Here, I have one doubt regarding the get_data function that should the get_data function be a common function for different features for example : 
def _get_data(self, func_option):
 """
 A separate function for extracting data from the runpip() function.
 It is done in order to get this function tested using unittest module
 According to func_option, it returns the data extracted :
 Options:
 -------
 1. list : for listing all currently installed packages
 2. show <package name> : show details of installed packages
 3. search <keyword> : show formated search results
 4. install <package name> : get results while installing packages
 """
 splitted_options = func_option.split()
 if splitted_options[0] == 'list':
 return runpip(func_option)
 elif splitted_options[0] == 'show':
 return runpip(func_option)
 elif splitted_options[0] == 'search':
 return runpip(func_option)
 elif splitted_options[0] == 'install':
 return runpip(func_option)
I am not clear would this single function for retrieving data would be good for uniitest or different functions would be good for retrieving data.
