how to iterate over list even if length of list ends ?

Question

f=['f', 'l', 'a', 'm', 'e', 's' ]
length=8

length is inputed by user it can be anything...
now we have to iterate over list using length
like this :

F L A M E S
1 2 3 4 5 6
7 8

here length ends so remover 'L' from the list

F A M E S
1 2 3 4 5
6 7 8

again now remove the 'M' from the list

F A E S
1 2 3 4
5 6 7 8

remove 'S'

F A E
1 2 3
4 5 6
7 8

remove 'A'

F E
1 2
3 4
5 6
7 8

Remove 'E'

now only one letter left now we want this remaining letter as output... hope you got my idea..

Answer 1

print(f[(8 % len(f))-1])

Ratnapal Shende ,

there is a nice behavior using a slice on a list (or other iterables). it does not matter if the start or end index is available in the sequence, no error will be thrown (it is handled internally with a silent exception)

lst = ['l','a','m']

print(lst[1:5]) # ['a', 'm']
print(lst[2:5]) # ['m']
print(lst[3:5]) # []
