python字符个数统计

python统计输入字符串中大写字母，小写字母，数字字符及其他字符个数 想问下应该怎样写

import re

def count_chars(string):
    counts = {'uppercase': 0, 'lowercase': 0, 'digit': 0, 'other': 0}
    for char in string:
        if char.isupper():
            counts['uppercase'] += 1
        elif char.islower():
            counts['lowercase'] += 1
        elif char.isdigit():
            counts['digit'] += 1
        else:
            counts['other'] += 1
    return counts

def count_chars_regex(string):
    pattern = r'[A-Z]|[a-z]|\d'
    counts = {'uppercase': 0, 'lowercase': 0, 'digit': 0, 'other': 0}
    for char in re.findall(pattern, string):
        if char.isupper():
            counts['uppercase'] += 1
        elif char.islower():
            counts['lowercase'] += 1
        elif char.isdigit():
            counts['digit'] += 1
        else:
            counts['other'] += 1
    return counts

input_string = input('Enter a string: ')

# 使用字符串方法统计字符数量
counts = count_chars(input_string)
print('Using string methods: ', counts)

# 使用正则表达式模块re统计字符数量
counts_regex = count_chars_regex(input_string)
print('Using regex: ', counts_regex)
