str1.split('', n)[:-1]

str.split has an optional second argument which is how many times to split. We remove the last item in the list (the leftover) with the slice.

For example:

a = 'foo,bar,baz,hello,world'
print(a.split(',', 2))
# ['foo', 'bar', 'baz,hello,world']  #only splits string twice
print(a.split(',', 2)[:-1])  #removes last element (leftover)
# ['foo', 'bar']
