Python sort list of list containing integer and string with integers inside

Question

How i can use python to sort the list format

format=[\"12 sheet\",\"4 sheet\",\"48 sheet\",\"6 sheet\", \"busrear\", \"phonebox\",\"train\"]

<

Answer 1

The same solution can be used here

print sorted(format_data, key=lambda x: (int(x[1].split(None, 1)[0]) if x[1][:1].isdigit() else 999, x))

Note the x[1] instead of just x. x[1] means the second element in x.

Result:

[[2, '4 sheet', 0],
 [4, '6 sheet', 0],
 [1, '12 sheet', 0],
 [3, '48 sheet', 0],
 [5, 'Busrear', 0],
 [6, 'phonebox', 0],
 [7, 'train', 0]]
