Python syntax error using 'with'

Question

I'm trying to compile a project but I'm getting a invalid syntax error during tests with arrow point at the 'h' in with. I haven't written the code and it is fairly years old.

d = Gnuplot.Data(pnts,title=im_title,with='candlesticks')

I tried changing with to something else but then I got different errors. What can I do to fix this issue?

Answer 1

Apparently this code was written before with became one of the reserved keywords .

The (possible) workaround:

 
 
 
  
  d = Gnuplot.Data(pnts, **{'title': im_title, 'with': 'candlesticks'})
 
  

Just checked, it won't work - they were using with as a variable name extensively until Gnuplot.py 1.8 .

The solution for Gnuplot.py 1.8+ is to use with_ argument:

d = Gnuplot.Data(pnts, title=im_title, with_='candlesticks')

Answer 2

In PEP 8 - Style Guide for Python Code, the following guidance appears in the section Descriptive: Naming Styles :

single_trailing_underscore_ : used by convention to avoid conflicts with Python keyword

ie:

d = Gnuplot.Data(pnts,title=im_title,with_='candlesticks')
