Regular Expression for matching words

[snippsat]

You most make test strings to see what happens,and no loop before have test this first.

import re

string_object = '''\
== History ==
=== Further reading ===
My car is blue
2 + 2 = 4
++= & hello='''

pattern = re.compile(r'={2,}.+')
processed = pattern.sub(repl='', string=string_object)
print(processed.strip())

Output:
My car is blue
2 + 2 = 4
++= & hello=

So your regex should work fine and added .strip() to remove the new line that sub leave.
