Python 3 – Learn it quick – Numbers
Working with Numbers
In this lesson we are working with numbers and different arithmetic operations. Python support different types of arithmetic operations like,
-
1. Addition
2. Subtraction
3. Division
4. Multiplication
5. Exponentiation
6. Modulo
7. Floor Division
Addition
You can add numbers by simply mentioning two or more numbers, connected by addition operator “+”
Example :
3 + 3 6
Subtraction
You can subtract one number from another number by connecting the subtraction operator “-“
Example :
6 - 3 3
Multiplication
To multiply one number with another, both needs to be connected by multiplication operator “*”
Example :
6 * 3 18
Division
To perform the division of two numbers, the division operator “/” can be used.
Example :
6 / 3 2
Exponentiation
Exponentiation stands for the multiplying the number n number of times and exponentiation operator is represented by **
Example :
6 ** 2 36
Modulo
The modulo operator is represented using the symbol “%”. The modulo operator returns the remainder of dividing the left hand operand by right hand operand.
Example :
37 % 3 1
Floor Division
The floor division operator is represented using the symbol “//”. Floor division returns the quotient, answer or the result of division, in which the digits after the decimal point will be removed. But if one of the operands(dividend and divisor) is negative, then the result is floored, means rounded away from zero, which means towards the negative of infinity.
Example :
37 // 3 12
| Operator Name | Symbol | Sample Operation | Output |
|---|---|---|---|
| Addition | + | 5 + 5 | 10 |
| Subtraction | – | 10 – 6 | 4 |
| Multiplication | * | 8 * 6 | 48 |
| Division | / | 37 / 3 | 12.3333 |
| Exponentiation | ** | 6 ** 2 | 36 |
| Modulo | % | 37 % 3 | 1 |
| Floor Division | // | 37 // 3 | 12 |
In the below excercise, we performing the operations using the operators mentioned in this lesson.
#Print the sum of values 5 and 6
sum = 5 + 6
print(sum)
#Subtract 4 from 10 and print the value
diffr = 10 - 4
print(diffr)
#Multiple 3 with 9 and print the value
mult = 3 * 9
print(mult)
#Divide 56 with 2 and print the value
div = 56 / 2
print(div)
#Combination of arithmetic operation and print the value
total = 21 + 45 * 78 / 67.6
print(total)
# Test the Exponentiation operator. Perform exponentiation 8 to the power of 6
exp = 8 ** 6
print(exp)
# Modulo operator. Obtain the remainder of division
modl = 37 % 3
print(modl)
# Floor Division operator. Obtain the remainder of floor division
flr = 37 // 3
print(flr)
# Print the sum of values 5 and 6
11
# Subtract 4 from 10 and print the value
6
# Multiply 3 with 9 and print the value
27
# Divide 56 with 2 and print the value
28.0
#Combination of arithmetic operation and print the value
72.92307692307693
# Test the Exponentiation operator. Perform exponentiation 8 to the power of 6
262144
# Modulo operator. Obtain the remainder of division
1
# Floor division operator. Obtain the remainder of floor division
