Answer:
class Car(object):
fuel = 0
def __init__(self, mpg):
self.mpg = mpg
def drive(self, mile):
if self.fuel * self.mpg >= mile:
self.fuel -= mile / self.mpg
else:
print(f"get gas for your {self}")
print(f"Fuel remaining: {self.fuel}")
#classmethod
def get_gas(cls):
cls.fuel += 50
#classmethod
def add_gas(cls, gallon):
if cls.fuel + gallon > 50:
cls.fuel += 10
else:
cls.fuel += gallon
gulf = Car(20)
gulf.get_gas()
gulf.drive(200)
Explanation:
The Car class is defined in Python. Its drive method simulates the driving of a car with fuel that reduces by the miles covered, with efficiency in miles per gallon. The get_gas and add_gas methods fill and top up the car tank respectively.
Answer:
C. leagueName=newPlayers.getLeague(); getLeague() is not a member of Players.
Explanation:
The main method in this code will case an error when trying to run the following line of code...
leagueName=newPlayers.getLeague();
This is because the method getLeague() is being called on a Player object which takes all of its methods from the Player class. Since getLeague() is not a method located in the player class then it cannot be called by an object from that class. Especially since the Player class does not extend to the SoccerPlayers class where the getLeague() method is actually located. Instead, it is the SoccerPlayers class which extends the Players class as its parent class.
Answer:
I think it's C. but not a 100%
Answer:
def validateCreditCard(x):
if type(x)==str and len(x) == 8:
print("Valid credit card number")
else:
print("Invalid credit card number")
validateCreditCard("43589795")
Explanation:
Run the code on your text editor(vs code, sublime, pycharm ) you will get your desired response. If your input is not of type string and not up to 8 digit you will get the response "invalid credit card number" but if it is of type string and up to 8 digit you will get "Valid credit card number".
But remember python works with indentation so when you are transferring this code to your text editor it will run properly well.
I defined the code using the conventional pattern "def"
After defining the function you create a brackets (x) to accommodate your argument x and end it with a semi colon.
Then i use "if" statement to make sure only string argument and 8 digit value will be accepted to print a "valid credit card". if your argument does not pass the if statement condition it will print out the else statement condition which is "Invalid credit card number"
Finally, you have to call your function and test various values.
