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, ...

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....
>>> t = ()#empty tuple>>> t = (1,)#tuple with only one element, ',' is necessary 一种看似可以修改的tuple: >>> t = ('a','b', ['A','B'])>>> t[2][0] ='X'>>>t ('a','b', ['X','B']) 表面上看,tuple的元素确实变了,但其实变的不是tuple的元素,而是list的元素...
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...
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]...
With one-dimension arrays, we can index a given element by its position, keeping in mind that indices start at 0. 使用一维数组,我们可以根据给定元素的位置对其进行索引,记住索引从0开始。 With two-dimensional arrays, the first index specifies the row of the array and the second index 对于二维...
Write a Python program to check whether an element exists within a tuple. Visual Presentation: Sample Solution: Python Code: # Create a tuple containing a sequence of itemstuplex=("w",3,"r","e","s","o","u","r","c","e")# Check if the character "r" is present in the 'tuplex...
