### Week4- individual HW # In that script or notebook. Write a Python function that behaves as follows: # 1.It takes as input the abbreviation of a state in the U. S., such as "MA"or "TX". # 2.It returns as output a pandas Series of the number of confirmed cases of COVID-19 # in that state over time.

import numpy as np import pandas as pd #import cases file df_case = pd.read_csv('covid_confirmed_usafacts.csv') df_case.head()

#import population file df_pop = pd.read_csv('covid_county_population_usafacts.csv') df_pop.head()

#input a abbreviation of a state in the US x = input("Abbreviation of a State: ") #merge info from two dataframes by column State df = df_case.merge(df_pop, on =['State']) #extract population info by input df2= df.loc[df['State'] == x, 'population'] #show the population info df2.head()
