I want to mix the list that stores the objects.
random.shuffle I don't know why, but None keeps returning, so I can't write it.
I think it's because there's an object in the list, not a normal type like int
Is there any other way to mix the list elements other than random.shuffle?
import random
class a:
foo = "bar"
a1 = a()
a2 = a()
b = [a1,a2]
print random.shuffle(b)#None
random.shuffle can be written even if the element in the list is an object of a user-defined class.
This is the case when the print is wrong.
shuffle is not the result of mixing, but None is returned
print random.shuffle(b) of course prints None.
To output normally
import random
class a:
foo = "bar"
a1 = a()
a2 = a()
b = [a1,a2]
random.shuffle(b)
for i in b:
print i.foo
