从map生成组合字符串

def generate_combination_string(data):
    combination_string = ""
    for key, value in data.items():
        combination_string += key + "=" + str(value) + ","
    combination_string = combination_string.rstrip(",")  # 去除最后一个逗号
    return combination_string

data = {"name": "John", "age": 30, "city": "New York"}
result = generate_combination_string(data)
print(result)

name=John,age=30,city=New York
