coma separator is printed on a new line for some reason

[tester_V]

Gentlemen!
Ladies if any?!

I have never seen it before, I'm formatting a string, separating vars by a coma, and for some reason, the last coma is printed on a new line...

print(f"{str(starttime)},{str(endtime)},{str(cell_nm)},{str(hand_nm)},{str(tt)},{str(prod)},") 

I made sure the VARs all are sctrings but still last come is printed on a new line...
I even tried this:

        coma = ","                   
        print(f" PRODUCT = {prod}{coma}")

But still, the coma printed on a new line...
I'm confused how to go around it...

Any help is appreciated.
Thank you!

Dear God!
The problem was in Var {prod}.
Here how I fixed it:

                            ss = f"{starttime},{endtime},{cell_nm},{hand_nm},{tt},{prod}" 
                            ss = ss.strip()                          
                            print(f"** {ss},")

Anyway, I'm glad I solved it.
Thank you!
Have a good night....

I guess prod has at the end of the str a newline character.
You can strip it. I often use rstrip to remove only on the right side of the str whitespace. A newline character is also seen as a whitespace.

delimiter = ","
product_name = "Test 123"
product_name_newline = "Test 123\n"



print("Test without newline")
print(f"{product_name}{delimiter}")
print()

print("Test with newline at the end of the str")
print(f"{product_name_newline}{delimiter}")
print()

print("Test with newline at the end of the str and the prevention")
print(f"{product_name_newline.rstrip()}{delimiter}")
print()

This is a problem you should figure out yourself. Knowing that the newline must be coming from somewhere the first thing I would try is this:

print(f"{prod},")
print(f"{prod.strip()},"

I would expect the first print to have the last comma on a new line, and the second to have the last comma on the same line. Now you know that the prod str has a trailing newline character.

You should study the print command and f'string formatting. There was no need for the str() here:

print(f"{str(starttime)},{str(endtime)},{str(cell_nm)},{str(hand_nm)},{str(tt)},{str(prod)},") 

f'string formatting converts in brackets to a str it it is not already a str.

print(f"{starttime},{endtime},{cell_nm},{hand_nm},{tt},{prod},") 

The above will give the exact same results.

But there is no need for the f'string formatting either.

print(starttime, endtime, cell_nm, hand_nm, tt, prod, '', sep=',') 

Also gives the exact same results.

Thank you again!
I got it...
