#Operators
"""
Operands : It is the elements on which the operations are going to be performed
Operators : It is the special symbols that perform operations on variables and values
In Python🐍 Operators are of various types such as :

1- Arithmetic operators
2- Assignment operators
3- Comparision operators
4- Logical operators
5- Bitwise operators
6- Identity operators
7- Membership operators


1️⃣Arithmetic Operators
➡️These operators are used with numeric values to perform common mathematical operations.
+ - *  / // %
"""
print("⭐ARITHMATIC OPERATORS⭐")

a = 20
b = 5
print("First number is ",a)
print("Second number is ",b)
print("Addition ", a + b) #addition operator -> adds two operands
print("Subtraction ", a - b) #subtraction operator -> subtracts second operand from the first operand
print("Multiplication ", a * b) #multiplication operator -> multiply two operands
print("Division ", a / b) #division operator -> divides first operand by second operand
print("Floor Division ", a // b) #⭐floor division operator -> it divides the first by the second and then rounds the result down to the nearest whole number
print("Modulus ", a % b) #⭐modulus operator -> returns the remainder

"""
2️⃣Comparision Operator
➡️These operators compare the values

"""
a = 1
b = 2
print("\nAGAIN\n")
print("⭐COMPARISION OPERATORS⭐")

print("First number is ",a)
print("Second number is ",b)
print("equal to : ", a == b) #equal to
print("not equal to : ", a != b) #not equal to
print("greater than : ", a > b)  #greater than
print("lesser than : ", a < b)  #lesser than
print("greater than equal to : ", a >= b) #greater than equal to
print("lesser than equal to : ", a <= b) #lesser than equal to

"""
3️⃣Logical Operator
➡️Used to combine conditional statements

1- AND : both conditions should be true and satisfied⭐⭐⭐
2- OR  : atleast one condition should be true for the overall true solution , basically it will give TRUE as output.⭐⭐⭐⭐⭐
3- NOT : it will basically inverse the output that has been produced.⭐⭐

"""
print("\n\n⭐LOGICAL OPERATORS⭐\n")

a = 5
b = 6
print("AGAIN\n")
print("First number is ",a)
print("Second number is ",b)
print( a>4 and b>4 ) #5>4 and 6>4 both are true ✅✅ so output will be TRUE ✅.
print( a<b and b<a ) #5<6 is true ✅ but 6<5 is not true 🚫 so the output will be FALSE 🚫.
print( a<b or  b<a ) #5<6 is true ✅ but 6<5 is not true 🚫 so the output will be TRUE ✅.because one condition is satisfied
print(not(a<b and b<a)) #not of FALSE 🚫 is TRUE ✅.

"""
4️⃣Assignment Operators
➡️Used to assign the values

1- Basic Assignment operator =
2- Addition Assignment       +=
3- Subtration Assignment     -=
4- Multiplication Assignment *=
5- Division Assignment       /=
6- Modulus Assignment        %=
7- Exponent Assignment       *=
8- Floor Division Assignment //=

"""
print("\n\n⭐ASSIGNMENT OPERATORS⭐\n")

a = 10 #value 10 is assigned to the variable 'a'
b = 10 #value 10 is assigned to the variable 'b'

# Addition Assignment
print("1- Addition Assignment , lets take an example.")
a = a + 5
print(a) #Output will be 15 , as a is 5
print("But now for b lets do it differently by the addition assignment")
b += 5 #same as b = b + 5
print(b)

#all are the same for 2,3,4,5,6,7 and 8.

"""
5️⃣Identity Operators
➡️Used to compare the memory locations of two objects

1- IS
2- IS NOT
"""
print("\n\n⭐IDENTITY OPERATORS⭐\n")

l1 = [1,2,3]
l2 = [1,2,3]
l3 = l1 #Here the memory location has been successfully assigned 
#Note that the objects within the list doesnt matter
#How the data is in the list whether is it same or not it doesn't matter.
print( l1 is l2) # as we can look l3 is assigned to l1 not l2. If there was in the code that l1 = l2 or l2 = l1 then it would be TRUE.
print( l1 is l3) # It is true because we have assigned.
print( l3 is l1) # Viceversa of that is also possible truly.
print( l1 is not l2 ) #We have not assigned but we know that it is false but with the not it will be TRUE.


"""
7️⃣Membership Operators
➡️Used to test if a sequence is presented in an object.

1- IN
2- NOT IN
"""
print("\n\n⭐MEMBERSHIP OPERATORS⭐\n")
list = [1,2,3,4,5]
print(3 in list) #3 is present in my list. So the output will be TRUE.
print(3 not in list) #Opposite of the above output that will be FALSE.
print(7 in list) #7 is absent in my list. So the output will be FALSE.
print(7 not in list) # as we all know opposite of above output. So the output will be TRUE.
