The abs() function of Python's standard library returns the absolute value of the given number. Absolute value of a number is the value without considering its sign. Hence absolute of 10 is 10, -10 is also 10. If the number is a complex number, abs() returns its magnitude.
>>> abs(11.11) 11.11 >>> abs(-11.11) 11.11 >>> abs(2+3j) 3.605551275463989 >>> abs(3-6j) 6.708203932499369 >>> abs(3-4j) 5.0
