output_list = []
a = [[10,40,90],[120,30,200],[70,90,100]]
for array in a:
counter = 0
new_list = []
while counter < len(array):
if array[counter] > 50:
new_list.append(counter)
counter += 1
output_list.append(new_list)
print(output_list)
輸出（根據(jù)需要）：
[[2], [0, 2], [0, 1, 2]]

index_of_values_greater_than_50 = []
for x in a:
temp = [i for i, y in enumerate(x) if (y>50)
index_of_values_greater_than_50.append(temp)
