Genentech Interview Questions

You’re given a dataframe df_cheeses containing a list of the price of various cheeses from California. The dataframe has missing values in the price column.

Write a function cheese_median to impute the median price of the selected California cheeses in place of the missing values. You may assume at least one cheese is not missing its price.

Example:

Input:

import pandas as pd

cheeses = {"Name": [
"Bohemian Goat", 
"Central Coast Bleu", 
"Cowgirl Mozzarella", 
"Cypress Grove Cheddar", 
"Oakdale Colby"], 
"Price" : [15.00, None, 30.00, None, 45.00]}

df_cheeses = pd.DataFrame(cheeses)

Output:
