dumping generator

[targetsmart]

Right now if I want to dump the contents of a generator object I use ,
a snip from a bigger block of code..

try:
while gen: print gen.next()
except StopIteration:
print "Done"
else:
raise

is there a much simpler way ?

like for printing list we do
list = range(10)
print list
would print
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

Indeed there is:

for item in gen:
print item
print "Done"

Why not something like this:

for i in gen:
print i

like for printing list we do
list = range(10)
print list
would print
[0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

You could coerce the thing into a list:

gen = xrange(10)
print list(gen)

print list( gen )
