Python提供了许多强大的内置函数,合理使用这些函数可以使代码更加简洁高效。 # Using sum() for summation total = sum([1, 2, 3, 4]) 五、工具和插件的使用 除了代码格式化工具,还有许多IDE和编辑器插件可以帮助保持代码整齐。 Visual Studio Code Visual Studio Code是一款流行的代码编辑器,支持多种语言的格式化。
def summation(nums): return sum(nums)def action(func, numbers): return func(numbers)print(action(summation, [1, 2, 3]))# Output is 6 或者更简单“返回函数”的例子：def rtnBrandon(): return "brandon"def rtnJohn(): return "john"def rtnPerson(): age = int(input("What'...
Create a function that calculates the summation of neighboring values for a given matrix entry, provided they are present. def sumNeighbors(M,x,y): l = [] for i in range(max(0,x-1),x+2): # max(0,x-1), such that no negative values in range() for j in range(max(0,y-1),...

summation = reduce(lambda x, y: x + y, numbers) 另外,Python中大量的内嵌功能可/会(我不知道这是好事还是坏事,你选一个,不加这个句子有点难懂)消耗迭代器: >>> a = list(range(10)) >>> a [0, 1, 2, 3, 4, 5, 6, 7, 8, 9] ...
