How to remove coma from last item in loop?

Question

I have a loop where I print list items with commas. I want to use a comma with all items except for the last one. how do I do this?

digits = [1,2,3,4,5]
for i in digits:
   print(f'{i},')

Instead of for loop you can use ```join``` function – Akash Pagar Sep 12 '19 at 03:58 — Akash Pagar, Sep 12 '19 at 03:58

You should use str.join:

print(','.join(f'{i}' for i in digits))

I think this is what you are looking for:

digits = [1, 2, 3, 4, 5]
for i in digits:
    if(i == len(digits)):
        print(f'{i}')
    else:
        print(f'{i},')

If the last element is not 5 then this code will not work – SM Abu Taher Asif Sep 12 '19 at 03:59
What are you talking about? Yes it will... I can't even replicate what you mean. – Madison Courto Sep 14 '22 at 20:44
for input: digits = [1, 2, 3, 4, 6] your code will print: 1, 2, 3, 4, 6, – SM Abu Taher Asif Sep 15 '22 at 04:16

Here's a fun example using the index!

digits = [1,2,3,4,5]
output = ""
for i in range(len(digits)):
    output += str(digits[i])
    if digits[i] != digits[-1]:
        output += ", "
print(output)

Fun fact, this will actually work with a list of any length, except 1, and even if the elements of the list are strings, or different ints than the example ones.

you can check for the last elemnt :

digits = [1,2,3,4,5]
for i in digits:
    if i == digits[len(digits)-1]:
        print(f'{i}')
    else:
        print(f'{i},')

for string same code will do:

digits =  ['ali', 'khan', 'malang', 'new', 'baby'] 
for i in digits:
    if i == digits[len(digits)-1]:
        print(f'{i}')
    else:
        print(f'{i},')

output:

ali,
khan,
malang,
new,
baby

it works on digits but not on string... why? – Saadat Ali Sep 12 '19 at 05:07
stars = ['ali', 'khan', 'malang', 'new', 'baby'] for i in stars: if i == len(stars): print(f"<a href='https://hdmoviesplus.gq/search/label/f'>{i}</a> ") else: print(f"<a href='https://hdmoviesplus.gq/search/label/f'>{i}</a>, ") – Saadat Ali Sep 12 '19 at 05:08
this is my code – Saadat Ali Sep 12 '19 at 05:08
the code I have answered also works for string – SM Abu Taher Asif Sep 12 '19 at 05:10
I have added an string example , the code you commented will not work because you checked item with length in if i == len(stars) – SM Abu Taher Asif Sep 12 '19 at 05:12
