How to remove integers from strings

I would like to take a list containing integers in strings and remove those integers. Example:

    list = ["1. car","2. laptop","3. phone","4. monitor"]

Becomes:

    list = ["car","laptop","phone","monitor"]

If your the numbers in your strings are always at the start and followed by a period and a space, you can do it using the split method:

L = ["1. car","2. laptop","3. phone","4. monitor"]

L = [s.split(". ",1)[-1] for s in L]

print(L) # ['car', 'laptop', 'phone', 'monitor']

The .isalpha() method can be used:

from string import digits

new_list = [''.join(x for x in i if x.isalpha()) for i in list]

Try using list comprehension with re.sub():

import re

lst = ["1. car", "2. laptop", "3. phone", "4. monitor"] # avoid using list as a variable name, as list is a built-in function.

output = [re.sub(r'\d+\. ', '', x) for x in lst]
print(output) # ['car', 'laptop', 'phone', 'monitor']

The regex can be (or must be) modified according to your full data.
