Question

Help me with this coding question that involves "For Loop"

Answer 1

FIXED_COST = 1.24

FREE_MINUTES = 3

COST_PER_MINUTE = 0.76

print( "----------------- Chow Mobile -----------------" )

total = 0

nrCalls = int(input('\\Number of long distance phone calls made: '))

for i in range(nrCalls):

minutes = int(input('\\Number of minutes for call #{}: '.format(i+1)))

cost = FIXED_COST

if minutes > FREE_MINUTES:

cost += (minutes - FREE_MINUTES)*COST_PER_MINUTE

total += cost

print('\\Cost for call #{}: ${:,.2f}'.format(i+1, cost))

print('Total cost of all calls: ${:,.2f}'.format(total))

print( "-------------- THANK YOU --------------" )

Step-by-step explanation:

I have improved the display of currency to always use 2 digits. All constants are defined at the top, so that you don't have "magic numbers" inside your code. This makes the purpose of the numbers also more clear.
