想把一个字符串分成三部分

wants to devide a string in three part

string = "M/s Indian Tobacco Co. pvt. ltd., Godfrey Philips, VST Industries",

'''if starting word is M/s then it will devide it three part as end" ," character '''

like so
'''
[."M/s Indian Tobacco Co. pvt. ltd",
 "Godfrey Philips",
 "VST Industries"]'''
def process(string):
    if string.startswith("M/s"):
      return '\n'.join(f'{i}. {p.strip()}' for i, p in enumerate(string.split(','), start=1))
    else:
      # question does not specify what should happen
      return string

print(process("M/s Indian Tobacco Co. pvt. ltd., Godfrey Philips, VST Industries"));

给出输出:

1. M/s Indian Tobacco Co. pvt. ltd.
2. Godfrey Philips
3. VST Industries
