[Pyparsing] Check for tabs

[Hanchel C. <han...@br...>]

Hello!

I'm new to pyparsing and relatively new to Python as well. I'm really astounded by the multitude of functionality that pyparsing has.
My question is pretty basic:
I have a string 'name\tdate\t\tlocation'.
What would I do to ensure that between the 'name' and 'date' there is exactly one tab and between 'date' and 'location' there is exactly two tabs?

Thanks,
Hanchel
