Python Exercise: Create a plot of total deaths, confirmed, recovered and active cases Country wise where deaths greater than 150

Python Project: COVID-19 Exercise-10 with Solution

Write a Python program to create a plot (lines) of total deaths, confirmed, recovered and active cases Country wise where deaths greater than 150.

Sample Solution:

Python Code:

import pandas as pd
import matplotlib.pyplot as plt
covid_data= pd.read_csv('https://raw.githubusercontent.com/CSSEGISandData/COVID-19/master/csse_covid_19_data/csse_covid_19_daily_reports/03-19-2020.csv', usecols = ['Last Update', 'Country/Region', 'Confirmed', 'Deaths', 'Recovered'])
covid_data['Active'] = covid_data['Confirmed'] - covid_data['Deaths'] - covid_data['Recovered']
 
r_data = covid_data.groupby(["Country/Region"])["Deaths", "Confirmed", "Recovered", "Active"].sum().reset_index()
r_data = r_data.sort_values(by='Deaths', ascending=False)
r_data = r_data[r_data['Deaths']>50]
plt.figure(figsize=(15, 5))
plt.plot(r_data['Country/Region'], r_data['Deaths'],color='red')
plt.plot(r_data['Country/Region'], r_data['Confirmed'],color='green')
plt.plot(r_data['Country/Region'], r_data['Recovered'], color='blue')
plt.plot(r_data['Country/Region'], r_data['Active'], color='black')
 
plt.title('Total Deaths(>150), Confirmed, Recovered and Active Cases by Country')
plt.show()

Python: Tips of the Day

Find current directory and file's directory:

To get the full path to the directory a Python file is contained in, write this in that file:

import os 
dir_path = os.path.dirname(os.path.realpath(__file__))

(Note that the incantation above won't work if you've already used os.chdir() to change your current working directory, since the value of the __file__ constant is relative to the current working directory and is not changed by an os.chdir() call.)

To get the current working directory use

import os
cwd = os.getcwd()

Documentation references for the modules, constants and functions used above:

  • The os and os.path modules.
  • The __file__ constant
  • os.path.realpath(path) (returns "the canonical path of the specified filename, eliminating any symbolic links encountered in the path")
  • os.path.dirname(path) (returns "the directory name of pathname path")
  • os.getcwd() (returns "a string representing the current working directory")
  • os.chdir(path) ("change the current working directory to path")
