在Python中用到的格式有三种:lower_underscore、UPPER_UNDERSCORE、CamelCase,不会用到mixedCase。 lower_underscore:小写字母跟下划线(除了常量和类名,剩下的所有名字都是小写下划线,包括:module模块、variable变量、function函数、method方法,他们在Python中通常被看做是一个变量被使用、被传递,所以他们的命名方式是一致的...
So, you could rewrite the loop header to look like this: for name, phone, _ in contacts:. In this case, the underscore represents the email variable, which you aren’t using in the body of the loop.Naming Variables in PythonThe examples you’ve seen so far use short variable names. ...
We are not allowed to use special characters or spaces in variable naming exceptunderscore (_). E.g., Tools_QA is permitted, but Tools QA or Tools@QA is not allowed We should use analphabet or underscore (_) to start a variable name. One can initialize a variable with a value using ...
1. Python Variable Naming Convention While Python is flexible with variable names, there are a few rules and conventions: Variable names must start with a letter (a-z, A-Z) or an underscore (_). Variable names can contain letters, numbers, and underscores. Variable names are case-sensitive...
Class names should follow the UpperCaseCamelCase convention Python’s built-in classes, however, are typically lowercase words Instance variables, methods, and functions Instance variable names should be all lowercase Use underscore to add new words to instances of variables Non-public instance variable...
The Python community uses the underscore character (_) as part of other naming conventions. Here’s a summary of what PEP 8 says about using this character in names: ConventionExampleMeaning Single leading underscore _variable Indicates that the name is meant for internal use only Single trailing...
There is no concept of private variables in Python programming. So, if you want a variable to be treated as private, there is a convention to start the name with an underscore. This hints to the other developers that this variable is not meant to be used and it can change its behavior...
Variable naming convention: Variable names are composed of letters, numbers, and underscores, cannot start with numbers, and are case-sensitive. For example: ‘my_variable = 10’. Common data types: Integer (int): indicates an integer, such as ‘10’ and ‘-5’. Float: Represents a deci...
A double underscore prefix causes the Python interpreter to rewrite the attribute name in order to avoid naming conflicts in subclasses. This is also calledname mangling- the interpreter changes the name of the variable in a way that makes it harder to create collisions when the class is extende...
Underscore symbol (_) Example total_addition TOTAL_ADDITION totalAddition Totaladdition Rule 2: The variable name and constant name should make sense. Note: we should always create a meaningful variable name so it will be easy to understand. That is, it should be meaningful. ...
