[Python 2.4.3 (#69, Mar 29 2006, 17:35:34) [MSC v.1310 32 bit (Intel)] on win32]
Given the following: >>> sum(i for i in range(10)) 45 >>> def f(*args) : print args ... >>> f(i for i in range(10)) (<generator object at 0x00A79788>,) >>> def f(a,*args) : print a,ar ... >>> f(4,i for i in range(10)) File "<stdin>", line 1 SyntaxError: invalid syntax Why does Python allow generator expression parenthesis to be mixed with function call parenthesis when there is only one parameter ? IMHO this should be forbidden, usage must not be different when there is only one parameter and when there are more parameters. User should all times explicitly use () for a generator expression and [] for a list comprehension expression. -- http://mail.python.org/mailman/listinfo/python-list
