So when you need to write a comment that spans over multiple lines, I prefer to use a#character before each line, instead of using a multi-line string. Use docstrings, your code editor, or version control The next time you find yourself wanting a multi-line comment in Python, ask yourse...
def ignore_comments(file_path): with open(file_path, 'r') as file: for line in file: line = line.strip() # 去除行首尾的空白字符 if line.startswith('#'): # 判断是否为注释行,以"#"开头表示注释 continue # 跳过当前循环,读取下一行 else: # 处理非注释内容,例如打印到控制台 prin...
#This is a long comment #and it extends #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 comme...

In Python, you have to comment out each individual line to do multiple lines or block comments: #Multiple #lines #of But there is one exception, although it’s a little messy. Python ignores things called “string literals,” which is anything that’s between triple quotes. So, you can ...
We can comment out multiple lines of code by selecting them and then pressingCtrl+/(on Windows/Linux) orCmd+/(on macOS) in many popular code editors and IDEs. This action inserts#symbols at the beginning of each selected line, effectively commenting them out. Repeating the same shortcut un...
# This is a single-line comment. """This is a multiline string that also works as a multiline comment. """ 如果您的注释跨越多行,最好使用单个多行注释,而不是几个连续的单行注释,这样更难阅读,如下所示: """This is a good way to write a comment that spans multiple lines. """ # Thi...
但是,如果你确实遇到了SyntaxError: multiple statements on one line (and no semicolon to separate them)这个错误,那通常意味着你可能有以下几种情况之一: 在一行中写了多个独立的语句,并且没有用分号分隔它们,但你的环境或工具错误地报告了这个错误。这通常不应该发生,因为 Python 通常会忽略没有分号的多个语句...
PEP 8: multiple imports on one line 解决方法:不要在一句 import 中引用多个库,举例:import socket,urllib.error最好写成:import socket import urllib.error PEP 8: blank line at end of line 解决方法:代码末尾行多了空格,删除空格即可 PEP 8: at least two spaces before inline comment ...
4.块注释和行注释 对块注释和行注释也进行了差异化: 块注释解释整块的,没那么一目了然的代码: """ This is a block comment that spans multiple lines """ 行注释用来解释单行,不要过多的使用: # This is a line comment编辑于 2023-12-22 21:22・广东 ...
