I met a line in python code:
onevariable for(a,b) in range(1,10)
Can you help me how it should be 'read'? Couldn't 'google' any example of 'for' with brackets. Very strange line

Did you try running it to see what happens? – bnaecker Oct 07 '17 at 20:04

1`for(a,b) in range(1,10)` can't work. But you're probably refering to list comprehensions. – Jean-François Fabre Oct 07 '17 at 20:06

@jeanfrancoisefabre but it can't work in a list comp either? – roganjosh Oct 07 '17 at 20:08

@roganjosh you cannot unpack a&b from a range. – Jean-François Fabre Oct 07 '17 at 20:10

@jeanfrancoisefabre Exactly as I was thinking, so a list comp can't make it work. It's just broken code either way I guess. – roganjosh Oct 07 '17 at 20:12

@Jean-FrançoisFabre You can if you replace the built-in `range`... – Stefan Pochmann Oct 07 '17 at 20:19

1@roganjosh you're not pinging me but you're pinging Jean-Francoise Fabre if this user exists (and is a girl :)) – Jean-François Fabre Oct 07 '17 at 20:21

It's just a target list; tuple assignment is available just about everywhere variables are set, including in a comprehension.
