## starters
x = [ 1, 2, 3, 4, 5 , 6, 7 ]
print(f'{x} => {xyz(x)}')'

x = [ 1, 2, 3, 4, 5 , 6, 7 ]
print(f'{x} => {xyz(x, len(x))}')
   
x, y = 'foo', 2
print(f'{x},{y} => {xxxxx(x, y)}')

    
## debug
print(repr(arr))
print(f'{x} => {xyz(x)}')

## string manipulation
arr = list(map(int, '1 2 3 4 5'.strip().split()))



## lists
arr.sort()
create an empty list of size n:  result = [0] * 100
unpacking *

## arr
x = [
  [ 1, 2, 3],
  [ 4, 5, 6],
  [ 9, 8, 9],
]
