>>> 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...
The index() method returns the index of the specified element in the tuple. In this tutorial, you will learn about the Python Tuple index() method with the help of examples.
Positions are numbered from zero to the length of the tuple minus one. The element at index 0 is the first element in the tuple, the element at index 1 is the second, and so on.Cool! You’ve had a first glance at tuples. It’s time to dive deeper into all of the above ...
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]...
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...
