I've re-formatted your code to improve readability and consistency. Some changes include:

1. Using consistent variable naming conventions (snake\_case).
2. Breaking long lines into multiple lines for better readability.
3. Adding a few blank lines to separate functions and logical blocks of code.
4. Reordering imports alphabetically.
5. Using f-string literals for formatting strings.

Here's the improved version of your code:

가독성과 일관성을 개선하기 위해 코드 형식을 다시 지정했습니다. 일부 변경 사항은 다음과 같습니다:1. 일관된 변수 명명 규칙(snake\_case) 사용.2. 가독성을 높이기 위해 긴 줄을 여러 줄로 나누었습니다.3. 함수와 논리적 코드 블록을 구분하기 위해 빈 줄을 몇 개 추가합니다.4. 가져오기 순서를 알파벳순으로 재정렬하기.5. 문자열 서식 지정에 f-스트링 리터럴 사용.개선된 코드 버전은 다음과 같습니다:'''python에서 임포트 보조, 비_시프트가능, 시프트가능클래스에서 임포트 Applianceimport mathprices = {    0: 0.17043824334020852,    1: 0.17687964847282173,    2: 0.1848716150231699,    3: 0.16119955296182936,    4: 0.16220396601978404,    5: 0.17861609773844922,    6: 0.19649085997831328,    7: 0.36008332379269636,    8: 0.396606737372287,    9: 0.5501378614431885,    10: 0.5940889787258893,    11: 0.18848951740313521,    12: 0.18571010112349637,    13: 0.16788191713340134,    14: 0.1709039894099174,    15: 0.16532830213734045,    16: 0.4565517132282808,    17: 0.5857373298786244,    18: 0.3656057042514985,    19: 0.49303826836168463,    20: 0.38306623023534225,    21: 0.43242741485567326,    22: 0.1580491724358629,    23: 0.17048220206057746}def estimate_electricity_cost_for_run(시간: int, 기간: int, 소비량: int) -> int:    글로벌 가격    cost = 0    for i in range(hour, hour + duration):        if i >= 24:            i -= 24        cost += prices[i] * (소비 / 기간)    비용 반환def estimate_best_hour_start(duration: int, min_hour: int, max_hour: int, consumes: int) -> int:    글로벌 가격    min_cost = -1    min_index = -1    if max_hour < min_hour:        max_hour += 24    범위(min_hour, max_hour - duration)의 시간에 대해:        if hour >= 24:            hour -= 24        cost = estimate_electricity_cost_for_run(시간, 기간, 소비량)        cost < min_cost 또는 min_cost == -1:            min_cost = 비용            min_index = 시간    반환 min_indexdef optimal_calculation(appliances):    schedule = {i: [] for i in range(24)}    어플라이언스에서 어플라이언스의 경우:        if not appliance.shiftable 또는 ((appliance.time_start + appliance.duration) % 24) == appliance.time_stop % 24:            schedule[appliance.time_start].append(appliance)            계속        hour_start = estimate_best_hour_start(            appliance.duration, appliance.time_start, appliance.time_stop, appliance.consumption)        schedule[hour_start].append(appliance)    반환 일정```
