This will create a new dictionary called new_dict that contains all the key-value pairs from my_dict except for the one with the key 'key2'. Conclusion In this article, we explored how to remove elements from a Python dictionary using the pop() method, the del statement, and dictionary...
Output:In this Python string, the hyphen is at the5th position(remember, Python uses 0-based indexing). To remove the hyphen, we can take all characters before it and all characters after it, then concatenate them together. By concatenating these two substrings, we effectively remove the hyph...
