将字典值转换为数据框

Question

This could be answered somewhere but I can't seem to work any of the solutions with what I have...

I have a following dictionary data_dict:

data_dict:
{'df_0':
     Name    Role       Location
0    Gina    Assistance    NY
1    Jake    Officer       Brooklyn
2    Boyle   Detective     99
3    Scully  Assistance    NY
4    Diaz    Officer       Brooklyn
 'df_1':     
     Name    Role       Location          
5    Hitchcock Detective     99
6    Amy    Assistance    NY
7    Terry    Officer       Brooklyn
 'df_2':  
     Name    Role       Location
7    Terry    Officer       Brooklyn
8    Holt   Detective     99
9    Judy   Assistance    NY
10   Adrian Officer       Brooklyn
}

In the dictionary above df_0, df_1, df_2 are the keys for data_dict and each of the keys is a dataframe that contains columns Name, Role, Location

The output I am seeking is a master_df that combines values from data_dict keys and outputs the following results:

master_df:
     Name    Role       Location
0    Gina    Assistance    NY
1    Jake    Officer       Brooklyn
2    Boyle   Detective     99
3    Scully  Assistance    NY
4    Diaz    Officer       Brooklyn
5    Hitchcock Detective     99
6    Amy    Assistance    NY
7    Terry    Officer       Brooklyn
8    Holt   Detective     99
9    Judy   Assistance    NY
10   Adrian Officer       Brooklyn

Any help / guidance is appreciated!!

Answer 1

You can try using concat function, something like this:

import pandas as pd
master = pd.concat (data_dict.keys())

Answer 2

You an concat and then drop_duplicates() :

master_df = pd.concat([df_0, df_1, df_2]).drop_duplicates()

EDIT: Reading more closely... you are doing this from a dictionary... so try dejdej's answer. You may have to drop duplicates, but I didn't test.

Answer 3

Thanks all!

For my purpose I found this solution to output what I needed:

output = pd.DataFrame()
for k in data_dict:
    output = output.append(data_dict[k], ignore_index=True)

Thank you everyone for your time and suggestions!
