#16 Python Tutorial for Beginners | Import Math Functions in Python


Mathematical Functions in Python

Welcome back! In this lesson, we will be exploring mathematical functions in Python. These functions allow us to perform various mathematical operations easily. Let's dive in!

Finding Square Roots

To find the square root of a number, we can use the built-in sqrt function from the math module. For example, to find the square root of 25, we can write:

x = math.sqrt(25)print(x)

This will output 5.0, which is the square root of 25.

The float and ceil Functions

The float function converts a number to a floating-point value, while the ceil function rounds a number up to the nearest integer. For example:

value = 2.5rounded = float(value)print(rounded)value = 2.1rounded = math.ceil(value)print(rounded)

The output of the above code will be:

2.03

The power Function

The power function allows us to raise a number to a specified power. For example:

result = math.power(3, 2)print(result)

This will output 9, which is equivalent to 3 * 3.

Constants in the math Module

The math module also provides some useful constants, such as pi and epsilon. To access these constants, you can use math.pi and math.epsilon respectively. For example:

pi_value = math.piprint(pi_value)epsilon_value = math.epsilonprint(epsilon_value)

The output will be:

3.1415926535897932.718281828459045

Importing Specific Functions from the math Module

If you only need to use specific functions from the math module, you can import them individually. For example, to import the sqrt and power functions, you can write:

from math import sqrt, powerresult = sqrt(25)print(result)result = power(4, 5)print(result)

Conclusion

Mathematical functions in Python make it easy to perform various mathematical operations. Feel free to explore the math module documentation for more functions and details. Happy coding!

#22 Python Tutorial for Beginners | Break Continue Pass in Python

  #22 Python Tutorial for Beginners | Break Continue Pass in Python Introduction Welcome back! In the previous videos, we discussed loops in Python, specifically the for loop and the while loop. In this video, we'll talk about three important keywords: break, continue, and pass. These keywords are useful when it comes to controlling the flow of our code. To demonstrate their usage, let's design a simple vending machine simulation. Vending Machine Simulation First, we'll start by taking input from the user to determine the number of candies they want. Then, we'll use a while loop to print the word "candy" as many times as the user requested. Let's write the code: x = int(input("How many candies do you want? "))i = 1while i <= x: print("Candy") i += 1 When you run this code, it will ask you for the number of candies you want. For example, if you enter 4, it will print "Candy" four times. This is how the vending machine ...

#14 Python Tutorial for Beginners | IDLE Previous Command | Clear Screen? How to Access Previous Commands in IDLE? When working with Python, we often write a lot of code. But what happens when we want to access the same command again? In IDLE, there is no default option to access previous commands. However, you can configure it by following these steps: Go to Options Select "Configure IDLE" Click on "Keys" Scroll down and find "History Previous" Select the up arrow as the shortcut key Click "OK" Now, to access the last command, simply press the up arrow. It's important to note that clearing the screen is not possible in IDLE. The only way to do it is by closing and reopening the program. If you know of a hidden script or technique, please share it in the comments below. Thanks for Reading! https://www.highwaycpmrevenue.com/ka9ix7e0t?key=4807923f98c12e085b5d0cf16291fdec
