abs() is a Python built in function that finds the absolute value of a number. abs() can be combined with map() to get the absolute values of all numbers in a list and abs() can be run on numpy arrays and pandas columns.

Code used in this video:

# Check absolute value with abs()
x = -5
abs(x)

# Calculate the absolute value of every element in a list

x = [4, 5, -3, -6, -2, 6]

[*map(abs, x)]

# Calculate the absolute vaule of an array

import numpy as np

x = np.array(x)

abs(x)

# Get the absolute value of a Pandas column
import pandas as pd

df = pd.DataFrame({"col1":x})

print(df)

abs(df["col1"])

* Note: YouTube does not allow greater than or less than symbols in the text description, so the code above will not be exactly the same as the code shown in the video! I will use Unicode large ＜ and ＞ symbols in place of the standard sized ones.
