I'm trying to scan a particular column in a dataframe, eg df['x']
for values which I have in a separate list list = ['y', 'z', 'a', 'b']
. How do I make pandas load a new column with the list value if df['x']
contains any, or more than one of the values from the list?
Thanks!
Use this:
In [720]: import pandas as pd
In [719]: if df['x'].str.contains('|'.join(list)).any():
...: df = pd.concat([df, pd.DataFrame(list)], axis=1))
