the reference answer GPT ᴼ ᴾ ᴱ ᴺ ᴬ ᴵ < br / > in the HTML text, Spaces and line breaks are blank characters can appear in any position, and will be ignored by the parser. Therefore, if we crawled the HTML text string directly, we might contain a lot of unnecessary Spaces and newlines, which would affect the display of the string.
To solve this problem, you can use string handling functions to remove unnecessary whitespace characters. Here are some common functions:
strip() : Used to remove whitespace characters such as Spaces and newlines at both ends of a string.
replace() : Used to replace one character in a string with another. Multiple consecutive Spaces can be replaced with a single space.
split() : Used to split a string into a list that can be separated by Spaces or other characters.
join() : Used to join the elements of a list into a string. You can concatenate the elements in the list using Spaces or other characters.
Using these functions, you can remove unnecessary Spaces and newlines from HTML text strings, making the strings prettier and easier to handle.
