Exception handling Introduction to exception handling, handling exceptions using try-except-finally blocks

File handling Introduction to files, types of files, relative and absolute paths

Text file: opening a text file, text file open modes, closing a text file, opening a file using with clause, writing/appending data to a text file using write() and writelines() functions, reading from a text file using read(), readline() and readlines() functions, seek() and tell() functions, manipulation of data in a text file

Binary file: open using file open modes, close a binary file, import pickle module, dump() and load() method, read, write/create, search,append and update operations

CSV file: import csv module, open / close csv file, write into a csv file using writer(), writerow() and writerows(), reading from csv file using reader( )
