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.
