Question

I wrote the line below for multiple spaces , how do i include the tab too?

ModCon = re.sub('\s{2,}', ' ', content)

Answer 1

To OR characters, you can just use a character class:

content = re.sub("[ \t]{2,}", " ", content)

You can OR arbitrary expressions with parentheses and vertical bar:

content = re.sub("( |\t){2,}", " ", content)

Answer 2

Try this

ModCon = re.sub('(\ |\t)+', ' ', content)

If there is one or more spaces or tabs, it becomes only one
