如何將UNIX時間戳列表轉換爲熊貓數據框中的日期時間對象列表？

Question

我有一個熊貓數據框df，其中包含格式爲1,475,761,269,562的UNIX時間戳列。

當我嘗試將其與 df["Timestamp"] = pd.to_datetime(df["Timestamp"], unit = "s")轉換，

我得到 OverflowError: Long too big to convert。

我在做什麼錯？

你需要unit='ms'，也許replace,空字符串：

df = pd.DataFrame({'Timestamp':['1,475,761,269,562', '1,475,761,269,562']}) 
print (df) 
      Timestamp 
0 1,475,761,269,562 
1 1,475,761,269,562 

df["Timestamp"] = pd.to_datetime(df["Timestamp"].str.replace(',',''), unit = "ms") 
print (df) 
       Timestamp 
0 2016-10-06 13:41:09.562 
1 2016-10-06 13:41:09.562
