分隔字符串中的大写和小写字符

import re

def split_string(string):
    pattern = r'([a-z]+)([A-Z]+)'  # 匹配小写字母和大写字母的分隔
    result = re.sub(pattern, r'\1 \2', string)  # 使用空格替换分隔符
    return result.split()

string = "HelloWorld"
result = split_string(string)
print(result)  # 输出: ['Hello', 'World']

def split_string(string):
    result = []
    current_word = string[0]
    
    for i in range(1, len(string)):
        if string[i].islower() and string[i-1].isupper():
            result.append(current_word)
            current_word = string[i]
        elif string[i].isupper() and string[i-1].islower():
            result.append(current_word)
            current_word = string[i]
        else:
            current_word += string[i]
    
    result.append(current_word)
    return result

result = split_string(string)
print(result)  # 输出: ['Hello', 'World']
