A complex number is of the form

 ‘a’ and ‘b’ contain Integers OR Floating-Point Values.

Eg: 3 + 5j 10 + 5.5j 0.5 + 0.1j

 In the real part if we use an int value then we can specify that either by decimal, octal, binary, or hexadecimal form.  But the imaginary part should be specified only by using the decimal form. 1) >>> a=0B11+5j 2) >>> a 3) (3+5j) 4) >>> a=3+0B11j 5) SyntaxError: invalid syntax  Even we can perform operations on complex type values. 1) >>> a=10+1.5j 2) >>> b=20+2.5j 3) >>> c=a+b 4) >>> print(c) a + bj

Real Part Imaginary Part j2 = -1 j =

5) (30+4j) 6) >>> type(c) 7) Note: Complex data type has some inbuilt attributes to retrieve the real part and imaginary part

c = 10.5+3.6j

c.real  10.5 c.imag  3.6

We can use complex types generally in scientific Applications and electrical engineering Applications.
