删除附加到单词的所有数字 - Python

Question

我有一个字符串'Dogs are highly5 variable12 in1 height and weight. 123'我想得到'Dogs are highly variable in height and weight. 123'我怎样才能做到这一点？这是我现有的代码：somestr = 'Dogs are highly5 variable12 in1 height and weight. 123'for i, char in enumerate(somestr):    if char.isdigit():        somestr = somestr[:i] + somestr[(i+1):]但它返回'Dogs are highly variable1 n1 hight and weight. 123'

Answer 1

给定

import string

s = "Here is a state0ment with2 3digits I want to remove, except this 1."

代码

def remove_alphanums(s):

    """Yield words without attached digits."""

    for word in s.split():

        if word.strip(string.punctuation).isdigit():

            yield word

        else:

            yield "".join(char for char in word if not char.isdigit())

演示

" ".join(remove_alphanums(s))

# 'Here is a statement with digits I want to remove, except this 1.'

我们使用生成器生成独立的数字（带或不带标点符号）或通过生成器表达式过滤单词。
