Getting last element of range in Python

Question

This may be an easy question, but could you tell me how I can print the last element in a range, please ? I did in this way:

for j in range (3):
    print(j[2:])      # I only wish to print 2 here

But it says

TypeError: 'int' object is not subscriptable

Could you tell me how to I can get it with this range function, please ?

If you don't need a for loop; just use j = range(3) instead of for j in range(3). — zondo

Then assign a variable before the loop, say numbers = range(3); change the loop to for j in numbers:, and use print(numbers[-1]) — zondo

Using a for loop makes no sense, since you don't need to iterate over the collection, you just need to get the last element. — Paul Rooney

Range returns a list counting from 0 to 2 (3 minus 1) ([0, 1, 2]), so you can simply access the element directly from the range element. Index -1 refers to the last element.

print(range(3)[-1])

I the range is in your collection you should be able to reference that object directly by the index.

if len(j) > 2:
    print("Value: " + j[2])

This loop will go through the list and check if it is the last item, if true, then print the message underneath.

num_list = [28, 27, 26, 25, 24, 23, 22]
 
 for i in range(len(num_list)):

    print(num_list[i])
    if num_list[-1] == num_list[i]:
        print ('last number: ' + str(num_list[i]))`
