如何在python中过滤'def‘中的数字

import re

def filter_digits_in_def(string):
    # 使用正则表达式匹配'def'后面的数字，并替换为空字符串
    filtered_string = re.sub(r'def\d+', '', string)
    return filtered_string

# 调用函数进行过滤
string = "def1234 function def5678"
filtered_string = filter_digits_in_def(string)
print(filtered_string)

def function def

def filter_digits_in_def(string):
    # 将字符串拆分成单词列表
    words = string.split()
    
    # 过滤掉'def'后面的数字
    filtered_words = [word for word in words if not word.startswith('def') or not word[3:].isdigit()]
    
    # 将过滤后的单词列表重新拼接成字符串
    filtered_string = ' '.join(filtered_words)
    return filtered_string

# 调用函数进行过滤
string = "def1234 function def5678"
filtered_string = filter_digits_in_def(string)
print(filtered_string)
