我有两个加号和减号的图像.我想将这些图像变成另一个图像的缩放和缩小按钮.

<div id="container">
    <div id="upperMall" >
        <img alt="" height="972" src="images/UpperMall.png" width="1728">
    </div>
</div>

<div id="zoom">
    <img alt="" height="75" src="images/btnMinus.png" width="75">
    <img alt="" height="75" src="images/btnplus.png" width="75">
</div>

我有一个项目清单.然后我有一个功能,在那里找到一个项目.

def find(self, runners):
    for runners in self._runners:
        if runners.name == name:
            return runners

因此,当我键入runnersworld.find(peter)它应该带回一个打印语句,如"找到记录或记录未找到.每个记录都有一个runid和一个跑步者名称.但是当我运行这个函数时,我得到一个全局变量名称,它没有定义.两个罚款我有:

RunnerClass

class Runner(object):
def __init__ (self, runnerid, name):
    self._runnerid = runnerid
    self._name = name

@property
def runnerid(self):
    return self._runnerid

@property
def name(self):
    return self._name

@name.setter
def name(self, name):
    self._name = name

def get_fee(self, basicfee, moneyraised):
    raise NotImplementedError("AbstractMethod")        

def __str__(self): 
    rep = "Runner: " + self._runnerid + " " + self._name + "\n"
    return rep

俱乐部课程

class Club (object):
def __init__(self, clubid, name):
    self._clubid …

我有一个问题,但我真的不明白他们要求我做什么.他们给我的问题是:

这个练习的目标是创建两个列表称为x_list和y_list区,其中包含变量的10个实例x,并y分别.您还需要创建一个名为列表big_list,其中包含变量x和y,每组10次,通过连接你已经创建了两个列表.

代码是:

x = object()
y = object()

# change this code
x_list = [x]
y_list = [y]
big_list = x_list + y_list

print "x_list contains %d objects" % len(x_list)
print "y_list contains %d objects" % len(y_list)
print "big_list contains %d objects" % len(big_list)

# testing code
if x_list.count(x) == 10 and y_list.count(y) == 10:
    print "Almost there..."
if big_list.count(x) == 10 and big_list.count(y) == …
