can only concatenate list (not "int") to list?

see: http://c4m.cdf.toronto.edu/cohort1/winte...tions.html

Specifically In [4]:

not with a slice, but same thing.

essentially nums[0] is considered an int, not a list
concatenate must be list + list, not list + int

so the following works:

n = [1,2,3,4,5]
n1 = n[3:]+n[4:]
print(n1)
