What is the best way to to remove leading zeroes and end up with the following.
(128, 20, 8, 255) -- I do not care about spaces
You could use a regexp:
import re
...
re.sub(r"(?<![0-9])0+(?=[0-9])", "", "(128, 020, 008, 255)")
I post this because I think it works (interesting corner cases are 10005
and 000),
Seeing this makes me realize that mine will eliminate any numbers that
are all leading zero, including '0'. Also, forms like '-0042' will be
left unchanged.
Maybe splitting it into integer forms and sending each through
str( int( ) ) would be the safest. This partly does the trick, but
packing the results back into a string that resembles a tuple has
been left as a short exercise for the student:
>>> tuple = '(0128, 020, 000, 008, -0042,255)'
>>> fields = tuple[1:len(tuple)-1].split(",")
>>> for field in fields:
... print( str(int(field)) )
...
128
20
0
8
-42
255
>>>
