sure! here is a beginner-friendly tutorial on python file handling.
python provides built-in functions and modules for working with files. file handling allows you to read from and write to files on your computer. this can be useful for storing data, reading configuration files, logging information, and much more.
1. opening a file:
to open a file in python, you can use the `open()` function. the `open()` function takes two arguments - the file path and the mode in which you want to open the file (read, write, append, etc.).
2. reading from a file:
you can read the contents of a file using the `read()` method. this method reads the entire file contents as a string.
3. writing to a file:
to write to a file, you can open the file in write mode (`"w"`) or append mode (`"a"`) and use the `write()` method to write to the file.
4. closing a file:
it is good practice to close a file after you are done working with it. you can close a file using the `close()` method.
5. using `with` statement:
to ensure that a file is properly closed after its suite finishes, you can use the `with` statement. this will automatically close the file for you.
remember to handle exceptions when working with files, such as `filenotfounderror` or `permissionerror`.
here is a simple example that reads from a file and prints its content:
