Note: If the first parameter that passed is a string then the second parameter shouldn’t be passed else will raise a TypeError. The string must not contain whitespace around the + or – operator else it will raise ValueError in Python.

Python complex() function returns a complex number ( real + imaginary) example (5+2j) when real and imaginary parts are passed, or it also converts a string to a complex number.
