Python: Calculate the maximum profit from selling and buying values of stock
Python Basic - 1: Exercise-74 with Solution
Write a Python program to calculate the maximum profit from selling and buying values of stock. An array of numbers represent the stock prices in chronological order.
For example, given [8, 10, 7, 5, 7, 15], the function will return 10, since the buying value of the stock is 5 dollars and sell value is 15 dollars.
def buy_and_sell(stock_price): max_profit_val, current_max_val = 0, 0 for price in reversed(stock_price): current_max_val = max(current_max_val, price) potential_profit = current_max_val - price max_profit_val = max(potential_profit, max_profit_val) return max_profit_val print(buy_and_sell([8, 10, 7, 5, 7, 15])) print(buy_and_sell([1, 2, 8, 1])) print(buy_and_sell())

x = [1, 2, 3] x.extend([4, 5]) print (x)
[1, 2, 3, 4, 5]
