Replace Words in a List Based on Sublist in Python
How to replace words in a list based on a sublist in Python?
To replace words in a list based on a sublist in Python, you can use the following code snippet: ```python test_list = ['4', 'kg', 'butter', 'for', '40', 'bucks'] my_dict = [['butter', 'clutter'], ['four', 'for']] for i in range(len(test_list)): for sublist in my_dict: if test_list[i] in sublist: index = sublist.index(test_list[i]) test_list[i] = sublist[index + 1] break print(test_list) ``` The above code iterates over each word in the `test_list`. Then, for each word, it iterates over the sublists in `my_dict` and checks if the word is present in any sublist. If it is, it finds the index of the word in that sublist and replaces it with the next word in the same sublist. Finally, it prints the modified `test_list` with the replaced words.
Explanation:
1. Input Data:We have a `test_list` containing words like '4', 'kg', 'butter', 'for', '40', 'bucks', and a `my_dict` which is a list of sublists with word replacements like [['butter', 'clutter'], ['four', 'for']].
2. Loop Through Words:
We loop through each word in the `test_list` using a `for` loop.
3. Check in Sublists:
For each word in the `test_list`, we iterate over the sublists in `my_dict` and check if the word is present in any sublist.
4. Replace Words:
If a word is found in a sublist, we find the index of that word in the sublist and replace it with the next word in the same sublist.
5. Print Modified List:
Finally, we print the modified `test_list` with the replaced words.
This code snippet provides a method to replace words in a list based on a sublist in Python efficiently. It is a useful technique when you need to perform word replacements or manipulations in your data processing tasks.
