我有一個字符串'Dogs are highly5 variable12 in1 height and weight. 123'我想得到'Dogs are highly variable in height and weight. 123'我怎樣才能做到這一點？這是我現有的代碼：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'

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