Learn how to calculate the average of a set of numbers in Python. This program demonstrates how to iterate through a list of numbers, calculate the sum, and divide by the total number of elements to find the average. Follow along with the code and try it
A weighted average is an average in which some of the items to be averaged are 'more important' or 'less important' than some of the others. The weights are (non-negative) numbers which measure the relative importance For example, the weighted average of a list of numbers x1,…,xnwith ...
编写一个Python函数,接收一个整数列表作为参数,返回列表中所有偶数的平均值。```pythondef average_even(numbers):evens = [x for x in numbers if x % 2 == 0]if len(evens) == 0:return 0return sum(evens) / len(evens)numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]print(a

上下文管理器对象存在以控制with语句,就像迭代器存在以控制for语句一样。 with语句旨在简化一些常见的try/finally用法,它保证在代码块结束后执行某些操作,即使代码块由return、异常或sys.exit()调用终止。finally子句中的代码通常释放关键资源或恢复一些临时更改的先前状态。
