The input is not a palindrome. Try again.")
            print("")
            continue
        else:
            print("The input is a palindrome.")
            break

if __name__ == '__main__':
    main()

因此,当我在仅包含此代码的.py文件中运行此代码时,我在终端中收到此错误:

Key in a word.
example
Traceback (most recent call last):
  File "./Test Pad.py", line 30 in <module>
    main()
  File "./Test Pad.py", line 12 in main
    x = str(input())
  File "<string>", line 1, in <module>
NameError: name 'example' is not defined 

感谢您的考虑。
