Delete Extra Space from Values In List

Question

I have a list of numbers in Python all with a extra space in the front. How do I remove the extra space (so that only the numbers are left)? A short example is below (note

Answer 1

For your case, with a list, you can use str.strip()

l = [x.strip() for x in List]

This will strip both trailing and leading spaces. If you only need to remove leading spaces, go with Alex' solution.

Answer 2

map(str.strip, List)

or

map(lambda l: l.strip(), List)

Answer 3

Use str.lstrip here, as the white-space is only at the front:

List = [s.lstrip() for s in List]
# ['5432', '23421', '43242', ...]

---

Or in this case, seeing as you know how many spaces there are you can just do:

List = [s[1:] for s in List]
