Intermediate Python

Run the hidden code cell below to import the data used in this course.

# Import the course packages
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt

# Import the two datasets
gapminder = pd.read_csv("datasets/gapminder.csv")
brics = pd.read_csv("datasets/brics.csv")
4 hidden cells

Explore Datasets

Use the DataFrames imported in the first cell to explore the data and practice your skills!

  • Create a loop that iterates through the brics DataFrame and prints "The population of {country} is {population} million!".
  • Create a histogram of the life expectancies for countries in Africa in the gapminder DataFrame. Make sure your plot has a title, axis labels, and has an appropriate number of bins.
  • Simulate 10 rolls of two six-sided dice. If the two dice add up to 7 or 11, print "A win!". If the two dice add up to 2, 3, or 12, print "A loss!". If the two dice add up to any other number, print "Roll again!".
for lab, row in brics.iterrows():
    print("The population of " + row['country'] + " is " + str(row['population']))
import matplotlib.pyplot as plt
import pandas as pd

life_expectancies = gapminder[gapminder['cont'] == 'Africa']['life_exp']

plt.hist(life_expectancies, bins=20, edgecolor='black')
plt.title('Life Expectancies in African Countries')
plt.xlabel('Life Expectancy')
plt.ylabel('Frequency')
plt.show()
import random

for x in range(10):
    roll = random.randint(1, 6) + random.randint(1, 6)
    if roll == 7 or roll == 11:
        print("A win!")
    elif roll == 2 or roll == 3 or roll == 12:
        print("A loss!")
    else:
        print("Roll again!")
