Hi Anand,

Your feedback reflects a common point of view on the surprising
difficulty of producing nicely formatted messages from Python code. As
such, it currently appears likely that Python 3.6 will allow you and
your peers to write output messages like this:

    print(f"Hello, I am {b}. My favorite number is {a}.")

as a simpler alternative to the current options:

    print("Hello, I am ", b, ". My favorite number is ", a, ".", sep="")
    print("Hello, I am " + b + ". My favorite number is " + str(a) + ".")
    print("Hello, I am {}. My favorite number is {}.".format(b, a))
    print("Hello, I am {b}. My favorite number is {a}.".format_map(locals()))
    print("Hello, I am %s. My favorite number is %s." % (b, a))

Regards,
Nick.
