I think something as basic as an angle/arg of complex number
definetly belongs to the interface, and it would not even require a
great effort to put it there

shrug Okay. Write a patch. Personally, I would prefer that it be a
function in cmath rather than a method because then it could be made to
work on integers and regular floats, too.
Ok, but what semantic should angle/arg have, say for 3 respectively
for 3.0?
the same as for arg(3+0j)?

Hello all,
I often have to deal with complex numbers
using python iteractive as calculator
I wonder why there are no methods like arg, abs
well one can use
c = 1+1j
abs(c)
In my opinion it would also be nice to have the
possibility to write it as
c.abs()
it looks more OO
unfortunately there
I would also like to see some more functions to make
calculations with complex number more convenient
e.g.
c = 27
c = 27+0j

I agree that this is a deficiency. I would think .angle() should be a

Hi Terry,

Python is object based but not rigidly OO in syntax or looks. This
is an
intentional design decision. Not being gratuitiously redundant is
another.
I agree, redundancy

c.arg(angle_mode = cmath.GRAD) - 45.0
Is that right? The result looks more like Degrees...
maybe I confuse, in german one would say 45 Grad
I took a freedom to translate it directly :)
well, my calculator shows a D
which most likely stands for Degree, I cannot tell for sure

Probably. In English, you have degrees and gradians, which aren't the
same thing;

I am aware of the usage of argument to mean the angle in polar
representation, but I don't like it. The word argument already has two
other meanings, one in common English, the other in math/CS. The latter
meaning is the inputs to a function, and that is how the word is used in
