I am working on a data analysis project, and I have a large Pandas dataframe containing a lot of information. I need to filter this data frame based on specific values of a column, similar to the way we use the in
and not in
operators in SQL.
After some research, I found out that Pandas offers an easy way to achieve this using the isin()
and ~isin()
methods. However, I am still having some trouble implementing this in my code.
Here is an example data frame:
import pandas as pd
df = pd.DataFrame({'Name': ['John', 'Jane', 'Bob', 'Alice'],
'Age': [25, 30, 35, 40],
'City': ['New York', 'London', 'Paris', 'Tokyo']})
I want to filter this data frame to get all rows where the city column contains either ‘New York’ or ‘Paris’. In SQL, I would do something like:
SELECT * FROM df WHERE City IN ('New York', 'Paris');
How can I achieve the same result in Pandas using the isin() method? Additionally, are there any other ways to achieve this filtering using Pandas? I would appreciate any help or advice on this topic.
Thank you!
