#burnsteem || PYTHON PROGRAMMING CLASS (THE BASICS) || DAY 6 - PYTHON OPERATORS | WEEK 1 || 25% @null

---

Good day everyone!
Hope you're doing great!! Today is the sixth day of the Python Programming class week 1. If you read my first introductory article for week 1, you will know our sixth topic for the day 6 and all we have to cover for day 6. Please if you have not read the first article please do well to read it here so that you will know what we have for each day of the week.

I brought out this idea of teaching python on steemit because of the need for python programming skills in the world of technology today. This is the new trend in tech now because python can be used for various purposes in many applications ranging from web development, automation, artificial intelligence, software testing to many others. I decided to start this programming class on steemit communities because the communities comprise mainly of people who are still eager to learn new skills. Developers and non-developers alike can use this python.

Note: The English language used in this class is literally understandable by a layman. So let's begin...

PYTHON OPERATORS

---

Operators as the name implies is used to operate on some given input data. In other-words, it is used to perform operations on variables and values. It is used to perform logical or arithmetic operations on operands. We have different types of operators in Python. Let's list the following types of Python operators below.

Types of Operators:

• Arithmetic operators
• Logical operators
• Comparison operators
• Assignment operators
• Membership operators
• Bitwise operators
• Identity operators

We will start with the first one on the list, which is "Arithmetic operators".

---

ARITHMETIC OPERATORS
Arithmetic operators is a type of Python operator used in performing mathematical operations on variables and values. And their operations are mainly operated upon numerical values. Arithmetic operators can be used to perform addition, multiplication, division, subtraction operations e.t.c.

Operator	Name	Description	Syntax
+	Addition	Adds two operands	x+y
-	Subtraction	Subtracts right operand from the left operand	x-y
*	Multiplication	Multiplies two operands	x*y
/	Division	Divides left operand by the right one (always results into float)	x/y
%	Modulus	Divides the left operand by right operand and returns the remainder	x + y
//	Floor division	Divides the first operand by the second operand and rounds the quotient to the nearest lowest integer	x//y

---

For Example,

x = 6
y = 2
print("x + y = ", x + y)
print("x - y = ", x - y)
print("x * y = ", x * y)
print("x / y = ", x / y)
print("x % y = ", x % y)
print("x // y = ", x // y)

Output
x + y = 8

x - y = 4

x * y = 12

x / y = 3.0

x % y = 0

x // y = 3

Python Arithmetic operators

_{Arithmetic operators on Vs code}

From our code in the screenshot above, we have seen the various functions of the arithmetic operators in Python programming.

Note that the division (x / y) operation in our example above results to a floating point value, i.e. 3.0. The floor division (x // y) operation results to a round whole number, i.e. 3. (x % y) returns the remainder of the operation. Others are the normal mathematical operations we know right from our primary school.

NB: Copy the code in the example above and try it out in your text editor. Try this for different separate values for x and y!

---

LOGICAL OPERATORS
Logical operators include Logical AND, Logical OR, and Logical NOT. They're simply used to combine conditional statements.

Operator	Description	Syntax
and	Logical AND: Returns True if both the conditions are true	x and y
or	Logical OR: Returns True if either of the conditions is true	x or y
not	Logical NOT: Returns True if the condition is false, and returns False if the condition is true (reverse the result)	not x

---

For Example,

x = 6 > 2
y = 3 > 1
print(x and y)
print(x or y)
print(not(x and y))

Output
True
True
False

Python logical operators

_{Logical operators}

From the code above, we can see that:

• (x and y) returns True because 6 is greater than 3 and 3 is also greater than 1.
• (x or y) returns True because 6 is greater than 3 or 3 is greater than 1 i.e. either of the condition is true.
• (not(x and y)) returns False because as we have already seen in the AND operation, the result returns True, so negative of True is False, hence the result False.

NB: Copy the code in the example above, and try it out in your text editor. Please make sure to do it for other values respectively, i.e. change the 6, 3, and 1 for other values like 5, 7, 89, 4, and so on...

---

COMPARISON OPERATORS
Comparison operators are simply used to compare two given values, and it returns True or False according to the condition.

Operator	Name	Description	Syntax
>	Greater than	Returns True if the left operand is greater than the right one	x>y
>=	Greater than or equal to	Returns True if the left operand is greater than or equal to the right one	x>=y
<	Less than	Returns True if the left operand is less than the right	x<y
<=	Less than or equal to	Returns True if the left operand is less than or equal to the right	x<=y
==	Equal to	Returns True if both operands are equal	x==y
!=	Not equal to	Returns True if the two operands are not equal	x!=y

For Example

x = 7
y = 20
print("x > y: ", x > y)
print("x >= y: ", x >= y)
print("x < y: ", x < y)
print("x <= y: ", x <= y)
print("x == y: ", x == y)
print("x != y: ", x != y)

Output
False
False
True
True
False
True

Python comparison operators

_{Comparison operators}

From our code above, we can see that:

• (x > y) returns False because 7 is not greater than 20
• (x >= y) returns False because 7 is not greater than or equal to 20
• (x < y) returns True because 7 is less than 20
• (x <= y) returns True because 7 is less than or equal to 20
• (x == y) returns False because 7 is not equal to 20
• (x != y) returns True because 7 and 20 are not equal

NB: Copy the code in the example above and try it out in your text editor. Please make sure to practice along as that is the only way to learn programming fast. Change the values used in this example during your own practice.

