使用=将值字符串转换为单个字典

value_string = "key1=value1,key2=value2,key3=value3"

# 按逗号分隔键值对
key_value_pairs = value_string.split(",")

# 创建空字典
result_dict = {}

# 遍历键值对列表
for pair in key_value_pairs:
    # 按等号分隔键和值
    key, value = pair.split("=")
    # 将键值对添加到字典中
    result_dict[key] = value

print(result_dict)

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