check the ratio of numeric/alphanumric words in given string

[DouOlivia <olivia2046@...>]

Hi there,

Should have performed a search in the list first, but I’m afraid I cannot come out with a good query. Here’s the question: Is there a library that can calculate the ratio of numberic or alphanumeric words in a given string (the actual scenario is to use a document’s content so the string will be very long)? E.g  for string “34 aaa A-7SXD bbb ccc”, the ratio is calculated as 0.4.

 

Thanks.
