Python provides various functions to perform different file operations, a process known as File Handling. Opening Files in Python In Python, we need to open a file first to perform any operations on it—we use the open() function to do so. Let's look at an example: Suppose we have a ...
Write mode ('w'): This mode is used to write to a file. It will create a new file if the file does not exist, and overwrite the file if it does exist. Append mode ('a'): This mode is used to add new data to the end of an existing file (append to a file). If the file...
