[問題] 讀取dataframe中某一列某一行
https://mybox.ncku.edu.tw/navigate/s/C7780C75A59347E783561806F62FE387GSY
這是我的數據檔案
簡單範例我測試沒問題
但是我用這個數據來測
import numpy as np
import pandas as pd
i=pd.read_csv("taipei.csv",sep=",")
i.head(3)
print (i[1,2])
執行的結果是錯誤
Traceback (most recent call last):
File "<ipython-input-60-a348a131c1bf>", line 1, in <module>
print (i[1,2])
File "C:\Users\user\Anaconda3\lib\site-packages\pandas\core\frame.py", line
