If all your data will be in the same format, as Number Address "000" , "000 abc street, Unit 000"
, you can split the list, remove the comma, and put the list back together, making it a string again. For example using the data you gave:
ori_addr = "Number Address "12345" , "123 abc street, Unit 345""
addr = ori_addr.split()
addr[6] = addr[6].replace(",", "")
together_addr = " ".join(addr)
together_addr is equal to "Number Address "12345" , "123 abc street Unit 345" note that there is no comma between "street" and "Unit."
