对带有数字后缀python的重复字符串进行分组

import re

def group_repeated_strings(strings):
    pattern = re.compile(r'(\w+)(\d+)')
    groups = {}
    
    for string in strings:
        match = pattern.match(string)
        if match:
            prefix = match.group(1)
            suffix = match.group(2)
            
            if prefix in groups:
                groups[prefix].append(suffix)
            else:
                groups[prefix] = [suffix]
    
    return groups

strings = ['python1', 'python2', 'java1', 'java2', 'java3', 'csharp1', 'csharp2']
result = group_repeated_strings(strings)
print(result)

{'python': ['1', '2'], 'java': ['1', '2', '3'], 'csharp': ['1', '2']}
