在Python中压缩多个条件 [英] Compressing multiple conditions in Python

问题描述

假设我有一个数字列表 mylist ，并且如果 mylist 的所有元素都大于10，我想执行一些代码.我可以尝试

Suppose I have a list of numbers mylist and that I would like execute some code if all the elements of mylist are greater than 10. I might try

if mylist[0] > 10 and mylist[1] > 10 and ... :
    do something

但这显然很麻烦.我想知道Python是否可以在if语句中压缩多个条件.我尝试过

but this is obviously very cumbersome. I was wondering if Python has a way of compressing multiple conditions in an if statement. I tried

if mylist[i] > 10 for i in range(len(mylist)):
    do something

但是这返回了一个错误.

but this returned an error.

我正在使用Python 3.4.

推荐答案

您的尝试非常接近.您只需要 all 函数来检查表达式的结果.

Your attempt is pretty close. You just needed the all function to examine the results of the expression.

if all(mylist[i] > 10 for i in range(len(mylist))):
    do something

顺便说一句，考虑直接遍历列表中的项目，而不是遍历其索引.

Incidentally, consider iterating over the items of the list directly, rather than its indices.

if all(item > 10 for item in mylist):
