Sette alle elementene i en liste til 0:

list1 = [1, 2, 3, 4]

for inx in range(len(list1)):
    list1[inx] = 0
    print(list1)
    print()

# [0, 2, 3, 4] 
# 
# [0, 0, 3, 4] 
# 
# [0, 0, 0, 4]
#
# [0, 0, 0, 0]

Printe to elementer pr linje. Hindre at index kjører «out of range»:

list1 = [1, 2, 3, 4, 5]

for inx in range(0, len(list1), 2):
    if inx == len(list1) -1:
        print(list1[inx])
    else:
        print(list1[inx], list1[inx] + 1)

# 1 2
# 3 4
# 5
