A complex number has both real and imaginary parts, and Python allows you to specify this data type in a very easy and convenient way.

Syntax:

<variable name>=complex(x,y) 

OR

<variable name>=x+yj 

Here, x is the real part and y is the imaginary part. Here, j plays the role of iota.

It will be clearer with the following screenshot:

Here, we declare two variables to denote complex numbers. One way to achieve is to use complex() method and the other way is to use the standard notation as used in mathematics.
