index in range python code example
Example 1: python access index in for loop
for index, item in enumerate(items):
print(index, item)
#if you want to start from 1 instead of 0
for count, item in enumerate(items, start=1):
print(count, item)
Example 2: python list index out of range
#this will result in an IndexError
arr = ['item',1,None,'hi']
error = arr[10]
Example 3: python range from n to 0
range(N, -1, -1) is better
