How do I name a list while generating numbers on the fly?

[DeaD_EyE]

You could create names on the fly.

globals()['my_variable'] = 42

But this is not Pythonic. (ugly code)

Better is to use the right data structure for it.

my_dict = {}
my_dict['my_list1'] = list(range(1, 11))
my_dict['my_list2'] = list(range(11, 21))

print(my_dict)
