Split Words By Separator

Here’s a Python function to split words using a separator and remove empty results:

class Solution(object):
    def splitWordsBySeparator(self, words, separator):
      ans = []
      for i in range(len(words)):  # Loop through each word inthe list
          ans.append(words[i].split(separator))  # Split wordby the separator

      new = sum(ans, [])  # Flatten the list (converts list oflists into a single list)
      res = list(filter(None, new))  # Remove empty stringsfrom the list

      return res  # Return the cleaned list of words

How It Works

• It takes two inputs:

words: A list of strings.
separator: A character used to split the words.

• It loops through each word and splits it using the separator.

• The split words are stored in a list (ans), which may contain sublists.

• It flattens ans using sum(ans, []) to merge all sublists into a single list.

• It removes empty strings using filter(None, new) to get rid of unnecessary empty elements.

• Finally, it returns the cleaned list of words.

Example

solution = Solution()
words = ["hello.world", "python.is.awesome", "split,this"]
separator = "."

result = solution.splitWordsBySeparator(words, separator)
print(result)

Output

['hello', 'world', 'python', 'is', 'awesome', 'split', 'this']
