Changing string value that is an element of a list

[jacksfrustration]

i am developing a program for a client. I read from a CSV file. Some of the entries in the csv file (for send dates of the reminder or send status are lists). The specific list i have the problem with is a list of "No" values. I want to be able to change a specific "No" from that list to a "Yes". (NOTES:data is a csv file converted into a list of dictionaries, the variable called sent is only True if there is 0 "No" inside the send status cell) I have tried the following
i tried this first..

here is some of my setup code

todays_date = datetime.now().strftime(self.DATE_FORMAT)
data = self.read_csv_file(self.CSV_FILE)

first i tried this:

if sent:

    for ent in data:
        for date in ent["send date"]:
            if date==todays_date:
                ind=ent["send date"].index(todays_date)
                del ent["send status"][ind]
                ent["send status"].insert(ind,"Yes")
self.save_csv_file(self.CSV_FILE, data)

I also tried:

str(ent["send status"][ind]).replace("No","Yes")

finally i also tried

ent["send status"][ind])="Yes"

nothing worked. please help

Instead of inserting something, why not just replace it? like this:
if ent["send status"] == "No":
# Change "No" to "Yes"
ent["send status"] = "Yes"

ent["send status"] = "Yes"

i tried it. it didnt work.
I also tried converting the element to a string and using replace method
lastly i tried getting the index of the day's date and using that index to remove the specific no and insert a yes in instead. Nothing worked

I don't think I am able to help you with this project. I don't have the whole code, so I can't test it. I recommend you read up on CVS files, and how to manipulate them. (https://www.geeksforgeeks.org/writi.../)(https://docs.python.org/3/library/csv.html)
