Iam done with the command line parsing but got stuck while trying to
implement switch kind of behavior with dictionaries. So posting 2 more
questions
Question 1 :
Iam using the options.name directly for manipulations is this fine or do
I need to assign it to variable and then use it
Example:
Entered at cli #python corrupt.py -object_type INODE --path_name/ifs/1.txt
-operation_type SET
Initialize all the command line option and then use it
object_type = options.object_type
path_name = options.path_name
if object_type == 'LIN':
corrupt_inode()
elif object_type == 'DATA':
corrupt_data()
OR
if options.object_type == 'LIN':
corrupt_inode()
elif options.object_type == 'DATA':
corrupt_data()
elif options.object_type == 'INODE':
corrupt_data()
#output
#python corrupt.py -object_type INODE -p /ifs/1.txt -q SET -f 10
-m 10 -n 123 -l -c
Corrupted inode

Question 2 :
I wanted to use dictionary to match the above if else behavior (we don't
have switch in python I guess ) and If else looks very untidy.
Is it possible to store the options.object_type as a key in the dictionary
and then based on the value entered in the command line invoke the
appropriate function
I tried creating a dictionary like this but Iam getting a wrong output
object_type_dictonary = { 'LIN' : corrupt_inode(),
'INODE' : corrupt_lin(),
'DATA' : corrupt_data(),
};
and then ran # python corrupt.py -object_type= inode ( This prints all
the values for me)
Example :
Corrupted inode
Corrupted LIN
Corrupted data
PS : If user enters object_type= inode it should execute corrupt_inode
and print corrupted inode
Any help on tips highly helpful :)
