First things first: what are these magical math functions and why should you care? Well, let me tell ya, they can do all sorts of cool stuff like calculate the square root of a number or find out how many times a given number appears in a list (hint: it’s called “counting” ).

But before we get into the details, let’s take a quick look at some of Python’s most popular math functions. Here are just a few examples to whet your appetite:

1️ `math.sqrt(x)` Calculates the square root of x (duh).
2️ `math.floor(x)` Returns the largest integer less than or equal to x.
3️ `math.ceil(x)` Returns the smallest integer greater than or equal to x.
4️ `math.pow(x, y)` Raises x to the power of y (i.e., calculates x^y).
5️ `math.log10(x)` Returns the logarithm base 10 of x.
6️ `math.sin(x)`, `math.cos(x)`, and `math.tan(x)` Calculate sine, cosine, and tangent respectively (useful for trigonometry).
7️ `math.factorial(n)` Returns the factorial of n (i.e., calculates n!).
8️ `math.gcd(x, y)` and `math.lcm(x, y)` Calculate the greatest common divisor (GCD) and least common multiple (LCM) respectively.
9️ `math.pi` Returns the value of pi (i.e., approximately 3.14).

Now that we’ve covered some of Python’s most popular math functions, let’s take a closer look at how to use them in practice. Here are a few examples:

# Import the math module (required for using these functions)
import math 

# Calculate the square root of 16
print(math.sqrt(16)) # Output: 4.0

# Find out how many times the number 3 appears in a list
my_list = [1, 2, 3, 4, 5]
count = my_list.count(3) # Use Python's built-in count() function to find the number of occurrences
print("The number 3 appears {} times in this list.".format(count)) # Output: The number 3 appears 2 times in this list.

# The math module contains various mathematical functions and constants, such as sqrt() and pi.
# The sqrt() function calculates the square root of a given number.
# The count() function counts the number of occurrences of a given element in a list.
# The format() function is used to insert values into a string, in this case, the value of count.
