Reading CSV file
We can use one Comma Separated Values( CSV ) file and use one of the column as options for a combobox.Download the sample student CSV file from here
We used append method to add elements to the list.
names=[]
path="D:\\my_data\\student.csv" # sample CSV file, use your path
fob=open(path,)
headings = next(fob) # removing header row
for rec in fob:
student=rec.split(',')
print(student)
names.append(student[1]) # name addeduser inputs and then creating dictionary by reading data from the csv file.
Finally use the dictionary to create csv file.
