How to understand the basis and common operations of tuples in Python

This article introduces the knowledge about "how to understand the basics and common operations of tuples in Python". In the actual case operation process, many people will encounter such difficulties. Next, let Xiaobian lead you to learn how to deal with these situations! I hope you can read carefully and learn something!

1. Introduction to tuples

Python tuples are similar to lists, except that the elements of tuples cannot be modified.

Tuples use parentheses, lists use square brackets.

Tuples are easy to create by adding elements in parentheses and separating them with commas.

Format of tuple:

tup=('a ',' b','c',' d') 2. Access Tuples

Tuples can be accessed using subscript indices, which start at 0, to access values in tuples

For example:

tup=('a','b','c','d')print(tup[0])print(tup[1])print(tup[2])print(tup[3])

It can also be accessed by looping

use a for loop

For example:

tup1=('a','b','c','d')for i in tup1: print(i)

Use the while loop

tup1 =('a ',' b','c',' d') i=0# len is the length of computation tup1 while i
