python remove all text between first and second comma in string

I have a string like this

gas,buck,12345,10fifty

how can I end up with this string?

gas,,12345,10fifty

>Solution :

One option might be using list comprehension with split and join, although it might be inefficient:

s = "gas,buck,12345,10fifty"

output = ",".join("" if i == 1 else x for i, x in enumerate(s.split(",")))
print(output) # gas,,12345,10fifty

Alternatively, in this specific case, you can use re:

output = re.sub(',.*?,', ',,', s, count=1)
print(output) # gas,,12345,10fifty
