How to Read and Write Files in Python | File Handling Tutorial in Python

This is a tutorial video on how to read and write files in Python. This video covers all the basic concepts required to get started with file handling in Python. File objects in Python can be used to read the contents of a file and also file objects can be used to write or append data into a file.

In this video, we cover all the basic concepts required to get started with handing files in Python. We first look at how to read a file which is stored in our operating system. And then cover the concepts of how to write data into a file and also how to append data into a file.
We check out the different between using write and append in Python.

To open the file, we use context manager as well as the traditional method to open a file. We talk about the advantages of using context manager while opening a file in python and also explain why it is recommended in python to always use context manager when dealing with files.

In this video, we also talk about to how to read a file which is present in different paths or directories. By providing absolute path or relative path to the file we can tell python to look for the desired file in that specific location. However, we can also change the current working directory to point at the path where our desired file is placed.
If path is not mentioned, then Python always looks for the file in the current working directory. However, we can change the current working directory so as to point it to the location where our desired file is placed.
Alternatively, we can also provide the directory path of the file which we are trying to read. We can specify a path in two ways, one is by specifying the absolute path and second is by specifying the relative path.
In this video, we talk about relative and absolute path and also show how you can extract the current working directory and also how you can change the current working directory.

The statement `if line.startswith('Answer'):` works the same without the boolean declaration `is True`
