Pyparsing: word with at least one non-digit character

Question

How does one define a pattern for a "word with at least one non-digit character" (anywhere in the word) using pyparsing Word() and friends?

The regex solution would be:

Regex("[a-z0-9]+[a-z][a-z0-9]+") 

I tried things along the line of:

Combine(Optional(Word(alphanums)) & Word(alphas))

There must be a solution based on FollowedBy / NotAny / SkipTo but I have not figured that out.

Answer 1

I actually think the Regex you would want would be:

Regex("[0-9]*[a-z][a-z0-9]*")

So putting this together using pyparsing classes would be:

Combine(Optional(Word(nums)) + Word(alphas,alphanums))

But at parse time, the Regex will be much faster.
