Whenever i am defining a class and creating an instance of it ,, a TypeError is generated . why so ?

Try to change the name of your class, because python already define a type "complex" as the int, long, float, ...

Answer 2

Please provide sample of the code you used to create class and instance of it.

Answer 3

class complex:
def __init__(self,real,imag):
self.r=real
self.i=imag
x=complex(3,-4.5)

TypeError : this constructor takes no arguments
