How to Remove Characters from Strings in Python: Shifting vs. New String Creation?

Stripping Characters from Strings in Python: An Exploration

Python strings are immutable, meaning they cannot be altered directly. Therefore, to delete a character from a string, you must construct a new string.

Char Removal Techniques

There are two primary approaches to remove characters from strings:

1. Shifting: This involves shifting all characters to the left or right, starting from the character to be removed, effectively overwriting it.
2. New String Creation: This involves creating a new string without copying the character to be deleted.

Middle Character Removal

To remove the middle character from a string, such as "EXAMPLE", the second approach is generally more efficient. The following code snippet demonstrates this:

<code class="python">mid_len = len("EXAMPLE") // 2  # Find the index of the middle character
new_str = "EXAMPLE"[:mid_len] + "EXAMPLE"[mid_len + 1:]  # Create new string without the middle character</code>

Special Character Consideration

In Python, strings do not end with a special character. Unlike C-style strings that terminate with the null character '
