有没有办法将7个随机变量限制为40个？
我想为 Fallout New Vegas 的 SPECIAL 统计数据制作一个随机数，我已经构建了大部分代码，但有些情况下变量的总和超过/低于 40 的上限。
有没有办法限制它们，或者在总和低于或超过 40 的情况下，分配差异？
strength = random.randint(1, 10)
perception = random.randint(1, 10)
endurance = random.randint(1, 10)
charisma = random.randint(1, 10)
intelligence = random.randint(1, 10)
agility = random.randint(1, 10)
luck = random.randint(1, 10)
sum = strength + perception + endurance + charisma + intelligence + agility + luck
diff = 40 - sum
if diff < 0:
diff = (diff * - 1)
print("=======================")
print("Strength:", strength)
print("Perception:", perception)
print("Endurance:", endurance)
print("Charisma:", charisma)
print("Intelligence:", intelligence)
print("Agility:", agility)
print("Luck:", luck)
print("Total:", sum)
print("Difference:", diff)
print("=======================")

生成七个小于 40 的数字，而不是生成七个独立的随机数，并使用它们的差异来生成您的统计数据。
import random
STATMAX = 10
# generate six random numbers, sorted, to use as dividers in the range
rand_numbers = sorted(random.choices(range(40), k=6))
# calculate stats by taking the differences between them
stat_numbers = [(j - i) for (i, j) in zip([0] + rand_numbers, rand_numbers + [40])]
# for values higher than 10, dump the excess values into other stats
excess_points = sum(max(s - STATMAX, 0) for s in stat_numbers)
# also, drop stats above 10 before redistributing the points
stat_numbers = [min(s, STATMAX) for s in stat_numbers]
while excess_points > 0:
idx = random.randint(0, len(stat_numbers) - 1)
# this approach favors balanced stats by only adding one point at a time
# an alternate approach would be to add as many points as possible, which
# would favor imbalanced stats (i.e. minmaxing)
if stat_numbers[idx] < STATMAX:
stat_numbers[idx] += 1
excess_points -= 1
strength, perception, endurance, charisma, intelligence, agility, luck = stat_numbers
您可以通过几种不同的方式来定制这种方法。例如，如果您希望滚动的总统计数据少于 40，则可以改为生成7 个随机数，并使用最后一个随机数而不是 40 作为端点。
