What are the comma's used for i didnt quite understand there usage? Video : (Variables Python )

Commas used inside the print statement allow you to concatenate smaller strings (text tidbits, essentially) into one long string. In that new string, wherever the comma appears, it is replaced automatically by a space (" "). This concatenation ability allows you to also insert (the values of) variables into that long string.

Consider this code snippet:

full_name = "Jamshaid Ali"
language = "Python"

print(full_name, "is well on the way to being a", language, "guru!")

will print:

Jamshaid Ali is well on the way to being a Python guru!

You can also achieve the same result this way:

full_name = "Jamshaid Ali"
language = "Python"

print(full_name + " is well on the way to being a " + language + " guru!")

Notice that if you concatenate with the + you need to add the spaces to the text. Using the comma, you don't.
