                             Suppress

Converter for ignoring the results of a parsed expression.

Example:

       source = "a, b, c,d"
       wd = Word(alphas)
       wd_list1 = wd + ZeroOrMore(',' + wd)
       print(wd_list1.parseString(source))

       # often, delimiters that are useful during parsing are just in the
       # way afterward - use Suppress to keep them out of the parsed output
       wd_list2 = wd + ZeroOrMore(Suppress(',') + wd)
       print(wd_list2.parseString(source))

prints:

       ['a', ',', 'b', ',', 'c', ',', 'd']
       ['a', 'b', 'c', 'd']

(See also delimitedList.)
