Issues with while loop, while (var != 0): does not work, but while (var !=''): works - danilo - Apr-14-2019
Hi there,
I have an issue (line 44 of this code) when using this statement, it creates an infinite loop:
while capital != 0:
However, everything works fine when using this one:
while capital != '':
The idea for this program is to stop when 0 is the input not when you just press enter.
Here the whole code, any idea why this is happening?
def main():
capitals = create_capitals()
current_state, value = capitals.popitem()
capital = input(('What is the capital of ' + current_state + '? (or enter 0 to quit): '))
look_up(capitals, value, capital)
def create_capitals():
capitals = {'Alabama': 'Montgomery', 'Alaska': 'Juneau',
'Arizona': 'Phoenix', 'Arkansas': 'Little Rock',
'California': 'Sacramento', 'Colorado': 'Denver',
'Connecticut': 'Hartford', 'Delaware': 'Dover',
'Florida': 'Tallahassee', 'Georgia': 'Atlanta',
'Hawaii': 'Honolulu', 'Idaho': 'Boise',
'Illinois': 'Springfield', 'Indiana': 'Indianapolis',
'Iowa': 'Des Moines', 'Kansas': 'Topeka',
'Kentucky': 'Frankfort', 'Louisiana': 'Baton Rouge',
'Maine': 'Augusta', 'Maryland': 'Annapolis',
'Massachusetts': 'Boston', 'Michigan': 'Lansing',
'Minnesota': 'Saint Paul', 'Mississippi': 'Jackson',
'Missouri': 'Jefferson City', 'Montana': 'Helena',
'Nebraska': 'Lincoln', 'Nevada': 'Carson City',
'New Hampshire': 'Concord', 'New Jersey': 'Trenton',
'New Mexico': 'Santa Fe', 'New York': 'Albany',
'North Carolina': 'Raleigh', 'North Dakota': 'Bismarck',
'Ohio': 'Columbus', 'Oklahoma': 'Oklahoma City',
'Oregon': 'Salem', 'Pennsylvania': 'Harrisburg',
'Rhode Island': 'Providence', 'South Carolina': 'Columbia',
'South Dakota': 'Pierre', 'Tennessee': 'Nashville',
'Texas': 'Austin', 'Utah': 'Salt Lake City',
'Vermont': 'Montpelier', 'Virginia': 'Richmond',
'Washington': 'Olympia', 'West Virginia': 'Charleston',
'Wisconsin': 'Madison', 'Wyoming': 'Cheyenne'}
return capitals
def look_up(capitals, value, capital):
correct = 0
wrong = 0
while capital != 0: # Here is the problem
if value == capital:
print('That is correct.')
correct = correct + 1
elif value != capital:
print('That is incorrect.')
wrong = wrong + 1
else:
break
current_state, value = capitals.popitem()
capital = input(('What is the capital of ' + current_state + '? (or enter 0 to quit): '))
print('You had', correct, 'correct responses and',
wrong, 'incorrect responses.')
main()

typo: it's capitals
I see you have both, moved too quickly
looks like capital is text, so can't test for 0
try:
while capital != '0': # Here is the problem
