Python清单:检查所有项目是否相同 [英] Python list: check if all items are the same or not

问题描述

我有一个python字符串列表，想检查所有列表项值是否相同.

I have a python list of strings and want to check if all list item values are the same or not.

我尝试使用条件if/then，但随后我需要检查列表值的所有组合，并且如果列表中有很多项，则需要很多硬代码.

I tried to use condition if/then but then I'd need to check all combinations of list values and if list have many items then need to many hard code.

if item1 != item1 and item1 != item2 and item1 !=item2 ....... :
    check='wrong'
else:
    check= 'correct'

输入:

listOfStrings = ['ep:1000' , 'ep:4444', 'ep:1000', 'ep:1000', 'ep:1000', 'ep:1000']

更新

示例:

CORRECT_LIST = ['ep:1000' , 'ep:1000', 'ep:1000', 'ep:1000', 'ep:1000', 'ep:1000']

在正确的列表中，所有项目的值都相同，那么我的列表是正确的

IN correct list all items values are the same, then my list is correct

WRONG_LIST = ['ep:1000' , 'ep:4444', 'ep:1000', 'ep:1000', 'ep:1000', 'ep:1000']

错误列表中的WRONG_LIST并非所有项目的值字符串都是一些

WRONG_LIST in the wrong list is not all items values string are the some

推荐答案

这会将列表中的每个元素与第一个元素进行比较:

This compares every element of the list to the first one:

listOfStrings = ['ep:1000' , 'ep:4444', 'ep:1000', 'ep:1000', 'ep:1000', 'ep:1000']
check = all(x == listOfStrings[0] for x in listOfStrings)

并为测试用例返回false.
