Python: Assign variable in if statement?

[ThomasTheDjangoFan]

Hi guys,

coming from php I am wondering if there is a way to do something like this in Python/Django:

if variable = get_a_value_from_function():
  new_stuff = variable

Of course I can use

variable = get_a_value_from_function()
if variable:
  new_stuff = variable


But is there a shortcut similar to php?

Kind regards
Thomas

perhaps something like:

new_stuff = get_a_value_from_function() or get_a_value_from_other_function()

Not as such. Python intentionally didn't include assignment within

statements (mostly conditionals) to avoid the common issue of

assignments-instead-of-equality bugs.

If `new_stuff` has a default value, you could always write.

    new_stuff = some_function() or new_stuff

which will reassign `new_stuff` to itself if `some_function()` returns a

falsy value. If you need a more complex conditional body than just an

assignment, you'll need the long one.

Or, if new_stuff does not already exist, and you want to create a fallback/default value for it, you could use:

    new_stuff = some_function() or "foo"
