[SOLVED] How to make a variable in a string lowercase?

How to make a variable in a string lowercase?

I have seen this Lab assignment on here already and I chose a different route to get the same result. However I keep getting dinged on the case of the variable. The input is inserted in capital, but when I use the variable in a string I get dinged because its uppercase. Any thoughts on a easy way to change it?

menu = {'Oil change' : 35, 'Tire rotation' : 19, 'Car wash' : 7}

service = input('Enter desired auto service:\n') #Zylab enters using Oil change uppercase O

print('You entered:', service)

if (service in menu):
    print('Cost of {}: ${}'.format(service, menu.get(service))) #inserting into the string as uppercase but as part of the sentence needs to be lower case.
else:
    print('Error: Requested service is not recognized')

I tried on line 8 to use:

print('Cost of {}: ${}'.format(service.lower, menu.get(service))) #No good

print('Cost of {}: ${}'.format.lower(service, menu.get(service))) #Not god either

I am still struggling a with formatting placements or if it is even possible.

Solution

You could change the line 8 to:

print('Cost of {}: ${}'.format(service.lower(), menu.get(service)))
