In Pandas, how to filter a Series based on the type of the values?

Question

Given a Series like

import pandas as pd

s = pd.Series([\'foo\', \'bar\', 42])

I would like to obtain a \'sub-series\' p

Answer 1

I'd use pd.to_numeric as pointed above.

Alternatively, you can use str.isalpha

In [109]: s[s.str.isalpha().notnull()]
Out[109]:
0    foo
1    bar
dtype: object
