I need to check a string over which I have no control for the first 2
non-white space characters (which should be '[{').
The string would ideally be: '[{...' but could also be something like
' [ { ....'.
Best to use re and how? Something else?
Use pyparsing it is straight forward:
>>> from pyparsing import Suppress, restOfLine
>>> mystring = Suppress('[') + Suppress('{') + restOfLine
>>> result = mystring.parse(' [ { .... I am learning pyparsing' )
>>> print result.asList()
['.... I am learning pyparsing']
You'll get your string inside the list.
Hope this help see pyparsing doc for in depth study.

Sorry the method to parse a string is parseString not parse, please
replace by this line:
>>> result = mystring.parseString(' [ { .... I am learning pyparsing' )
