chars:可选参数,表示需要删除的字符。如果未提供此参数,则默认删除空格。 (在 Python 的strip()方法中,回车符(\r)和换行符(\n)都属于空格的一种形式,都会被默认删除。) 示例: 代码语言:javascript 复制 # 不提供chars s=" Hello, World! "s=s.strip()print(s)# 输出:Hello,World!# 提供chars:","s...

Note: Note: I haven’t changed anything in the regular expression pattern, and the resulting string is the same, only that this time it is included in a tuple as the first element of that tuple. Then after the comma, we have the number of replacements being made, and that is three. ...
The two groups are the user string and the message. The.groups()method returns them as a tuple of strings. In thesanitize_message()function, you first use unpacking to assign the two strings to variables: Python defsanitize_message(match):user,message=match.groups()returnf"{censor_users(us...
@alexm-neuralmagic the unboxing and boxing (conversion between an 8-bit int to a Python int object) can slow down things indeed. We need to turn to array-native ideally, use array as much as possible. Do you know which part of code in vLLM will suffer from this? Maybe we can find...
