Find All Character Positions in a String with Python

This Python code demonstrates how to find all positions of a specific character within a string. It uses the find() method inside a while loop.

• The string fruits = 'apple and banana' is defined, and the target character is 'a'.
• The variable index acts as the starting point for the search and is initially set to 0.
• In each iteration, find() returns the first index of the character from the current index.
• If find() returns -1, the character is not found, and the loop breaks.
• Otherwise, the found index is added to the positions list, and the index is incremented by 1 to continue the search after that position.

Finally, the list of positions is printed. This approach is useful for finding all occurrences of a pattern in a string efficiently.
