[Matplotlib-users] need a regular expression hint

[Darren D. <dd...@co...>]

I am putting the finishing touches on the new formatter, but I need to figure 
out how to do a regular expression that will match each of these strings:

r'$10$'
r'$+7.3567{\times}10$'
r'$-5.740977777{\times}10$'
r'${\times}10$'

Here is my attempt:

re.compile('\$([(\{\\times\}?)\-+0-9]+)\^\{(-?[0-9]+)\}\$')

Could an Regular Expression Guru please have mercy on me? My head is killing 
me.

Rather than trying to craft the mother of all regexes, you may want o
make a series of them.  Iterate over the series and if one matches,
use it.
