查找阵列中的元素列表

我正在处理我的python脚本以获取数组中的元素列表。我使用变量position_x = elem.getX()来获取像素大小的元素列表。查找阵列中的元素列表

所以，当我试试这个：

for elem in self.program_buttons: 
    position_x = elem.getX() #Get positionX 
    #print the list of elements with 375 
    print position_x

我会得到的结果是这样的：

这似乎是你在说什么。

elems = [elem for elem in self.program_buttons if elem.getX() == 375] 
for elem in elems: 
    # the same code you have before -- the above line filters it

大概其可读性：

for elem in self.program_buttons: 
    position_x = elem.getX() 
    if position_x == 375: 
     # use the same code you have to print it -- this is your filter 
    else: 
     continue 
    # these last two lines do literally nothing and can be excluded 
    # I just find them more readable!!

基本上你根据该通知数量是否375筛选结果。我的第一个代码给你一个列表elems，其中包含通知其通过过滤器的每个元素。代码的第二位不会产生这样的列表，只需打印通过的代码行即可。

如果你从字面上只希望375 S的输出，你可以尝试：

elems = [elem for elem in self.program_buttons if elem.getX() == 375] 
for elem in elems: 
    print(375)

或

for elem in self.program_buttons: 
    position_x = elem.getX() 
    if position_x == 375: 
     print(375)

非常感谢您的帮助。我有一个错误：'AttributeError：'int'object has no attribute'endswith''，如果position_x.endswith（“375”）：'，错误在这行上跳跃。你知道我为什么得到一个错误吗？ – Rob 2014-12-18 23:24:21

@Rob看起来像'position_x'不是一个字符串，它是一个int。你似乎非常确信这是一个字符串，所以我不知道如何帮助你。 – 2014-12-18 23:27:25

哦，对不起，这是我的错误。我认为这是一个字符串。我没有意识到这是一个整数。你知道如何用'375'获得整数吗？ – Rob 2014-12-18 23:32:07