ASSIGNMENT OPERATORS
This operator is used for assigning values to a variable.

Operator	Syntax	Same As
=	x = 7	x = 7
+=	x += 7	x = x + 7
-=	x -= 7	x = x - 7
*=	x *= 7	x = x * 7
/=	x /= 7	x = x / 7
%=	x %= 7	x = x % 7
//=	x //= 7	x = x // 7
**=	x **= 7	x = x ** 7
&=	x &= 7	x = x & 7
|=	x |= 7	x = x | 7
^=	x ^= 7	x = x ^ 7
>>=	x >>= 7	x = x >> 7
<<=	x <<= 7	x = x << 7

For Example,

x = 10
print(x)

Output
7

---

x = 10
x = x + 7
print(x)

Output
14

---

x = 10
x = x - 7
print(x)

Output
3

---

x = 10
x = x | 7
print(x)

Output
15

---

x = 10
x = x // 7
print(x)

Output
1

---

x = 10
x = x << 7
print(x)

Output
1280

The (x = x << 7) assignment operator

_{The (x = x << 7) assignment operator}

NB: Please for the sake of time and space, we cannot show the screenshot for all the assignment operators in our text editor here. But please try and check them out one by one in your text editor. Meanwhile, if you want to learn more about Python operators click here or here.

---

MEMBERSHIP OPERATOR
This operator is used to check if the given value is present in the sequence of values, and if it is present or not, it returns True or False. The two member operators are "in" and "not in".

Operator	Description	Syntax
in	Returns True if the value/variable is found in the sequence	x in y
not in	Returns True if the value/variable is not present in the sequence	x not in y

For Example,

x = [1, 2, 3, 5, 6, 7]
print(3 in x)

Output
True

Note: It returns True because 3 is present in the list of integer numbers given in the example above.

---

x = [1, 2, 3, 5, 6, 7]
print(20 not in x)

Output
True

Note: It returns True because 20 is not present in the list of integer numbers given in the example above.

NB: Copy the code in the example above and try it out in your text editor. Please practice more with other list of numbers. Meanwhile, if you want to learn more about Python operators click here or here.

BITWISE OPERATORS
They operate on binary digits. They perform bit-by-bit operations in a program. This operators act on the binary equivalent of the operands as if they were strings of binary digits. For example 1 in binary is 0001, 4 in binary is 0100. I know you may not understand this particular one, but if you want to have more understanding on bitwise operations in computer click here or here.

Operator	Name	Description	Syntax
&	Bitwise AND	Sets each bit to 1 if both bits are 1	x & y
|	Bitwise OR	Sets each bit to 1 if one of the two bits is 1	x | y
~	Bitwise NOT	Inverts all the bits	~x
^	Bitwise XOR	Sets each bit to 1 if only one of two bits is 1	x ^ y
>>	Bitwise right shift	Signed right shift	x>>
<<	Bitwise left shift	Zero fill left shift	x<<

---

For Example,

x = 6
y = 4
print(x & y)
print(x | y)
print(x ~ y)
print(x ^ y)
print(x>>)
print(x<<)

Output
4
6
-7
2
0
48

Python bitwise operators

The screenshot above shows the bitwise operations performed on the operands and their respective outputs.

NB: Copy the code in the example above and try it out in your text editor. I know this particular operator is a bit technical and not friendly but please make use of the following articles to learn more about the bitwise operations in computer.
Article 1 or Article 2.

---

---

IDENTITY OPERATOR
Identity operators are used to check if two values are located in the same memory location, and returns True or False. The identity operators used to achieve this are "is" and "is not". However, they are used to compare objects, not if they are equal, but if they are actually the same object referring to a value stored in the same part of the memory.

Operator	Description	Syntax
is	True if the operands are identical (refer to the same object)	x is True
is not	True if the operands are not identical (do not refer to the same object)	x is not True

---

For Example,

x = 5
y = 5
print(x is y)
a = "Anyiglobal"
b = "Anyiglobal"
print(a is not b)

Output
True
False

Python Identity operator

_{Identity operator}

From the code in the screenshot above, we can see that:

• (x is y) returns True because x and y refers to the same value in the same memory location, i.e. The operands are identical
• (a is not b) returns False because the two operands are identical.

NB: Copy the code in the example above and try it out in your text editor. Meanwhile, you can learn more about Python operators to have broader knowledge of the topic here or here.

NB: THE EASIEST WAY TO LEARN IS TO PRACTICE ALONG.
