Example 1: python cmath methods

cmath.acos(x)	Returns the arc cosine value of x
cmath.acosh(x)	Returns the hyperbolic arc cosine of x
cmath.asin(x)	Returns the arc sine of x
cmath.asinh(x)	Returns the hyperbolic arc sine of x
cmath.atan(x)	Returns the arc tangent value of x
cmath.atanh(x)	Returns the hyperbolic arctangent value of x
cmath.cos(x)	Returns the cosine of x
cmath.cosh(x)	Returns the hyperbolic cosine of x
cmath.exp(x)	Returns the value of Ex, where E is Euler's number (approximately 2.718281...), and x is the number passed to it
cmath.isclose()	Checks whether two values are close, or not
cmath.isfinite(x)	Checks whether x is a finite number
cmath.isinf(x)	Check whether x is a positive or negative infinty
cmath.isnan(x)	Checks whether x is NaN (not a number)
cmath.log(x[, base])	Returns the logarithm of x to the base
cmath.log10(x)	Returns the base-10 logarithm of x
cmath.phase()	Return the phase of a complex number
cmath.polar()	Convert a complex number to polar coordinates
cmath.rect()	Convert polar coordinates to rectangular form
cmath.sin(x)	Returns the sine of x
cmath.sinh(x)	Returns the hyperbolic sine of x
cmath.sqrt(x)	Returns the square root of x
cmath.tan(x)	Returns the tangent of x
cmath.tanh(x)	Returns the hyperbolic tangent of x

Example 2: complex numbers python

c = 1 + 2j
print(type(c))
print(c)

c1 = complex(2, 4)
print(type(c1))
print(c1)

Example 3: abs of complex nos in python

abs(5j+9)  #square root of 5^2 +9^2

Example 4: how to take input complex number in python

complx = complex(input());
print(complx.real, complx.imag);
