Question：
Create an FluidConversion object to convert any number of fluid units to the equivalent number of gallons, quarts, pints, and gills. (There are 128 fluid ounces in a gallon. There are 32 fluid ounces in a quart. There are 16 fluid ounces in a pint. There are 4 fluid ounces in a gill.)
- Get the number of fluid gallons, quarts, pints, gills and ounces as integer from the user; make sure to use a descriptive prompt so the user knows what to enter, for example:
Sample input: Please enter fluid gallons: Please enter fluid quarts: Please enter fluid pints: Please enter fluid gills: Please enter fluid ounces:
- The object contains methods to calculate the total number of gallons, quarts, pints, and gills represented by the original number of fluid ounces and print it out. for example:
- convertGallons() – it just simply convert into gallons, the method will have a return value
- convertQuarts() – it just simply convert into quarts, the method will have a return value
- convertPints() – it just simply convert into pints, the method will have a return value
- convertGills() – it just simply convert into gills, the method will have a return value
- convertOunces() – it just simply convert into the ounces, the method will have a return value
- convert() – convert any number of fluid units to the equivalent number of gallons, quarts, pints, and gills. for example:
- “1 Gallon 6523 fluid ounces is 51 gallon(s)+3 quart(s)+1 pint(s)+2 gill(s)+3 ounce(s)”
- Define __str__(self) show calculated number of gallons, quarts, pints, gills and ounce in one line, for example:
- “6523 fluid ounces is 50 gallon(s)+3 quart(s)+1 pint(s)+2 gill(s)+3 ounce(s)”
Sample program as below:
class FluidConversion:
def __init__(self, gallons=0, quarts=0, pints=0, gills=0, ounces=0):
...
def convertGallons(self):
...
def convertQuarts(self):
...
def convertPints(self):
...
def convertGills(self):
...
def convertOunces(self):
...
def convert(self):
...
def __str__(self):
...
gallons = int(input('Gallons: '))
quarts = int(input('Quarts: '))
pints = int(input('Pints: '))
gills = int(input('Gills: '))
ounces = int(input('Ounces: '))
fc = FluidConversion(gallons, quarts, pints, gills, ounces)
print('it is', fc.convertGallons(), 'gallons')
print('it is', fc.convertQuarts(), 'quarts')
print('it is', fc.convertPints(), 'pints')
print('it is', fc.convertGills(), 'gills')
print('it is', fc.convertOunces(), 'ounces')
print(fc)
fc.convert()
print(fc)
