    Status: Open => Answered

Jan Stránský proposed the following answer:
Hi,

> plot.saveDataTxt('./contact_info'+str(d)+'.txt',vars = ('e_e_e'))

here, the parentheses around ('e_e_e') has no effect and than the code is equal to
vars='e_e_e'
which is interpreted as ('e','_','e','_','e'), the original string split to letters.

Use
vars=['e_e_e'] # list, no comma needed (see below)
or
vars=('e_e_e',) # note the comma, this way it is a tuple with 1 element

cheers
Jan
