I need to make regular expression which will match string starts with '->' or '<-' and after that continue with some symbols. For example string '-> arrow 43' should be matched. I don't have much experience in working with re module so it's RegExpression I made '(<\-|\->).+'. But when I run print(re.findall('(<\-|\->).+', '-> arrow 43')) It prints me that ['->']
Why? Shouldn't it prints the whole string? Maybe I have got mistakes in a pattern?

1Try `re.fullmatch()` instead. Python's `re` module interprets parentheses as a *group*, and `findall()` returns only the things inside groups. – Green Cloak Guy Jun 18 '19 at 20:03

Use non-capturing groups instead of capturing, `re.findall('(?:).+', '-> arrow 43')` – Wiktor Stribiżew Jun 18 '19 at 20:04
