[Nageshbansal]

display_all_rdatasets_names takes list of package_name insted of taking a string of package_name as a parameter

>>> display_all_rdataset_names("aer")
List of all available Rdatasets in packages: aer
No package named 'a' found in Rdatasets
No package named 'e' found in Rdatasets
No package named 'r' found in Rdatasets

>>> display_all_rdataset_names(["aer"])
List of all available Rdatasets in packages: ['aer']

At line 171, we're iterating over package_name, so I added a check if the given parameter package_name is a string, then we will convert it into a list, and if package_name is a list or a tuple, we don't need to correct them.

         print(f"List of all available Rdatasets in packages: {package_name}")
 ->     if type(package_name) == str:
 ->         package_name = list(package_name.split(' '))  
         for package in package_name:

Input :  
       package_name = 'aer'
output: 
List of all available Rdatasets in packages: aer
Package: aer              Dataset: affairs                   Script Name: rdataset-aer-affairs
.....

Input :  
       package_name = ['aer']
output: 
List of all available Rdatasets in packages: ['aer']
Package: aer              Dataset: affairs                   Script Name: rdataset-aer-affairs
