Identify the outcome of the following code:
class Competition:
__raise_amount = 1.10
def __init__(self, name, prize):
self.__name = name
self.__prize = prize
def get_name(self):
return self. name
def get_prize(self):
return self.__prize
def raiseprize(self):
self.__prize = self.__prize * self__raise_amount
race = Competition('Race', 100)
print(type(race))
-
What is the result of the following code?
class Competition:

self.__name = name
self.__prize = prize
rowing = Competition('Rowing', 10000)
print(rowing)

return self.number + other.number
num_1 = MethodSub(10)
num_2 = MethodSub(8)
print(num_1 - num_2)
What is the output?

x.start()
x = threading.Thread(target = sleeping_func)
x.start()
pprint(threading.active_count())
print()
pprint(threading.enumerate())
