python练习将 string， list， tuple， dict类型的数据写入到文件中

以下是将不同类型的数据写入文件的示例代码：

1. 写入字符串到文件

text = "Hello, world!"
with open("file.txt", "w") as f:
    f.write(text)

2. 写入列表到文件

my_list = [1, 2, 3, 4, 5]
with open("file.txt", "w") as f:
    for item in my_list:
        f.write(str(item) + "\n")

3. 写入元组到文件

my_tuple = (1, 2, 3, 4, 5)
with open("file.txt", "w") as f:
    for item in my_tuple:
        f.write(str(item) + "\n")

4. 写入字典到文件

my_dict = {"name": "John", "age": 30, "city": "New York"}
with open("file.txt", "w") as f:
    for key, value in my_dict.items():
        f.write(key + ":" + str(value) + "\n")

注意：在写入数据时，要确保将所有数据转换为字符串类型，因为文件只能保存字符串类型的数据。
