当你这样做

for v in nested_group_map[group].values():
    v = v + 1

您没有以任何方式改变 nested_group_map。查看 this answer 以获得简要说明。为此，您必须使用密钥明确写入：

group_map = nested_group_map[group]
for k,v in group_map.items():
    group_map[k] = v + 1

这是@enzo 帮助下的完整答案。我也不得不删除 np.all() 出于任何原因我不能让它太工作。所以我在返回布尔值的 return sum(check_sum) == len(check_sum) * cycles 函数中使用了 cycle_checker 代替

cycles = 12

# data structure
nested_group_map = {
    'group_l1n' : {
    'shed_count': 0,},'group_l1s' : {
    'shed_count': 0,'group_l2n' : {
    'shed_count': 0,'group_l2s' : {
    'shed_count': 0,}
}


def cycle_checker(cycles):
    check_sum = [int(cycles)]
    #print(f'cycle_checker after for loop sum is {sum(check_sum)}')
    #print(f'cycle_checker appended after for loop is {check_sum}')

    for group in nested_group_map:
        for k,v in nested_group_map[group].items():
            if k in ('shed_count'):
                check_sum.append(int(v))
        
    #print(f'cycle_checker after for loop sum is {sum(check_sum)}')
    print(f'cycle_checker appended after for loop is {check_sum}')
    
    # returns boolean
    return sum(check_sum) == len(check_sum) * cycles


def run_another_cylce():
    for group in nested_group_map:
        group_map = nested_group_map[group]
        for k,v in group_map.items():
            group_map[k] = v + 1
            
            
while not cycle_checker(cycles):
    run_another_cylce()

这就是我希望看到的，基本上填满垃圾箱 (shed_count) 直到它们全部填满 cycles
