Complex() function in Python

Function Name:

complex

Function Signature:

class complex([real[, imag]])

Function Overview:

• The complex() function in Python is the constructor for the class complex and returns an object of type complex – representing complex numbers.
• A complex number is of the form x+iy. Where,
  • x is the real part.
  • y is the imaginary part.
  • i is the equivalent of a imaginary one – which satisfies i² = -1.
  • Both the real part and the imaginary part of a complex number are real numbers.

Parameters:

real – The real part of the complex number

imag – The imaginary part of the complex number

Note: A complex number can be constructed by passing a string of the form

“<RealPart>+<ImaginaryPart>j”, where RealPart and ImaginaryPart are real numbers.

E.g., “20-1j”, “-20+2j”

If the string format like the ones specified above are passed the second parameter should not be passed to the function complex().
