In this tutorial we will learn Binary File Handling in Python

Types of File :-
Text File - Stores data in ASCII, UNICODE Format
Binary File - Stores data as in the format of the memory
CSV File - Stores Tabular Data separated by comma ','

Modes in File Handling :-
r: open an existing file for a read operation.
w: open an existing file for a write operation. If the file already contains some data then it will be overridden but if the file is not present then it creates the file as well.
a: open an existing file for append operation. It won’t override existing data.
r+: To read and write data into the file. The previous data in the file will be overridden.
w+: To write and read data. It will override existing data.
a+: To append and read data from the file. It won’t override existing data.

There are a special function for the heading row with the name of the columns?
When you are using writerow and writerows there are blank lines in between, any way to avoid it?
There is an option to append and destroy the old info?
We can add a row in any position of the rows?
Thank you!
