In the post I will show how to create a File, Write, read and append in python.

Before that lets see the File Modes in Python

File Modes in Python
Mode	Description
'r'	Open a file for reading. (by default)
'w'	Open a file for writing. Creates a new file if it does not exist or deleates the file if it exists.
'x'	Open a file for exclusive creation. If the file already exists, the operation fails.
'a'	Open for appending at the end of the file without replacing it. Creates a new file if it does not exist.
't'	Open in text mode. (by default)
'b'	Open in binary mode.
