isalpha python 函数不会考虑空格 [英] isalpha python function won't consider spaces

问题描述

所以下面的代码接受一个输入并确保输入由字母而不是数字组成.如果输入包含空格，我将如何使其也打印原始

So the code below takes an input and makes sure the input consists of letters and not numbers. How would i make it also print orginal if the input contains a space

original = raw_input("Type the name of the application: ")

if original.isalpha() and len(original) > 0:
    print original
else:
    print "empty"

尝试了此代码，但在输入也是数字时也能工作.

tried this code but worked when the input was a number too.

original = raw_input("Type the word you want to change: ")

if original.isalpha() or len(original) > 0:
    print original
else:
    print "empty"

推荐答案

看起来字符串就是这样工作的.

It looks like that's just how string works.

两个选项:

if all(x.isalpha() or x.isspace() for x in original):

(根据以下InspectorG4dget的建议修改)

或

original.replace(' ','').isalpha()

应该可以.
