Difference Between R+ And W+ In Python
In Python, ‘r+’ and ‘w+’ are file modes used to open a file for reading and writing simultaneously. The main difference between ‘r+’ and ‘w+’ is how they handle the file pointer position. When using ‘r+’, the file pointer is initially positioned at the beginning of the file, and any read or write operations will take place at the current position of the file pointer. If the file does not exist, it will raise a FileNotFoundError. On the other hand, when using ‘w+’, the file pointer is initially positioned at the beginning of the file, but it will truncate the file to zero length if it already exists. This means that any existing content will be erased before any read or write operations take place. If the file does not exist, it will be created.

1 - Using ‘r+’ in Python:
‘r+’ mode in Python allows both reading and writing to a file.
When using ‘r+’ mode, the file pointer is positioned at the beginning of the file.
If the file does not exist, it will raise a FileNotFoundError.
When writing in ‘r+’ mode, the existing content of the file will be overwritten if the new content is shorter. If longer, it will overwrite the characters in the file.
2) Using ‘w+’ in Python:
‘w+’ mode in Python also allows reading and writing to a file like ‘r+’.
When using ‘w+’ mode, if the file exists, it truncates the file to zero length. If the file does not exist, it creates a new file.
The file pointer is positioned at the beginning of the file.
Writing in ‘w+’ mode will overwrite the existing content entirely with the new content provided.
‘w+’ also raises a FileNotFoundError if the file specified does not exist.
