Yes. You can use:

print arrayname,

Note the trailing comma ',' character at the end of the print 
statement. In python 2 this is the normal way to stop print from 
adding a newline. It's a silly syntax that has been fixed in python 
3. If your using python 3 then it looks like

print(arrayname, end='')

which makes a bit more sense to me.

By the way what your calling an array, python calls a list. In python 
the word array is usually used to refer to a number of other things.

As a more general comment: are you the author of both programs? If so 
then you can choose a different format for outputting your data. My 
default choice would be to print out each url on a separate line, 
without the square brackets or commas. You can do that with:

for url in arrayname:
    print url

Note that I want print to add the newlines. This is a common way of 
working with text files and this is the reason that print adds a 
newline.
