Writing Files with Open

 You can also write to files using the open() function in Python. Here's how:

Use Python's open() function to obtain a file object for creating a text file. Provide the file path (including the file name) as the first argument. If the file already exists, it will be overwritten. Set the mode parameter to 'w' for writing.

Use the with statement to automatically close the file after writing. This ensures that resources are freed up properly.

Write data to the file using the write() method. Each call to write() will add data to the file. Successive calls will append data to the existing content.

You can also write each element in a list to a file. Iterate over the list and write each element to the file.

You can set the mode to append using lowercase 'a'. This will add data to the existing file without overwriting it.

To copy one file to a new file, first read the contents of the original file using a file object. Then create a new file and write the contents of the original file to it.

Close both files after reading from and writing to them.

Here's a summary of the steps involved in writing to files using the open() function:

Open a file for writing using open() with mode 'w'.

Write data to the file using the write() method.

Close the file using close().

Optionally, use the with statement to ensure proper resource management and automatic file closure.
