#to multiple lines 另一种方法是使用三重单引号 '''或者三重双引号 """。 三重引号通常用于多行字符串。但它们也可以用作多行注释。除非它们是文档字符串(docstring),否则它们不会生成任何额外的效果。 """This is also a perfect example of multi-line comments""" Python中的文档字符串(Docstring) Docst...
Comments work more or less the same in every programming language. But if you’re new to programming or new to Python, you need an in-depth understanding of how comments work and how to use them. Today, we’ll look at writing comments in Python, how to add comments, how to create a...
2. Multi-line Comments in Python Python does not provide a built-in syntax for traditional block comments (such asJava comments). However, developers often usemulti-line stringsenclosed in triple quotes (single or double) as a workaround to create multiple-line comments. ...

An alternative method for commenting out multiple lines is to use triple-quoted string literals (''' ''' or """ """). While not officially block comments, these string literals are often used as such, especially for multi-line comments or docstrings. To use triple-quoted strings, simply ...
The import should be written at the beginning of the code file, after the module comments and document strings, and before the module global variables and constants declaration. It should be written in the following order: standard library imports - related third-party imports - specific imports ...
- Imports should usually be on separate lines, e.g.: Yes: import os import sys No: import sys, os it's okay to say this though: from subprocess import Popen, PIPE - Imports are always put at the top of the file, just after any module comments and docstrings, and before module glob...
