У меня есть фрейм данных pandas с данными и функция, которая добавляет строку в существующий фрейм данных
df = pd.DataFrame()
df.columns = ['A', 'Line', 'B']
# add a new row at the end of non-indexed df
def addRow(self, colData, colNames):
l = len(df)
colList = []
for x in colData :
colList.append(str(x))
new_record = pd.DataFrame([tuple(colDList)])
new_record['Line'] = new_record['Line'].astype(int)
I am getting following error
Traceback (most recent call last):

Может кто-нибудь помочь мне решить ошибку значения
