Numbers in lists by SeanMc from forums
define a procedure that takes in a string of numbers from 1-9 and
outputs a list with the following parameters:
Every number in the string should be inserted into the list.
If a number x in the string is less than or equal
to the preceding number y, the number x should be inserted
into a sublist. Continue adding the following numbers to the
sublist until reaching a number z that
is greater than the number y.
Then add this number z to the normal list and continue.
Hint - "int()" turns a string's element into a number
string = '543987'
numbers = int(string)
print numbers + 1
def numbers_in_lists(string):
m = 0
lista = []
lista2 = []
for i in range(len(string)):
number = int(string[i])
if number > m:
m = number
lista.append(number)
else:
m = number
lista2.append(number)
lista.append(lista2)
print lista
testcases
string = '543987'
result = [5,[4,3],9,[8,7]]
print repr(string), numbers_in_lists(string) == result
string= '987654321'
result = [9,[8,7,6,5,4,3,2,1]]
print repr(string), numbers_in_lists(string) == result
string = '455532123266'
result = [4, 5, [5, 5, 3, 2, 1, 2, 3, 2], 6, [6]]
print repr(string), numbers_in_lists(string) == result
string = '123456789'
result = [1, 2, 3, 4, 5, 6, 7, 8, 9]
print repr(string), numbers_in_lists(string) == result
