私は私のコードでエラーを解析抱えているが、以下のコードとほぼ理解できるデータセットはTypeError：のstrptime（）の引数1：のstrptime（引数1 strをしなければならない）、
import numpy as np
import pandas as pd
from datetime import datetime as dt
data0 = pd.read_csv('2009-10.csv')
data1 = pd.read_csv('2010-11.csv')
def parse_date(date):
if date == '':
return None
else:
return dt.strptime(date, '%d/%m/%y').date()
data0.Date = data0.Date.apply(parse_date)
data1.Date = data1.Date.apply(parse_date)
はTypeErrorあるフロート状態にしません
