Python cmath - phase() Function
The Python cmath.phase() function returns the phase of a complex number x as a float. It is also known as the argument of x and equivalent to math.atan2(x.imag, x.real). The returned value lies in the range [-𝜋, 𝜋].
Syntax
cmath.phase(x)
Parameters
x |
Required. Specify the complex number in rectangular co-ordinates. |
Return Value
Returns the phase of a given complex number.
Example:
In the example below, phase() function is used to find out the phase of a given complex number.
import cmath x = 3 + 4j y = 3 z = 2j print(cmath.phase(x)) print(cmath.phase(y)) print(cmath.phase(z))
The output of the above code will be:
0.9272952180016122 0.0 1.5707963267948966
