How do I find one number in a string in Python?

Question

I have a file called something like FILE-1.txt or FILE-340.txt. I want to be able to get the number from the file name. I\'ve found that I can use

numbers = re.f         


        

Answer 1

Another way just for fun:

In [1]: fn = 'file-340.txt'

In [2]: ''.join(x for x in fn if x.isdigit())
Out[2]: '340'
