1.1. Tuple with one element 如果元组仅包含一个元素,则不将其视为元组。它应该以逗号结尾以指定解释器为元组。 元组的例子 tupleWithOneElement = ("hello", ) # Notice trailing comma 1.2. Nested Tuple 一个包含另一个元组作为元素的元组,称为嵌套元组。 嵌套元组 nestedTuple = ("hello", ("python", ...

两种特殊的定义: >>> t = () # empty tuple>>> t = (1,) # tuple with only one element, ',' is necessary 1. 一种看似可以修改的tuple: >>> t = ('a', 'b', ['A', 'B'])>>> t[2][0] = 'X'>>> t('a', 'b', ['X', 'B']) 1. 表面上看,tuple的元素确实变了,但...
The return value fromsplitis a list with two elements; the first element is assigned to uname, the second to domain. >>>printuname monty>>>printdomain python.org 12.3 Tuples as return values Strictly speaking, a function can only return one value, but if the value is a tuple, the effe...
Python Tuple Methods Write a function to modify a tuple by adding an element at the end of it. For inputs with tuple( 1, 2, 3)and element4, the return value should be(1, 2, 3, 4). Hint:You need to first convert the tuple to another data type, such as a list....
在Python中,元组(tuple)可以通过索引和切片来访问其中的元素。索引从 0 开始,一直到元组的长度减 1。下面我们定义一个元组,内容包含多种数据类型,为了帮助大家理解,示例代码如下: # 定义元组my_tuple=(1,"apple",True,3.14,[5,6,7],{"name":"TiYong","age":25})# 使用索引访问单个元素first_element=my...
new_tuple = tuple(element for element in my_tuple if element != 1) # 创建新的元组,跳过需要删除的素 print(new_tuple) # 输出: (2, 3) 将元组转换为列表进行删除后再转换回元组: my_tuple = (1, 2, 3) my_list = list(my_tuple) # 将元组转换为列表 ...
Also, you can access any element of the list by its index which is zero based.third_elem = mylist[2]There are some similarities with strings. You can review the Python programming basics post.Mutable Lists/改变列表Lists are mutable because items can be changed or reordered....
Index -1 corresponds to the last element in the list, while the first element is -len(words), as shown below:Python >>> words[-1] 'corge' >>> words[-2] 'quux' >>> words[-len(words)] 'foo' Slicing also works with lists and tuples. For example, the expression words[m:n]...
