字符串包含列表的所有元素 [英] String contains all the elements of a list

问题描述

我正在转向Python，但对于pythonic方法来说还是一个相对较新的事物.我想编写一个函数，该函数接受一个字符串和一个列表，如果列表中的所有元素都出现在字符串中，则返回true.

I am shifting to Python, and am still relatively new to the pythonic approach. I want to write a function that takes a string and a list and returns true if all the elements in the list occur in the string.

这似乎很简单.但是，我面临一些困难.代码是这样的:

This seemed fairly simple. However, I am facing some difficulties with it. The code goes something like this:

def myfun(str,list):
   for a in list:
      if not a in str:
         return False
      return True

---

Example : myfun('tomato',['t','o','m','a']) should return true
          myfun('potato',['t','o','m','a']) should return false
          myfun('tomato',['t','o','m']) should return true

---

此外，我希望有人可以在这里建议一种可能的正则表达式方法.我也在尝试用手.

---

Also, I was hoping if someone could suggest a possible regex approach here. I am trying out my hands on them too.

推荐答案

>>> all(x in 'tomato' for x in ['t','o','m','a'])
True
>>> all(x in 'potato' for x in ['t','o','m','a'])
False
