python怎么批注分块

如果您想在Python代码中添加注释,可以使用#字符。在#后面的任何文本都会被Python解释器忽略,因此它不会影响您的代码执行。例如:
```
# This is a comment
print("Hello, world!") # This is also a comment
```
如果您想将一段代码作为注释块使用,可以使用三个单引号或三个双引号将其包围。这被称为文档字符串(docstring),通常用于为函数或模块提供文档。例如:
```
"""
This is a docstring. It can span multiple lines and is used to document a function or module.
In this example, we define a simple function that takes two arguments and returns their sum.
"""
def add_numbers(x, y):
"""
This is a docstring for the add_numbers function. It explains what the function does, what arguments it takes, and what it returns.
:param x: The first number to add
:param y: The second number to add
:return: The sum of x and y
"""
return x + y
```
在上面的例子中,三个双引号将整个函数定义包含在文档字符串中,该文档字符串解释了函数的作用、参数和返回值。
