Do not chdir because it messes the pwd for other tests too. Why is it necessary?

pwd is inside the folder which is to be removed.Need to move out of the

typecasting to bool is not necessary

[Nirnimesh, 2012/05/09 19:48:36]

Construct an inline nested function instead of a using multi-line lambda. It
hampers readability. Repeat for all multi-line lambdas in this file

Done.

It returns an object : <_sre.SRE_Match object at 0x01F71D78>, So I need to
typecast it.

It's not necessary. SRE_Match object implicitly evaluates to True
