Erase whole array Python

Note that list and array are different classes. You can do:

del mylist[:]

This will actually modify your existing list. David’s answer creates a new list and assigns it to the same variable. Which you want depends on the situation (e.g. does any other variable have a reference to the same list?).


a = [1,2]
b = a
a = []


a = [1,2]
b = a
del a[:]

Print a and b each time to see the difference.
