a=1,b=3,c=4 函数Functions 由两部分组成:header和body header用于定义函数接口(函数名称与参数) 当函数被调用时,参数将会作为变量被提供给函数的body部分 可以提供多个参数(用,分隔),也可以不提供参数 header 以:结尾,代表后面会跟着body部分 body包含函数所需要执行的操作 语句需要

In this tutorial, you'll learn how to use global variables in Python functions using the global keyword or the built-in globals() function. You'll also learn a few strategies to avoid relying on global variables because they can lead to code that's diffi
Variables in a program include two types: global variables and local variables. Global variables are variables that are defined outside of functions and are valid throughout program execution. A local variable is a variable that is used inside a function, is only valid inside the function, and ...
Variables are an essential concept in Python programming. They work as the building blocks for your programs. So far, you’ve learned the basics of creating variables. In this section, you’ll explore different ways to use variables in Python....

Learn to create and modify the global variable in Python with examples. Use global variables across multiple functions and modules. Understand the use of the globals() function
The declaration and assignment of constant in Python done with the module. Module means Python file (.py) which contains variables, functions, and packages. So let’s create two modules, constant.py and main.py, respectively. In the constant.py file, we will declare two constant variables, ...
In Python variables,literals,and constants have a "type". Python knows the difference between an interger number and a string For example "+" means "addition" if something is a number and "concatenate" if something is a string >>>ddd=1+4 ...
