The cmath.exp() function calculates the value of e (Euler's number) raised to the power of x. Where is the input complex number.

cmath.exp(x)
x The value(real or complex) whose exponent value is to be calculated.

The exp() function returns the value of e raised to the power of the complex number x,. If the input numbers is a real number, it is first converted to complex before the operation. The return value is always a complex number.

import cmath

print(cmath.exp(2))
print(cmath.exp(complex(2, -1))) 
print(cmath.exp(1 + 2j))
print(cmath.exp(3 + 5j))
