1. Ultimate Reference to Python File Methods
Python language provides a list of built-in file methods that work on files. In this tutorial, we will provide you with all the file methods or functions in alphabetical order. Further, these methods are also called file functions, but these rely only on their parent class. Usually, these methods are built-in in Python programming language and we can use them to work with files as required. The table below contains all the built-in file methods in this language and serves as an ultimate and up-to-date guide or reference.
2. Search Ultimate Reference For Python File Methods
Search Python file methods from the below table, which is an ultimate and up-to-date guide or reference, for the developers. Please note that the parameters or arguments of some methods might be optional, so don't worry while writing your Python programs.
2.1. Alphabetical Reference
| Method | Description |
| close() | Use this Python method to close the file. |
| detatch() | This Python method is used to return the separated raw stream from the buffer. |
| fileno() | This Python method returns a number that represents the stream from the operating system's perspective. |
| flush() | To flush the internal buffer, we use this Python method. |
| isatty() | To find out if the file stream is interactive or not, we use this Python method. |
| read() | This Python method returns the contents of the file. |
| readable() | This Python method returns whether the file stream is readable or not. |
| readline() | Use this Python method to return one line from the file. |
| readlines() | Use this Python method to return a list of lines from the file. |
| seek() | To change the file position, use this Python method. |
| seekable() | To know if we can alter the file position or not, use this Python method. |
| tell() | This Python method returns the current file position. |
| truncate() | To resize the file to a specified size, we use this Python method. |
| writable() | To know if we can write to a file or not, we use this Python method. |
| write() | This Python method is used to write a specified string to the file. |
| writelines | To write a list of lines to the file, we use this Python method. |
3. Dynamically Get Python File Methods
The Python language pack contains all the built-in methods to apply on files and fortunately, we can retrieve that list dynamically from the distribution. Use the following code to acquire the up-to-date and ultimate list of Python file methods.
Get All File Methods
# Get the list of file methods
import io
file_methods = [
method for method in dir(io.IOBase)
if callable(getattr(io.IOBase, method))
and not method.startswith('_')
]
# Print the list of file methods
filtered_file_methods = [method for method in file_methods]
print(filtered_file_methods)
Note:
Importantly, it is important to note that these methods are different from those of built-in Python functions, so make sure to keep this in mind.
4. Reference Links
In this reference tutorial, we collected resources and material from the below websites to write up a clear, up-to-date, and ultimate guide to Python file methods or functions that depend on specific classes.
- We explored W3schools.com as a reference to build up this ultimate guide of all Python file methods or class-dependent functions.
- Also, we consulted Python's official reference to finalize our list of file methods or class-dependent functions.
