How print a list into separate lists python

Question

I have a list:

grades= ['doe john     100  90  80  90', 'miller sally  70  90  60 100  80', 'smith jakob   45  55  50  58', 'white jack    85  95  65  80  75']

I want to be able to break that list so the output would be:

['doe john     100  90  80  90']
['miller sally  70  90  60 100  80']
['smith jakob   45  55  50  58']
['white jack    85  95  65  80  75']

Additionally, I would like to split the elements in the list so it looks like:

['doe', 'john',     '100',  '90',  '80',  '90']
['miller', 'sally',  '70',  '90',  '60', '100',  '80']
['smith', 'jakob',   '45',  '55',  '50',  '58']
['white', 'jack',    '85',  '95',  '65',  '80',  '75']

I'm not really sure how to go about doing this or if this is even possible as I'm just starting to learn python. Any ideas?

Please show what you’ve tried so far and where you’re getting stuck. Hint, yes. It’s very possible and quite simple. Give it a try. — S3DEV, Apr 29 '20 at 22:20
I understand you want to make a list of lists, you can move from step1 to step3 in one line of code. Try to take a look to the ```split``` function — EnriqueBet, Apr 29 '20 at 22:21

for l in grades:
    l = l.split()

OR

final = [l.split() for l in grades]

This can be done quickly with .split() in a list comprehension.

grades = ['doe john     100  90  80  90', 'miller sally  70  90  60 100  80', 'smith jakob   45  55  50  58', 'white jack    85  95  65  80  75']

grades = [grade.split() for grade in grades]
print (grades)
