What is the abs() function in python?

In Python, 'abs()' is a built-in function that returns the absolute value of a number. The absolute value of a number is its value without regard to its sign.

example -

x = -5

y = abs(x)

print(y)  # Output: 5

In the above example, we first assign the value -5 to the variable x. We then use the abs() function to get the absolute value of x and assign it to the variable y. Finally, we print the value of y, which is 5.

Here's an example of using abs() in Python:

Example 1: Getting the absolute value of a floating-point number

x = -3.14

y = abs(x)

print(y)  # Output: 3.14

In this example, we use the abs() function to get the absolute value of the floating-point number -3.14. The result is 3.14, which is the same value without its negative sign.

Example 2: Getting the absolute value of a complex number

z = -2 + 3j w = abs(z) print(w) # Output: 3.605551275463989

In this example, we use the abs() function to get the absolute value of a complex number -2 + 3j. The result is 3.605551275463989, which is the magnitude of the complex number without its sign.

Example 3: Getting the absolute difference between two numbers

a = 5 b = 8 diff = abs(a - b) print(diff) # Output: 3

In this example, we use the abs() function to get the absolute difference between two numbers a and b. The difference between 5 and 8 is -3, but the absolute value of -3 is 3, which is the final output.
