Making lists in python

[wingnut2626]

Isn't there a way to split items in a list into text separated by spaces? Like turn

[4, 6, 9]
INTO
4 6 9

[MG&TL]

I'm confident that there's a much more efficient way, but for now (while I research it):



#any list here
some_list = [1, 2, 3]

#blank storage string
some_list_string = ''

#iterate over every item in the list
for num in some_list:
#append the number and a space
some_list_string += str(num) + ' '

print some_list_string


After some research, it turns out that it's quite easy to just convert the list into a string (as python's print does), then remove extraneous characters. E.g.



#Any list here.
some_list = [1, 2, 3]

#Convert to string, remove '[' and ']', and remove commas.
some_list_string = str(some_list).strip('[]').replace(',', '')

print some_list_string


EDIT 2: Python's join is even better, see the people below.

I think the Python way would be:


' '.join(some_list)

EDIT: Or, if it's a list of integers:


' '.join([str(n) for n in some_list])

[Vaphell]

integers need to be converted to strings with str()

>>> l=[4,6,9]
>>> ' '.join(str(x) for x in l)
'4 6 9'

Thanks guys for the help

' '.join(map(str, list))should work, too.
