Issue in converting to list from dictionary in python

Question

I have already converted my dictionary to a list but got stuck in getting in specific format. My output dictionary is,

foldersinlist = [['Training'], ['Training videos', 'Training documents', 'Training workouts', 'Training practicals', 'Training practicals', 'Training practicals']]

How I want is,

['Training', 'Training videos', 'Training documents', 'Training workouts', 'Training practicals', 'Training practicals', 'Training practicals']

The code which I currently have is below,

foldersinlist = list(folders.values())
print(foldersinlist)

Answer 1

Try:

print([x for i in foldersinlist for x in i])

Output:

['Training', 'Training videos', 'Training documents', 'Training workouts', 'Training practicals', 'Training practicals', 'Training practicals']

Answer 2

this is nested list and not dictionary:

foldersinlist = [['Training'], ['Training videos', 'Training documents', 'Training workouts', 'Training practicals', 'Training practicals', 'Training practicals']]

this is flat list:

['Training', 'Training videos', 'Training documents', 'Training workouts', 'Training practicals', 'Training practicals', 'Training practicals']

just do:

ll = sum(foldersinlist , [])
