关于python中的字符串格式，'；[%s]'；意思是

我看到一行代码：

re.compile('[%s]' % re.escape(string.punctuation))

但是我不知道

[%s]

谁能帮我一下吗

谢谢大家!

这是一种字符串格式语法（它借用了C语言）

例如：

name = input("What is your name? ")
print("Hello %s, nice to meet you!" % name)

这就是程序的样子：

What is your name? Johnny
Hello Johnny, nice to meet you!

你也可以用字符串排版来做这件事

name = input("What is your name? ")
print("Hello + name + ", nice to meet you!")

…但是，格式化通常更容易。 您还可以将其用于多个字符串

输出：

What is your name? Johnny
How old are you? 37
Are you a male or a female? male
Is this correct?
Your name is Johnny, you are 37 years old, and you are male.

现在，请在再问问题之前，看看它们是否存在

这是以前讨论过的问题。试着看一看，看看你是否能找到你要找的东西。可能的复制品意味着这是一个非常好的主意。

What is your name? Johnny
How old are you? 37
Are you a male or a female? male
Is this correct?
Your name is Johnny, you are 37 years old, and you are male.
