Python ListHelper.get_max Exemples

Exemple #1

#     获取具有生命值的对象总数
#     获取攻击速度小于２０的敌人总数
result = ListHelper.count(L, lambda enemy: enemy.hp > 0)
print(result)
result = ListHelper.count(L, lambda enemy: enemy.atk_speed < 20)
print(result)

# 解决的问题：判断列表中是否包含某个元素
#     获取列表中是否具有死人
#     获取列表中是否具有攻击速度大于１０的敌人
result = ListHelper.include(L, lambda enemy: enemy.hp == 0)
print(result)
result = ListHelper.include(L, lambda enemy: enemy.atk_speed > 10)
print(result)

#删除所有死人
# ListHelper.del_all(L,lambda enemy : enemy.hp == 0)
# print(L)
#删除编号是101的敌人
# ListHelper.del_all(L,lambda enemy : enemy.id == 101)
# print(L)

#获取血量最大的敌人
result = ListHelper.get_max(L, lambda enemy: enemy.atk_speed)
print(result)

print(L)
ListHelper.order_by(L, lambda enemy: enemy.atk_speed)
print(L)
ListHelper.order_by_descending(L, lambda enemy: enemy.atk_speed)
print(L)

Exemple #2

#
# for item in ListHelper.find_all(list01, lambda e: e.id > 102):
#     print(item.id)

# 2. map 映射，类似于ListHelper.select
# 映射出所有敌人的姓名
for item in map(lambda e: e.name, list01):
    print(item)

for item in ListHelper.select(list01, lambda e: e.name):
    print(item)

# # 按照血量升序排列,类似于ListHelper.order_by
# for item in sorted(list01,key = lambda e:e.hp ):
#     print(item.hp)
#
# # 按照血量降叙排列
# for item in sorted(list01,key = lambda e:e.hp,reverse=True):
#     print(item.hp)

# ListHelper.order_by(list01,lambda e:e.hp)
# for item in list01:
#     print(item.hp)

# 获取攻击力最大的敌人
result = max(list01, key=lambda e: e.atk)
print(result.name)

result = ListHelper.get_max(list01, lambda e: e.atk)
print(result.name)

Exemple #3

# 获取血量最大的敌人
# 获取攻击力最强的
# ...

# def demo01(target):
#     max_value = target[0]
#     for i in range(1, len(target)):
#         # if max_value.hp < target[i].hp:
#         if xxx(max_value) < xxx(target[i]):
#             max_value = target[i]
#     return max_value
#
# def xxx(item):
#     return item.hp

max = ListHelper.get_max(list01, lambda e: e.hp)
print(max.name)

# 练习：14:45
# 解决的问题：根据指定条件升序排列列表
# 按照血量升序排列
# 按照攻击力升序排列
# def demo01(target):
#     for r in range(len(target)-1):
#         for c in range(r+1,len(target)):
#             # if target[r].hp > target[c].hp:
#             if xxx(target[r]) > xxx(target[c]):
#                 target[r],target[c] = target[c],target[r]
#
# def demo02(target):
#     for r in range(len(target)-1):
