Intermediate Python

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

Inside the while loop, complete the if-else statement: If offset is greater than zero, you should decrease offset by 1. Else, you should increase offset by 1.

while offset != 0 :
    print("correcting...")
    if offset > 0 :
      offset -= 1
    else : 
      offset += 1    
    print(offset)

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!".

import pandas as pd
cars = pd.read_csv('cars.csv', index_col = 0)
for lab, row in cars.iterrows() :
    print(lab)
    print(row)

Write a for loop that iterates over the rows of cars and on each iteration perform two print() calls: one to print out the row label and one to print out all of the rows contents.
