How to remove leading and trailing zeros in a string? Python

Question

I have several alphanumeric strings like these

listOfNum = [\'000231512-n\',\'1209123100000-n00000\',\'alphanumeric0000\', \'000alphanumeric\']

Answer 1

What about a basic

your_string.strip("0")

to remove both trailing and leading zeros ? If you're only interested in removing trailing zeros, use .rstrip instead (and .lstrip for only the leading ones).

[More info in the doc.]

You could use some list comprehension to get the sequences you want like so:

trailing_removed = [s.rstrip("0") for s in listOfNum]
leading_removed = [s.lstrip("0") for s in listOfNum]
both_removed = [s.strip("0") for s in listOfNum]
