1. Before you open the file, please make sure you have the correction permissions to read, write or create the file. Right click on the file or folder and check the attribute tab.

2. Use the open() method to open a file and create a file object:
myfile = open(“myfile.txt”)
This will open or create myfile.txt for reading and for writing.

3. Know that if you wish to open a file only for reading or only for writing, you can pass a second argument to open(). Pass ‘r’ for read only, ‘w’ for write only and ‘rw’ for explicit read-write. For example:
#open a file for read only
myfile = open(‘myfile.txt’, ‘r’)

4. Be sure to call the close() method to close any open file handles once you are done using the file, so that later processes can access the file:
myfile.close
