1. Chef is a software developer, so he has to switch between different languages sometimes. Each programming language has some features, which are represented by integers here. Currently, Chef has to use a language with two given features A and B. He has two options --- switching to a language with two features A1 and B1, or to a language with two features A2 and B2. All four features of these two languages are pairwise distinct. Tell Chef whether he can use the first language, the second language or neither of these languages (if no single language has all the required features) The first and only line of each test case contains six space-separated integers A,B,A1,B1,A2,B2. For each test case, print a single line containing the integer 1 if Chef should switch to the first language, or 2 if Chef should switch to the second language, or 0 if Chef cannot switch to either language.

#Explanation: chef has to use a language with two features A and B 
#case 1: if first language has the required features of A1 & B1 that match with features A and B, then print 1
#case 2: if second language has the required features of A2 and B2 that match with features A and B, then print 2
#case 3: Neither language features match with A and B hence cannot switch to either language, then print 0
    
A,B,A1,B1,A2,B2 = map(int,input("Enter A,B,A1,B1,A2,B2:").split())
if(A1==A and B1==B): # test case with features A1 & B1 matching A & B
    print("1","first language")
elif(A2==A and B2==B): # test case with features A2 & B2 matching A & B
    print("2","second language")
else: # test case with features A2 & B1 or B2 & A1 not matching A & B
    print("0","cannot switch to either language")

Enter A,B,A1,B1,A2,B2:2 4 2 4 3 1
1 first language

1. You have prepared four problems. The difficulty levels of the problems are A1,A2,A3,A4 respectively. A problem set comprises two problems and no two problems in a problem set should have the same difficulty level. A problem can belong to at most one problem set. Find the maximum number of problem sets you can create using the four problems. Each test case contains four space-separated integers A1, A2, A3, A4, denoting the difficulty level of four problems. For each test case, print a single line containing one integer - the maximum number of problem sets you can create using the four problems.

#There will be two special cases :
# All problems with distinct output will be 2
# All problems with same output will be 0

A1,B1,A2,B2 = map(int,input("Enter A1,B1,A2,B2:").split())
l = (A1, B1, A2, B2)
a=set(l)
print(l)
print(a)
if (len(a) == 4):
    print(2)
elif (len(a) == 3):
    print(2)
elif (len(a) == 2):
    print(1)
else:
    print(0)

Enter A1,B1,A2,B2:1 2 1 2
(1, 2, 1, 2)
{1, 2}
1

3.Develop a python code to check given two dates d1 and d1 , check whether d1 is less than d2 or d1 is greater than d2 or d1 is equal to d2. (Hint: overload < , > , == operators)

# importing datetime module
import datetime
  
def compdates():
    # date in yyyy/mm/dd format
    date1=  input('Enter a first date in YYYY/MM/DD format: ') #input(datetime.date)
    date2 = input('Enter a second date in YYYY/MM/DD format: ') #input(datetime.date)

    year1, month1, day1 = map(int, date1.split('/'))
    year2, month2, day2 = map(int, date2.split('/'))
    
    if year1 > year2: # date1 year is greater 
        print("d1 is greater than d2") 
    elif year1 < year2: # date2 year is greater
        print("d1 is less than d2")
    elif year1 == year2: # year is same for both dates 
        if month1 > month2:
            print("d1 is greater than d2")
        elif month1 < month2:
            print("d2 is greater than d1")
        else:
            if day1 > day2:
                print("d1 is greater than d2")
            elif day1 < day2:
                print("d1 is lesser than d2")
            else:
                print("d1 is equal to d2")

4. Develop python code to add, subtract, multiply and divide two distances where each distance contains two things of the format KM followed by Meters. (Example: d1 = 4km 500 m and d2 = 3 km 200 m )

class CalculateDist:
    def GetDistance(self):
        self.km = int(input("Enter KM: "))
        self.m= int(input("Enter M: "))

    def PutDistance(self):
        print(self.km,self.m)

    def __add__(self, T):
        R = CalculateDist()
        R.m = self.m + T.m
        R.km = self.km + T.km
        R.km = R.km + (R.m//1000)
        R.m = R.m % 1000
        return R

    def __sub__(self, T):
        R = CalculateDist()
        R.m = self.m - T.m
        R.km = self.km - T.km
        R.km = R.km + (R.m//1000)
        R.m = R.m % 1000
        return R

    def __mult__(self, T):
        R = CalculateDist()
        R.m = self.m * T.m
        R.km = self.km * T.km
        R.km = R.km + (R.m//1000)
        R.m = R.m % 1000
        return R

    def __div__(self, T):
        R = CalculateDist()
        R.m = self.m/T.m
        R.km = self.km/T.km
        R.km = R.km + (R.m//1000)
        R.m = R.m % 1000
        return R

D1 = CalculateDist()
D2 = CalculateDist()

print("Enter first distance")
D1.GetDistance()

print("Enter second distance")
D2.GetDistance()

D3 = D1+D2
print("Result of addition of both distance is")
D3.PutDistance()

D4 = D1-D2
print("Result of substraction of both distance is")
D4.PutDistance()

D5 = D1*D2
print("Result of multiplication of both distance is")
D5.PutDistance()

D6 = D1/D2
print("Result of division of both distance is")
D6.PutDistance()

Enter first distance
Enter KM: 4
Enter M: 500
Enter second distance
Enter KM: 3
Enter M: 200
Result of addition of both distance is
7 700
Result of substraction of both distance is
1 300

1. Develop a class called Box with attributes length, breadth, depth and define required constructor and other relevant methods. Inherit Box class to WeightBox which contains extra attribute as weight. From this extent further as ColorWeightBox which has Color as extra attribute. Develop code for entire scenario using multi-level inheritance.

class Box:
    def __init__(self, lengt, breadt, dept):
        self.lengt = lengt
        self.breadt = breadt
        self.dept = dept
        
    def display(self):
        print("LENGTH : ", self.lengt)
        print("BREADTH : ", self.breadt)
        print("DEPTH : ", self.dept)
class WeightBox(Box):
    def __init__(self, lengt, breadt, dept, weight):
        Box.__init__(self, lengt, breadt, dept)
        self.weight = weight
    def displayData(self):
        Box.display(self)
        print("WEIGHT : ", self.weight)
class ColorBox(Box):
    def __init__(self, lengt, breadt, dept, color):
        Box.__init__(self, lengt, breadt, dept)
        self.color = color
    def displayData(self):
        Box.display(self)
        print("COLOR : ", self.color)  

print("*****WeightBox*****")
W=WeightBox(20, 15, 5, 20)
W.displayData()
print("*****ColorBox*****")
C=ColorBox(15, 10, 5, "red")
C.displayData()

*****WeightBox*****
LENGTH :  20
BREADTH :  15
DEPTH :  5
WEIGHT :  20
*****ColorBox*****
LENGTH :  15
BREADTH :  10
DEPTH :  5
