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.

So you want to remove all "words" of the form NUMBERSxNUMBERS? — Joel Cornett

+1. Minor nitpick: you should never name variables after python builtins. Change str to something else.

@JoelCornett thanks... been writing C# all week... switched it the wrong way >.<
