I have two dataframes, I wanted to merge them into one single dataframe based on the matching row. My dataframe looks like this
DF_1
Set_1 Fax_1 Fax_2 Abc_1 45 76 Abc_2 46 77 Abc_3 47 78 Abc_4 48 79 Abc_5 49 80 Abc_6 50 81 Abc_7 51 82 Abc_8 52 83 Abc_9 53 84 Abc_10 54 85
df_2
Set_1 Fax_3 Fax_4 Abc_1 69 42 Abc_2 70 43 Abc_3 71 44 Abc_6 72 45 Abc_5 73 46 Abc_6 74 47 Abc_7 75 48 Abc_8 76 49 Abc_9 77 50 Abc_10 78 51 Abc_11 55 86 Abc_12 56 87 Abc_13 57 88 Abc_14 58 89 Abc_15 59 90 Abc_16 60 91
The second one is a bigger dataframe and what I need as in my output file, as,
Set_1 Fax_1 Fax_2 Fax_3 Fax_4 Abc_1 45 76 69 42 Abc_2 46 77 70 43 Abc_3 47 78 71 44 Abc_4 48 79 72 45 Abc_5 49 80 73 46 Abc_6 50 81 74 47 Abc_7 51 82 75 48 Abc_8 52 83 76 49 Abc_9 53 84 77 50 Abc_10 54 85 78 51
This is what I tried with merge,
merged =df.merge(df_annon, on='Set_1')
merged.head()
But it is just giving me the header as output. Any help or guidance is much appreciated..!!
Try this
merged = df.merge(df_annon, left_index=True, right_index=True, how='inner')
