pandas merge on two columns code example
Example 1: merge two dataframes based on column
df_outer = pd.merge(df1, df2, on='id', how='outer')
df_outer
Example 2: pd merge on multiple columns
new_df = pd.merge(A_df, B_df, how='left', left_on=['A_c1','c2'], right_on = ['B_c1','c2'])
Example 3: join on column pandas
df1.merge(df2,on='columnName',how='left')
Example 4: combine dataframes with two matching columns
merged_df = DF2.merge(DF1, how = 'inner', on = ['date', 'hours'])
Example 5: pandas merge two columns from different dataframes
df_merge_col = pd.merge(df1, df2, on='id')
Example 6: python inner join based on two columns
df = pd.merge(left=df1, right=df2, on=['var_1', 'var_2'], how='inner']
