Match set of string representations of Python complex numbers

Question

I am trying to match a set of complex numbers with re.match(). I am pretty sure the regex should work but still Python doesn't return anything.

pattern = '\.\d+\.\d+\w\.'
value = str(complex(17, 80))
string = '' + value
print(re.match(pattern, string).group())

The output should be something like:

(17+80j) 

But instead it is:

AttributeError: 'NoneType' object has no attribute 'group'

Answer 1

Try this:

pattern = r'.\d+.\d+\w.'
