python3.x中cmp函數(shù)去掉了，如果需要實現(xiàn)比較功能，那么可引入operator 模塊 import operator
print(operator.lt(3,4) ==>True
print(operator.lt(3,4) ==>True

result = template.format(w=w , c=c , b=b, i=i )這一行要這樣寫，w=w，第一個w指template = 'Hello {w}, Hello {c}, Hello , Hello {i}.'這里定義的形參，第二個指 w = 'World'這里定義的實參學了函數(shù)就知道了這個報錯就是編譯器找不到你定義的實參

if not isinstance(x, int) or not isinstance(x, float)：
這段代碼應該使用邏輯運算符 and 而不是 or。這樣，只有當 x 既不是整數(shù)也不是浮點數(shù)時，才會打印錯誤信息并返回 None

首先是循環(huán)哪里的冒號是中文冒號，第二是你的循環(huán)是從列表L里面拿取元素的，你代碼里的列表直接寫在輸出函數(shù)，沒起任何作用翻譯搜索復制
