I am trying to convert for loop to while loop in python and I am not very sure how to do it. Need some help here, thanks! This is what I am working with :

with open('name.csv') as labelcsv:
    reader = csv.reader(labelcsv)
    name = []
    namenumber = []
    for row in reader:
        tags.append(row[0])
        namenumber.append(row[1])

Why do you want to do that? – Zero Piraeus 18 hours ago
    
reader has built-in funcions specially for for-loop so may not be easy to create while-loop. – furas 18 hours ago

Is it possible that you explain what this code does for row in reader: tags.append(row[0]) namenumber.append(row[1]) – Wei Ping Moh 17 hours ago

I don't know what's benefit to change it

with open('name.csv') as labelcsv:
    reader = csv.reader(labelcsv)
    name = []
    namenumber = []
    row = next(reader, None)
    while row:
        tags.append(row[0])
        namenumber.append(row[1])
        row = next(reader, None)
