The last two should be the same. For what values of x and y are you getting different answers? The first one really is different. If x=3 and y=5, the first one is abs(3)-abs(5) = 3 - 5 = -2 where as the second one is abs(3-5) = abs(-2) = +2 More on reddit.com

July 26, 2022Where to find the abs() source code?
Here: https://github.com/python/cpython/blob/v3.8.0/Python/bltinmodule.c#L302
Which uses PyNumber_Absolute, which is here: https://github.com/python/cpython/blob/v3.8.0/Objects/abstract.c#L1236
Which usesnb_absolute which is implemented by whatever object is being used, e.g. for a float it is implemented here (there's mapping further up the code that redirects nb_absolute to float_abs): https://github.com/python/cpython/blob/v3.8.0/Objects/floatobject.c#L822
Which uses the c functions fabs: https://pubs.opengroup.org/onlinepubs/009695399/functions/fabs.html

October 4, 2018Absolute value of an index in python
That's because what's on the right isn't a number. It's a slice of a list or string. If lines[firsttag] is a string then you should just be able to int() or float() around it first (depending on if it's an integer or floating point value) to get it into a number and then you can call abs on it. Example: >>> data = "12-34546" >>> data[2:4] '-3' >>> int(data[2:4]) -3 >>> abs(int(data[2:4])) 3 >>> More on reddit.com

Python Absolute Value – abs() for real and complex numbers – LearnDataSci
Applying the abs() function to a real number returns the magnitude of that number. We can define a real number as being on the real number line, represented in the image below. The magnitude of a real number refers to its distance along the line from the origin. The sign of the number alludes to which direction along the line the number is; positive values are along the positive axis, and negative ones are along the negative axis. In the quick example shown in the introduction, -5 is a real number.

Because for complex numbers abs(number) will return magnitude of Complex Numbers.
Magnitude value will counted as : √x2+y2 = √(3² + 4²) = √(9 + 16) = √(25) = 5.0
So abs with complex number will return magnitude of complex numbers.

As the rest of the answers stated above, 3+4j is a complex number and the formula of calculating the absolute value of a complex number x+yi is sqrt( (x^2) + (y^2) ). In your case it's:
sqrt(3^2 + 4^2) = sqrt(9 + 16) = sqrt(25) = 5
