equivalent functions?

[wietse]

Hello,

I'm reading "Text processing in Python" by David Mertz. In there he
defines a function

apply_each = lambda fns, args=[]: map(apply, fns, [args]*len(fns))

I thought that this would be equivalent to:

apply_each = lambda fns, args=[]: [f(args) for f in fns]

Can anybody confirm this? If not, how are they different?
Thanks,
Wietse

Very close... it is equivalent to:

apply_each = lambda fns, args=[]: [f(*args) for f in fns]

The asterisk in f(*args) expands the sequence to fill the arguments to
f, where as f(args) would pass the args as only the first argument to
the function.

apply is deprecated, replaced by the syntax: function( *args,
**keywords )
