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", ...
print("Record name is:", R1.name) # Record name is: My Record 9. Python Tuples Methods 9.1. any() 返回True如果至少一个元素存在于元组,并返回False如果元组是空的。 print( any( () ) ) # Empty tuple - False print( any( (1,) ) ) # One element tuple - True print( any( (1, ...
(element1, element2, ... , elementn) 从存储内容上看,元组可以存储整数、实数、字符串、列表、元组等任何类型的数据,并且在同一个元组中,元素的类型可以不同,在这个元组中,有多种类型的数据,包括整形、字符串、列表、元组。例如: ("test.com.cn",1,[2,'a'],("abc",3.0)) 需要额外注意的一点是,当...
mylist = ['one', 20 , 5.5 , [10, 15], 'five']You can write nested lists, which means lists inside lists live the above example.Also, you can access any element of the list by its index which is zero based.third_elem = mylist[2]...
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....

一个特别重要的用例是当您希望从Python函数返回多个对象时。 One especially important use case is when you want to return more than one object from your Python function. 在这种情况下,您通常会将所有这些对象包装在一个元组对象中,然后返回该元组。 In that case, you would typically wrap all of those...
Tuple assignment allows for a curious bit of idiomatic Python. Sometimes, when programming, you have two variables whose values you need to swap. In most programming languages, it’s necessary to store one of the values in a temporary variable while the swap occurs. Consider the following examp...
