I often find myself doing this:
myvariable = 'whatever'
another = 'something else'
print '{myvariable} {another}'.format(
myvariable=myvariable,
another=another
)
Is there a way not to have to name the keyword arguments in this repetitive manner? I'm thinking something along these lines:
format_vars = [myvariable, another]
print '{myvariable} {another}'.format(format_vars)
You can use locals():
print '{myvariable} {another}'.format(**locals())
It's also possible (in Cpython at least) to pick format variables automatically from the scope, for example:
def f(s, *args, **kwargs):
frame = sys._getframe(1)
d = {}
d.update(frame.f_globals)
d.update(frame.f_locals)
d.update(kwargs)
return Formatter().vformat(s, args, d)
Usage:
myvariable = 'whatever'
another = 'something else'
print f('{myvariable} {another}')
See Is a string formatter that pulls variables from its calling scope bad practice? for more details about this technique.
Sure:
>>> format_vars = {"myvariable": "whatever",
... "another": "something else"}
>>> print('{myvariable} {another}'.format(**format_vars))
whatever something else
