我有兩個數據幀 我的第一數據幀,start_df_1
,看起來像這樣:的Python:添加一列到大熊貓數據幀
start_df_1
0
0 3Degrees_Inc
1 3Degrees_Inc
2 3Degrees_Inc
3 3Degrees_Inc
4 3Degrees_Inc
5 3Degrees_Inc
6 3Degrees_Inc
7 3Degrees_Inc
8 3Degrees_Inc
9 3Degrees_Inc
10 3Degrees_Inc
我的第二數據幀friends_df
看起來像這樣:
friends_df
0
0 MEGreenPower
1 LympheDIVAs
2 Ecopreneurist
3 issielapowsky
4 NatureClimate
5 miketuritzin
6 greenbang
7 GoodCleanTech
8 EDFbiz
9 adavies47
10 petedanko
我試圖建立一個新的數據幀,這樣的:
concatenated_df
User Follower
0 MEGreenPower 3Degrees_Inc
1 LympheDIVAs 3Degrees_Inc
2 Ecopreneurist 3Degrees_Inc
3 issielapowsky 3Degrees_Inc
4 NatureClimate 3Degrees_Inc
5 miketuritzin 3Degrees_Inc
6 greenbang 3Degrees_Inc
7 GoodCleanTech 3Degrees_Inc
8 EDFbiz 3Degrees_Inc
9 adavies47 3Degrees_Inc
10 petedanko1 3Degrees_Inc
注意新列被添加,並且第一列和第二列分別被命名爲「用戶」和「追隨者」。 我想:
EDGE_LIST1 = pandas.DataFrame.from_dict({'User':friends_df,
'Follower': start_df_1}, orient='columns')
但是它扔我一個錯誤:
ValueError: If using all scalar values, you must must pass an index
請你幫助我嗎?謝謝。
