How to split list based on values in Python? - list

Question

I have a list that needs to copied multiply times by the number at an index.
here is an example to help explain.
The original list:
[AAA, Bus, Apple, 5, 3, 1, Car, 22, 30]
what is needs to become:
aList = [
[AAA, Bus, Apple, 1, 1, 1, Car, 22, 30]
[AAA, Bus, Apple, 1, 1, 0, Car, 22, 30]
[AAA, Bus, Apple, 1, 1, 0, Car, 22, 30]
[AAA, Bus, Apple, 1, 0, 0, Car, 22, 30]
[AAA, Bus, Apple, 1, 0, 0, Car, 22, 30]
]
All the list are in the same order to I can view the values bu index.
Thanks

Answer 1

I hope I've understood your question right. This example will copy the list by maximal number found in list:
lst = ["AAA", "Bus", "Apple", 5, 3, 1, "Car"]
n = max((v for v in lst if isinstance(v, int)), default=0)
out = [lst]
for _ in range(n - 1):
out.append([(v - 1) if isinstance(v, int) else v for v in out[-1]])
out = [[int(v > 0) if isinstance(v, int) else v for v in l] for l in out]
print(*out, sep="\n")
Prints:
['AAA', 'Bus', 'Apple', 1, 1, 1, 'Car']
['AAA', 'Bus', 'Apple', 1, 1, 0, 'Car']
['AAA', 'Bus', 'Apple', 1, 1, 0, 'Car']
['AAA', 'Bus', 'Apple', 1, 0, 0, 'Car']
['AAA', 'Bus', 'Apple', 1, 0, 0, 'Car']
EDIT: To change only specified indices:
lst = ["AAA", "Bus", "Apple", 5, 3, 1, "Car"]
n = max(v for v in lst[3:6])
out = [lst[3:6]]
for _ in range(n - 1):
out.append([v - 1 for v in out[-1]])
out = [lst[:3] + [int(v > 0) for v in l] + lst[6:] for l in out]
print(*out, sep="\n")
Prints:
['AAA', 'Bus', 'Apple', 1, 1, 1, 'Car']
['AAA', 'Bus', 'Apple', 1, 1, 0, 'Car']
['AAA', 'Bus', 'Apple', 1, 1, 0, 'Car']
['AAA', 'Bus', 'Apple', 1, 0, 0, 'Car']
['AAA', 'Bus', 'Apple', 1, 0, 0, 'Car']
