Select subset of Data Frame rows based on a list in Pandas

Use isin to return a boolean index for you to index into your df:

In [152]:

df1[df1['A'].isin(x)]
Out[152]:
   A   B  C
1  b  12  1
2  c  14  2

This is what isin is returning:

In [153]:

df1['A'].isin(x)
Out[153]:
0    False
1     True
2     True
3    False
4    False
Name: A, dtype: bool
