How to append list of values into a desired string format?

I have two lists like below. I want to convert the list of values into a desired string format like '123,1345;2345,890;'. I tried to use loop and tried to append as list but how do I convert that into a string format.

l1 = [123,4567,80,3456,879]
l2=[98,789,5674,678,9087]

out=[]
for i,j in zip(l1,l2):
    out.append(str(j)+','+str(i)+';')
print(out)
['98,123;', '789,4567;', '5674,80;', '678,3456;', '9087,879;']

Excepted output:-

'98,123;789,4567;5674,80;678,3456;9087,879;'

l1 = [123,4567,80,3456,879]
l2=[98,789,5674,678,9087]

out=[]
for i,j in zip(l1,l2):
    out.append(str(j)+','+str(i))
print(';'.join(out) + ";")

You can join your list with ; to get the desired output

You could use a list comprehension that you then unpack into a single print() call.

l1 = [123,4567,80,3456,879]
l2 = [98,789,5674,678,9087]

print(*[f'{b},{a};' for a, b in zip(l1, l2)], sep='')

Output:

98,123;789,4567;5674,80;678,3456;9087,879;

Or, with a generator:

print(''.join(f'{b},{a};' for a, b in zip(l1, l2)))
