方法一:使用str()函数 最简单的方法是使用Python内置的str()函数将元组转换为字符串。下面是一个示例代码: # 创建一个元组my_tuple=(1,2,3,4,5)# 将元组转换为字符串my_string=str(my_tuple)print(my_string) 1. 2. 3. 4. 5. 6. 7. 运行上述代码会输出:(1, 2, 3, 4, 5),这就是将元组转...
• get() 获取key对应的值,不存在时可指定输出,默认为空 D.get(k[,d]) -> D[k] if k in D, else d. d defaults to None.• has_key() 查看key是否存在 D.has_key(k) -> True if D has a key k, else False• iitems() 转换为以(key, value)组成的列表 D.items() -> list ...

In this example, you create a list of countries represented by string objects. Because lists are ordered sequences, the values retain the insertion order.Note: To learn more about the list data type, check out the Python’s list Data Type: A Deep Dive With Examples tutorial....

The indices for the elements in a are shown below:List IndicesHere is Python code to access some elements of a:>>> a[0] 'foo' >>> a[2] 'baz' >>> a[5] 'corge' Virtually everything about string indexing works similarly for lists. For example, a negative list index counts from ...
write()方法只能往文件中写入字符串,所以在写入前,必须把可迭代对象中的数据转换成字符串(string) 点击查看代码 defcount_words(filename):"""Count the approximate number of all words and unique words in a file."""try:withopen(filename, encoding='utf-8')asfileObj: ...

在本例中,Python向我返回一个新的元组,其中两个元组被放在一起。 And in this case, Python returns a new tuple to me where the two tuples have been put together. 因为元组是序列,所以访问元组中不同对象的方式取决于它们的位置。 Because tuples are sequences, the way you access different objects...
Create a Python Tuple With One Item When we want to create a tuple with a single item, we might do the following: var = ('Hello')print(var)# string Run Code But this would not create a tuple; instead, it would be considered astring. ...
