将键/值字符串列表转换为map python

"key1:value1,key2:value2,key3:value3"

def str_to_dict(str_list):
    # 分割字符串以获取键值对列表
    pairs = str_list.split(',')
    
    # 创建一个空字典来存储键值对
    result_dict = {}
    
    # 遍历键值对列表
    for pair in pairs:
        # 分割键和值
        key, value = pair.split(':')
        
        # 将键值对添加到字典中
        result_dict[key] = value
    
    return result_dict

# 示例字符串
str_list = "key1:value1,key2:value2,key3:value3"

# 转换为字典
result = str_to_dict(str_list)

# 打印结果
print(result)

{'key1': 'value1', 'key2': 'value2', 'key3': 'value3'}
