# Write a Python 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 (Withdrawal is not allowed if balance is going negative. Write functions for 
# withdraw and deposit) 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
