program to find the multiples of a number ( the divisor) out of given five numbers.

-
Print ("Enter five numbers below") num1= float (input("First number:")) num2= float (input("Second number:")) num3= float (input("Third number:")) num4= float (input("Fourth number:")) num5= float (input("Fifth number:")) divisor= float (input("Enter divisor number:")) Count=0 print("Multiples of",divisir, "are:") remainder=num1%divisor if remainder ==0:       print(num1,sep=" ")        Count +=1 remainder=num2%divisor if remainder ==0:       print(num2,sep=" ")        Count +=1 remainder=num3%divisor if remainder ==0:       print(num3,sep=" ")        Count +=1 remainder=num4%divisor if remainder ==0:       print(num4,sep=" ")        Count +=1 remainder=num5%divisor if remainder ==0:       print(num5,sep=" ")        Count +=1 Print() Print(Count,"multiples of",divisor,"found") Output Enter five numbers below First ...

num1=float(input("Enter first number:")) num2=float(input("Enter second number:")) op=input("Enter operator[ + - * / % ]:") result=0 If op == '+':         result=num1+num2 else op =='-':        result=num1-num2 else op =='*':        result=num1*num2 else op =='/':        result=num1/num2 else op =='%':        result=num1%num2 else:       print ("Invalid operator!!") print(num1,op,num2,'=',result) Output Enter first number:5 Enter second number:2 Enter operator[ + - * / % ]: * 5.0*2.0=10.0

program to display a menu for calculating area of a circle or perimeter of a circle.

-
radius=float(input("Enter radius of the circle:")) print("1.calculate area") print("2.calculate perimeter") Choice=int(input("Enter your choice (1or2):")) if choice == 1:    area=3.14159*radius*radius    print("area of circle with radius", radius,'is',area)     else:          perm=2*3.14159*radius          print ("perimeter of circle with radius", radius,'is',perm) Output Enter radius of circle : 2.5         1.calculate area          2.calculate perimeter Enter your choice(1or 2):1 area of circle with radius 2.5 is 19.6349375
