你好,以下是一个Python积分抽奖程序的示例代码,你可以根据自己的需求进行修改。这个程序使用了Python内置的random模块,可以实现从候选人名单中抽取一等奖和二等奖。在这个程序中,一等奖的中奖概率与积分成正比,二等奖的中奖概率均等。这个程序还使用了csv模块来读取和写入候选人名单。import csv
import random
def read_candidates():
candidates = []
with open('Candidates.csv', 'r') as f:
reader = csv.reader(f)
for row in reader:
candidates.append(row)
return candidates
def write_candidates(candidates):
with open('Candidates.csv', 'w', newline='') as f:
writer = csv.writer(f)
for row in candidates:
writer.writerow(row)
def read_updates():
updates = []
with open('updates.csv', 'r') as f:
reader = csv.reader(f)
for row in reader:
updates.append(row)
return updates
def write_updates(updates):
with open('updates.csv', 'w', newline='') as f:
writer = csv.writer(f)
for row in updates:
writer.writerow(row)
def get_lottery_result(candidates):
first_prize_candidates = [c for c in candidates if int(c[1]) >= 1000]
if len(first_prize_candidates) == 0:
return None
first_prize_probabilities = [int(c[1]) for c in first_prize_candidates]
first_prize_probabilities_sum = sum(first_prize_probabilities)
first_prize_probabilities_normalized = [p / first_prize_probabilities_sum for p in first_prize_probabilities]
first_prize_winner_index = random.choices(range(len(first_prize_candidates)), weights=first_prize_probabilities_normalized)[0]
first_prize_winner_id = first_prize_candidates[first_prize_winner_index][0]
second_prize_candidates = [c for c in candidates if int(c[1]) > 0 and c[0] != first_prize_winner_id]
if len(second_prize_candidates) < 2:
return None
second_prize_winner_ids = random.sample([c[0] for c in second_prize_candidates], k=2)
return (first_prize_winner_id, second_prize_winner_ids)
def run_lottery():
candidates = read_candidates()
updates = read_updates()
for update in updates:
candidate_index = next((i for i, c in enumerate(candidates) if c[0] == update[0]), None)
if candidate_index is None:
candidates.append([update[0], update[1]])
else:
candidates[candidate_index][1] = str(int(candidates[candidate_index][1]) + int(update[1]))
lottery_results = []
while True:
lottery_result = get_lottery_result(candidates)
if lottery_result is None:
break
lottery_results.append(lottery_result)
candidates = [c for c in candidates if c[0] not in lottery_result]
write_candidates(candidates)
print('一等奖:')
for result in lottery_results:
print(result[0])
print('二等奖:')
for result in lottery_results:
print(result[1][0])
print(result[1][1])
run_lottery()
