I have some string and I want add small part to it. How can I achieve this in python?

string =ass34_ssa ass56_ssa ass78_ssa,ass93_ssa

for i in string :
i.replace("",",")

#i want the string to look like:

string =ass34_ssa,DER_ass56_ssa,DER_ass78_ssa,DER_ass93_ssa

string = "ass34_ssa ass56_ssa ass78_ssa,ass93_ssa"

parts = string.split()
# if , is in the string, then split on that
for i in range(len(parts)):
    if "," in parts[i]:
        p1, p2 = parts[i].split(",")
        # remove the old part
        parts.pop(i)
        # insert the new parts
        parts.extend([p1, p2])

new_string = ""
for part in parts:
    if "34" not in part:
        new_string += "DER_" + part
        if part != parts[-1]:
            new_string += ","
    else:
        new_string += part + ","

print(new_string)

First, divide the strings into parts if there is a comma in string then further divide that part and add to parts.

2nd, You can add any logic in the 2nd for loop like this if "34" not in part.

Does this answer your question?
