Python Math functions is one of the most used functions in Python Programming. In python there are different built-in math functions. Beside there is also a math module in python. With these functions, we can do different mathematical operations. Here, we will focus on Python Math and learn how to use some of these functions.
Here, we will learn Math in three parts. In the first part we will learn the basic math functions with different coding examples. In the second part, we will learn different Python Math functions. And in the last part, we will learn python math module.
You can also check Python Operators
Here, firstly we will focus basic math operations used in python. We will learn these operations with different python coding examples. So what are these basic operations? These are:
Now, let’s start to learn these basic operations one by one.
You can also check Python While Loop
Below, we will add two numbers and find the result.
We can do the same operation with the below code also.
You can also watch the video of this lesson.
Now, let’s give an example for subtraction.
Below, we will use both subtraction and addition together.
Below, we will use multiplication and find the result.
Now, let’s use multiplication with subtraction.
In the below python coding example, we will use division.
Below, we will use multiplication and division together.
Now, let ‘s use find the difference of a division operation.
Now, let’s do an example that finds the even numbers in a list.
Lastly, let’s talk about power operator(**). Below we will calculate b power of a with power operator (**).
In our last example with math operators, we will use different operators together like below:
We have learned basic python math operations above. Now, let’s learn complex operations with python math functions. These functions can be used also as python for math.
Firtslty, we will start with min() function and max() function. With the sefunctions, we will learn minimum and maximum numbers between the given numbers.
Now, let’s find a to the power of b with a built in math function. This function is pow() function.
Another built-in math function is abs() function. This function returns with the positive value of a given number.
In python there is a built-in module. This module is math module. We can extend math functions with this math module.
We need to import this module to use these math functions. To import this math module we can use “import” code like below:
There are many math functions in math module. Some of these math functions are given below:
There are also more complex functions in math module like:
Here, we will give example for the simpler ones.
Firstly, we will start with math.sqrt() function. With this function we will find the square root of a number.
Now, let’s find the factorial of a number with math.factorial() method.
Now, let’s learn two functions that rounds the given number. Here, there are two functions. One of them is ceil() method that rounds upwards to the nearest integer. The other is floor() method that rounds downwards to the nearest integer.
The other match function is math.pi() function. This is simply pi number.
In this lesson, we have learned Python math operations and python math functions. There are many math fucntions so we have showed examples for some of them only. If you need more complex mathematical functions, you can check all the functions in python math module.
