Re: var1 = var2 = var3
The interesting thing is how chained assignment is implemented. In C, the
following is an expression, and has a value:
a = b
This leads to the compiler not being helpful for the famous =/== typo in
this like:
if (a = b) { ... }
In python the only expression in:
a = b = c
only has one expression: c
The rest is syntax for the assignment statement, where trailing =
identifies each of the targets to which the value of c is to be assigned.
An assignment statement begins with a series of one or more target
specifiers and ends with a single expression.
(Targets can be more complex, e.g.; x, y = p = 0, 0)

Re: var1 = var2 = var3
what a coincidence, i just asked a similar question 7 hours before you, at python-l...@python.org here's the link, you can extend the discussion there to get more answers, as it is more related to the language rather than django. link: https://mail.python.org/pipermail/python-list/2016-February/703235.html On Wed, Feb 17, 2016 at 1:35 AM, anotherdjangonewby <anotherdjangone...@gmx.de> wrote: > Hi, > > this may be a bit off-topic, but: > > How are expressions like: > > var1 = var2 = var3 > > called Python.

Re: var1 = var2 = var3
That's an assignment statement. See https://docs.python.org/2/reference/simple_stmts.html for more.
