Is there a way to make a forloop identify it's about to end?

Question

Given this code:

columns = 12
num = 0
for num in range(0, columns+1):
            print(f"{num:>5d}", end=" ")

How can I let the for loop know that this is the last time it will run, so that I can add a newline after the entire output (instead of a space)?

You can add a statement in your loop like:

if num == columns:
    print("")

to add a line, or add a print("") after the loop. Like:

columns = 12
num=0
for num in range(0, columns+1):
    print(f"{num:>5d}", end=" ")
    if num == columns:
        print("")

or

columns = 12
num=0
for num in range(0, columns+1):
    print(f"{num:>5d}", end=" ") 
print("")
