An Introduction to Programming, Using Python. By David Schneider

Chapter 6.1, Number 30

State Capitals Assume that the list stateCapitals contains the names of the 50 state capitals. Write a robust code segment that requests the name of a capital and removes it from the list. Using Python

Enter a state capital to delete: Chicago
Not a state capital.
Enter a state capital to delete: Springfield
Capital deleted.

Answer 1

import sys

#list stateCapitals that holds the names of stateCapitals
#I've entered only four names. You can add more names and try.
stateCapitals = ['Springfield', 'Delhi', 'New York', 'New Jersey']
#Reading capital name to be deleted
capital = raw_input("\nEnter a state capital to delete: ")

if capital not in stateCapitals: #if capital is not in the list
    print "\nNot a state capital.\n"
    sys.exit(1) #Exit program with status 1

#Remove capital from list stateCapitals
stateCapitals.remove(capital)
print "\nCapital deleted.\n"
