Check if a variable is SRE_Match

Question

I need to check if a variable is a regular expression match object.

print(type(m)) returns something like that: <_sre.SRE_Match object at 0x000

Answer 1

As type(m) returns a printable representation I would use:

repr(type(m)) == ""

so you don't have to import the _sre module and don't have to do any additional match call.

That is for Python 2. It seems than in Python 3 the result of type(m) is different, something like <_sre.SRE_Match object at 0x000000000345BE68>. If so I suppose you can use:

repr(type(m)).startswith("<_sre.SRE_Match")

or something similar (I don't have a Python 3 interpreter at hand right now, so this part of the answer can be inaccurate.).
