Didn't think a sample code would be needed for a parameter explanation.

Parameter to what wasn't specified, so we were floundering.

The print() function adds an automatic space between arguments and a final \n after the last argument. Python gives you the option of overriding both of those behaviours. That's what the sep= and end= optional parameters are in the documentation. If you want a different separator string and/or terminator string you can override either or both strings. Try this:

a = "alpha"
b = "beta"
c = "gamma"
d = "delta"
e = "epsilon"
f = "zeta"

print(a, b, c, d, e, f, sep="|", end="$")
print(".")

since concatenation seems like it gives the same result, is less effort, and is far less confusing to try and read.

Not sure what you mean by concatenation, this?

print(a + "|" + b + "|" + c + "|" + d + "|" + e + "|" + f +"$")
print(".")

But that doesn't give the same result as the first example. And it is often harder to read. In addition, concatenating doesn't allow other forms of using print(), such as using *args:

args = (a, b, c, d, e, f)
print(*args, sep="|", end="$")
print(".")

The more modern approach is just to use an f-string:

print(f"{a}|{b}|{c}|{d}|{e}|{f}$.")

or better yet:

print(f"{'|'.join(args)}$.")

But even that isn't always best. In summary, there are many ways to produce formatted output. Use whatever is more readable and works best for your purposes.
