[Tutor] How to remove the comma only at the end?

[Panchanathan Suresh]

Hi everyone,

How to remove the last comma , from the variable members?
I tried members[:-1], members.rstrip(","), but no luck. It is
always returning:
Mike, Karen, Jake, Tasha,

I want it to return Mike, Karen, Jake, Tasha (no comma after Tasha)

Below is my code:

*****
def group_list(group, users):
  members = ""
  members1 = ""
  for x in range(0,len(users)):
      #print(users[x])
      members = members + users[x] + ", "
  return members[:-1]


print(group_list("Marketing", ["Mike", "Karen", "Jake", "Tasha"])) # Should
be "Marketing: Mike, Karen, Jake, Tasha"

*****

Thanks so much,
Suresh
