Trying Comparison Operators

[PythonGainz]

Good morrow, guys!

Used this code from a textbook and can't find the error. It seems like something at the beginning already, but I cant figure it out.

Code:

i=10
j=15
if(i==j):
    print("i is equal j")
    else:
    print("i is not equal to j")
    if(i!=i):
        print("i is not equal to j")
        else:
            print("i is equal to j")
            if(i>j)
            print("i is greater than j")
            else:
                print("i is not greater than j")
                if(i<j)
                print("i is less than j")
                if(i>=j)
                print("i is greater than or equal to j")
                else:
                    print("i is neither greater than nor equal to j")
                    if(i<=j)
                    print("i is less than or equal to j")
                    else:
                        print("i is neither less than or equal to j")

Many thanks everyone!
