How to remove multiple substrings at the end of a list of strings in Python?

I have a list of strings:

lst =['puppies com', 'company abc org', 'company a com', 'python limited']

If at the end of the string there is the word

limited, com or org I would like to remove it. How can I go about doing this?

I have tried;

for item in lst:
   j= item.strip('limited')
   j= item.strip('org')

I’ve also tried the replace function with no avail.

Thanks

You can use this example to remove selected last words from the list of string:

lst =['dont strip this', 'puppies com', 'company abc org', 'company a com', 'python limited']
to_strip = {'limited', 'com', 'org'}

out = []
for item in lst:
    tmp = item.rsplit(maxsplit=1)
    if tmp[-1] in to_strip:
        out.append(tmp[0])
    else:
        out.append(item)

print(out)

Prints:

['dont strip this', 'puppies', 'company abc', 'company a', 'python']
