I have two dataframes, df1 and df2:
df1 = pandas.DataFrame({'w':['a','b','c'], 'x':['d','e','f']})
df2 = pandas.DataFrame({'w':['b','a','g','c'], 'x':['h','d','i','f'],'y':['j','k','l','m'],'z':['n','o','p','q']})
In [106]: df1
Out[106]:
w x
0 a d
1 b e
2 c f
In[107]: df2
Out[107]:
w x y z
0 b h j n
1 a d k o
2 g i l p
3 c f m q
Both dataframes have same columns df1 and df2. I need to add columns 'y' and 'z' on df2 to df1 such that the values in columns 'w' and 'x' are identical.
The end result would be:
w x y z
0 a d k o
1 c f m q
