read load from csv file for PSS/E

Question

I am trying to read CSV file that updates loads in PSS/E: csv structure is as follows:

10004,10,10
10006,10,10
10007,10,10
10008,10,10

with open('1.csv', 'r') as file:
    reader = csv.reader(file)
    for row in reader:
       loaddatalst = row.split(',')
       loadbus = int(loaddatalst[0])
       loadid = '1'  
       loadp = float(loaddatalst[1])
       loadq = float(loaddatalst[2])
       psspy.load_data_4(loadbus, loadid, [_i, _i, _i, _i, _i, _i], [loadp, loadq, 0, 0, 0, 0])

but I am getting this error: loaddatalst = row.split(',') AttributeError: 'list' object has no attribute 'split'

Any advice?

updated code after Zach suggestion:

with open('load01.csv', 'r') as file:
    reader = csv.reader(file)
    for row in reader:
       loadbus = int(row[0])
       loadid = '1'  # or loaddatalst [x], x is position of load id in row
       loadp = float(row[1])
       loadq = float(row[2])
       psspy.load_data_4(loadbus, loadid, [_i, _i, _i, _i, _i, _i], [loadp, loadq, 0, 0, 0, 0])
