What is the job of the "end" argument in the print function?

for example in this code below the with the end the integers stay on the same line but without the it does not.

num = 5
for i in range(1, num +1):
  for j in range(num, i-1, -1):
  print(j, end="")
print()

The end statement for printing in Python allows the programmer to define a custom ending character for each print call other than the default \n

For instance, if you have a function that is to print all values within a list on the same line, you do:

def value(l):
    for items in l:
        print(l, end=' ')

So if the list argued to this function contains the values [1, 2, 3, 4], it will print them in this manner: 1 2 3 4. If this new ending character parameter was not defined they would be printed:

1
2
3
4

The same principle applies for ANY value you provide for the end option.

In Python 3, the default ist end='\n' for the print function which is a newline after the string is printed.

To suppress this newline, one can set end='' so that the next print starts in the same line.

This is unrelated to the for loop.
