用元組列表填充 dataframe 列

Question

我有 dataframe 如下所示：

miles uid  
12    235   
13    234   
14    233   
15    236   

一個列表list1如下所示：

[(39.14973, -77.20692),
 (33.27569, -86.35877),
 (42.55214, -83.18532),
 (41.3278, -95.96396)]

我想要的 output dataframe

miles uid lat-long               lat       long
12    235  (39.14973, -77.20692)  39.14973 -77.20692
13    234  (33.27569, -86.35877)  33.27569 -86.35877

我怎樣才能做到這一點

Answer 1

您可以使用：

df['lat-long'] = my_list
df['lat'] = [e[0] for e in my_list]
df['long'] = [e[1] for e in my_list]

output：

Answer 2

如果DataFrame的長度與列表第一列的長度相同，則僅分配，接下來的 2 列使用列表理解：

df['lat-long'] = list1
df['lat'] = [la for la, lo in list1]
df['lon'] = [lo for la, lo in list1]
