➤ Using if ,elif and else condition to making calculator  :
 
num1=int(input("Enter the first number :  "))
 
opr=input("Enter the operation to be operate..('+ - * /) :  ")
num2=int(input("Enter the number :  "))
if( opr==" + "):
  print(num1+num2)
elif( opr==" * "):
  print(num1*num2)
elif(opr==" - "):
  print(num1 - num2)
elif(opr==" / "):
  print(num1/num2)
else:
  print("Invalid choice")
 
OUTPUT :
Enter the first number : 12
Enter the operation to be operate..('+ - * /) : *
Enter the number : 2
