How to replace dots in Python?

[sarp ka]

Here's the question I need to replace '.'s with a word such as 'DOT' which will be defined lets say to replace_dots,
So when I use
replace_dots 'hello.'
It should print out
helloDOT

Use string method replace().

>>> s = ".abcdef"
>>> s
'.abcdef'
>>> s.replace(".", "?")
'?abcdef'
>>>

Regular expressions would be a option too
