❓ FAQ
QWhat is the difference between strip(), lstrip(), and rstrip()?
Astrip() removes from both ends; lstrip() only from the left; rstrip() only from the right. By default all remove whitespace.
QIs the chars parameter a string or a character set?
AIt is a character set. 'xxhelloxx'.strip('x') gives 'hello'. It does not remove a precise "prefix/suffix string".
QDoes strip() remove newlines?
AYes. ' hi\n'.strip() gives 'hi'; whitespace characters such as \n and \t are all removed.
QDoes strip() modify the original string?
ANo, it returns a new whitespace-trimmed string.
