我是python和编程的新手,所以非常感谢你对这一点的任何澄清.
例如,在以下代码中:
#Using a class
class Monster(object):
def __init__(self, level, damage, duration):
print self
self.level = level
self.damage = damage
self.duration = duration
def fight(self):
print self
print "The monster's level is ", self.level
print "The monster's damage is ", self.damage
print "The attack duration is ", self.duration
def sleep(self):
print "The monster is tired and decides to rest."
x = Monster(1, 2, 3)
y = Monster(2, 3, 4)
x.fight()
y.fight()
y.sleep()
#just using a function
def fight_func(level, damage, duration): …这是一个用户可以输入像"冰茶"这样的值的游戏.我想操纵字符串返回"冰茶"而没有拖尾标点符号.
寻找最优雅/最简单的python解决方案.
试着
def last_character(word):
if word.endswith('.' or ','):
word = word[:-1]
return word
如果最后只有一个标点符号,则有效.但它并非包罗万象.
找到了Java解决方案:
String resultString = subjectString.replaceAll("([a-z]+)[?:!.,;]*", "$1");
请帮我理解这个.我创建了一个非常简单的程序来尝试理解类.
class One(object):
def __init__(self, class2):
self.name = 'Amy'
self.age = 21
self.class2 = class2
def greeting(self):
self.name = raw_input("What is your name?: ")
print 'hi %s' % self.name
def birthday(self):
self.age = int(raw_input("What is your age?: "))
print self.age
def buy(self):
print 'You buy ', self.class2.name
class Two(object):
def __init__(self):
self.name = 'Polly'
self.gender = 'female'
def name(self):
self.gender = raw_input("Is she male or female? ")
if self.gender == 'male'.lower():
self.gender = 'male'
else:
self.gender = 'female'
self.name = …关于SO的类似问题包括:这个和这个.我还阅读了我能找到的所有在线文档,但我仍然很困惑.我很感激你的帮助.
我想在CastSpell类lumus方法中使用Wand类.wandtype属性.但我不断收到错误"AttributeError:'CastSpell'对象没有属性'wandtype'."
此代码有效:
class Wand(object):
def __init__(self, wandtype, length):
self.length = length
self.wandtype = wandtype
def fulldesc(self):
print "This is a %s wand and it is a %s long" % (self.wandtype, self.length)
class CastSpell(object):
def __init__(self, spell, thing):
self.spell = spell
self.thing = thing
def lumus(self):
print "You cast the spell %s with your wand at %s" %(self.spell, self.thing)
def wingardium_leviosa(self):
print "You cast the levitation spell."
my_wand = Wand('Phoenix-feather', '12 inches')
cast_spell = CastSpell('lumus', 'door') …通过艰难的方式学习Python,第25课.
我尝试执行脚本,结果如下:
myComp:lphw becca$ python l25
myComp:lphw becca$
终端中没有打印或显示任何内容.
这是代码.
def breaks_words(stuff):
"""This function will break up words for us."""
words = stuff.split(' ')
return words
def sort_words(words):
"""Sorts the words."""
return sorted(words)
def print_first_word(words):
"""Prints the first word after popping it off."""
word = words.pop(0)
print word
def print_last_word(words):
"""Prints the last word after popping it off."""
word = words.pop(-1)
print word

"""Takes in a full sentence and returns the sorted words."""
words = break_words(sentence)

我已经尝试通过向a :hover以下内容添加状态来编辑CSS :
.fancybox-title-over-wrap {
}
我甚至试过在这里玩CSS可见性设置:
.fancybox-opened .fancybox-title {
}
但是,我没有运气.
我必须在实际的JS文件中更改一些内容吗？任何帮助将非常感谢!
