Python variables do not need explicit declaration to reserve memory space. The declaration happens automatically when you assign a value to a variable. The equal sign (=) is used to assign values to variables.
1.3. Python Complex Type Complex number in python is made up of two floating point values, one each for real and imaginary part. For accessing different parts of variable (object)x; we will usex.realandx.image. Imaginary part of the number is represented byjinstead ofi, so1+0jdenotes zer...

In Python, a variable is declared and assigned a value using the assignment operator =. The variable is on the left-hand side of the operator, and the value being assigned—which can be an expression such as 2 + 2 and can even include other variables—is on the right-hand side. For ...
