Computes the net amount of a bank account based a transaction log from console input In Python

Write a program that computes the net amount of a bank account based a transaction log from console input. The transaction log format is shown as following:

D 100

W 200

D means deposit while W means withdrawal.

Suppose the following input is supplied to the program:

D 300

D 300

W 200

D 100

Then, the output should be:

500

Hints:

In case of input data being supplied to the question, it should be assumed to be a console input.

Solution:

netAmount = 0

while True:

    s = raw_input()

    if not s:

        break

    values = s.split(" ")

    operation = values[0]

    amount = int(values[1])

    if operation=="D":

        netAmount+=amount

    elif operation=="W":

        netAmount-=amount

    else:

        pass

print netAmount
