如何检查子列表中的所有项目是否都在列表中?Python [英] How to check if all items in a sub-list are in a list? Python

问题描述

我的问题与上面的差不多:

my question is pretty much as above:

如果您有以下两个列表，如何检查第一个列表中的所有项目是否都在第二个列表中.例如

if you have 2 lists as below, how can you check if all items in the first list are in the second list. eg

list_one=[1,2,3]
list_two=[1,2,3,4]

我当前的尝试只是如果list_two中的所有list_one:"

my current attempt is just "if all list_one in list_two:"

但是这种情况似乎从未得到满足，因此没有任何进一步发生.任何帮助将不胜感激，谢谢:)

but this condition never seems to be filled and so nothing further takes place. Any help would be appreciated thanks :)

推荐答案

all()函数用于检查是否满足所有条件.我们从list_1获取元素，并检查是否满足条件如果全部可用，则在list_2中可用，然后我们打印是"

The all() function is used to check if all the condition are satisfied .We are getting elements from list_1 and checking if that is available in list_2 if all are available then we print "yes"

list_one=[1,2,3] 
list_two=[1,2,3,4]
if all(a in list_two for a in list_one):
    print "yes"
