Usually if lists are short, it would be easy to find out the indexes for the slicing method list[start:end] .
However, if lists happen to be extremely long, finding the indexes for the desired items becomes difficult. Is there a way to address this problem, like a more convenient method?
I don’t think there is one size fits all solution, it depends. You might use the index method to find the index. But this might be problematic if you have duplicate values.
that [::-1] means go through the entire list, and the -1 means do it backward
x = ['a', 'b', 'c', 'd', 'e', 'f']
# look at entire list, go backward
y = x[::-1]
print(y)
# look at entire list, use every 2nd entry
z = x[::2]
print(z)
