python - How to find string from a list of strings with a specific list of characters?

Question

I have a given list of string and a list of characters and I want to check the string with containing a specific character. Here is an example:

Dictionary = ["Hello", "Hi"]
Character = ['e','i']

it must return a "Hello" else empty list

I am comparing a list of characters with a list of strings but it is giving me a type error.

Dictionary = ["Hello", "Hi"]
Character = ['e']
emptystring = ""
def findwords(dictionary,character):
   for i in dictionary,character:
      for j in dictionary:
          if character[i] == dictionary[i][j]:
             return dictionary[i]
          else:
             j+=1
    i+=1
return emptystring

k = findwords(Dictionary,Character)
k

TypeError                                 Traceback (most recent call last)

      2 k

----> 7             if str(character[i]) == str(dictionary[i][j]):
      8                 return str(dictionary[i])
      9             else:

TypeError: list indices must be integers or slices, not list

检查这个。

Dictionary = ["Hello", "Hi"]
Character = ['e']

def findwords(dictionary,character):
    tmp = ""
    for i in dictionary:
        #convert string to char list
        str_arr = list(i)
        for j in character:
            #if char is in char list then save it in tmp variable
            #if you want multiple values then use array instead of tmp
            if j in str_arr:
                tmp = i
    return tmp

k = findwords(Dictionary,Character)
print(k)
