finding a pattern in string python

Question

I have a very noisy string input and I am trying to clean it..

So, a part of the noisy string can be something like:

"big $price chair, 5x10"

Now removing symbols and other stuff are done! But I also want to remove

  5x10

for this I did this:

 def remove_numerics(self,string):
    return ' '.join([term for term in string.split() if not term[0].isdigit()])

Which solved this case

but if my string is:

    "big $price chair, x10"

Then it fails? what is a good pythonic way to solve this case also. many thanks.

Answer 1

import re
new_string = re.sub(r', \d*x\d+', '', old_string)

Answer 2

re.sub(r'\b[\dx]+\b', '', "big $price chair, 5x10")
