The abs () function takes an argument which is the number that you want to get the absolute value. abs() function takes column as an argument and gets absolute value of that column Hence, the real numbers -2 as well as +2 both will have the same distance of 2. Input array. The absolute value of a complex number z = x + yj is . Now, if we want to get absolute values from a dataset we can use Pandas to create a dataframe from a datafile (e.g., CSV). Let’s discuss certain ways in which this task can be done. In the case of a complex number, the abs () function returns its magnitude. The abs() function takes the number and returns the absolute value. Use the parameter key in the sort_values() function: import pandas as pd ttt = pd.DataFrame({'A': ['a', 'b', 'c', 'd', 'e', 'f'], 'B': [-3, -2, -1, 0, 1, 2]}) ttt.sort_values(by='B', key=abs) will yield: A B 3 d 0 2 c -1 4 e 1 1 b … Submitted by IncludeHelp , on March 02, 2020 In the below program – we are creating a function named get_absolute_value() , it accepts a number and returns the absolute value of the given number.
