You are given a Juice class, which has name and capacity properties. You need to complete the code to enable and adding of two Juice objects, resulting in a new Juice object with the combined capacity and names of the two juices being added.

For example, if you add an Orange juice with 1.0 capacity and an Apple juice with 2.5 capacity, the resulting juice should have: name: Orange&Apple capacity: 3.5

The names have been combined using an & symbol.

Use the a** method to define a custom behavior for the + operator and return the resulting object.

Program Answer >

class Juice:
 def __init__(self, name, capacity):
 self.name = name
 self.capacity = capacity
 def __add__(self, other):
 return self.name + "&" + other.name + " (" + str(self.capacity + other.capacity) + "L)"
a = Juice('Orange', 1.5)
b = Juice('Apple', 2.0)
result = a + b
print(result)

input
No input
Your Output
Orange&Apple (3.5L)
Expected Output
Orange&Apple (3.5L)

In this tutorial we will see Making Free Medium Blog,

First visit medium.com,

& if you don't have a medium account, Create an account, Once the account is created login into your account, Once you are logged in to your medium account click on the profile picture in the top right and select the Write Story option.

Adding Words​

You need to write a function that takes multiple words as its argument and returns a concatenated version of those words separated by dashes (-). The function should be able to take a varying number of words as the argument.

Sample input​

this is great

Sample Output​

this-is-great Recall, using

def concatenate(*args):
    print('-'.join(args))
    

print(concatenate("I", "love", "Python", "!"))

• First thread to print the square of a number entered by user,
• Second thread to print the cube of a number and show the result. Use start and join operations.

 print(name+" : ",num*num)
def cube(name,num):
 print(name+" : ",num*num*num)
try:
 no=int(input("enter number : "))
 thread.start_new_thread( sqr, ("\nThread - 1: Square:", no ) )
 thread.start_new_thread( cube, ("\nThread - 2: Cube :", no ) )
 #join()
 numTuple = ['1', '2', '3', '4']
 print("#".join(numTuple))
except Exception as e:
 print ("Error: ",e)

enter number : 9
1#2#3#4
Thread - 1: Square: : 81
Thread - 2: Cube : : 729
