I have the next list:
a = ['1th Word', 'Another Word', '10th Word']
print a.sort()
>>> ['10th Word', '1th Word', 'Another Word']
But I need:
['1th Word', '10th Word','Another Word']
Is there an easy way to do this?
I tried:
r = re.compile(r'(\d+)')
def sort_by_number(s):
m = r.match(s)
return m.group(0)
x.sort(key=sort_by_number)
But some strings do not have numbers and this leads to an errors. Thanks.
