Python 如果元素返回true，如何检查if语句

我正在编写python脚本，因为我创建了一个列表来存储数组中的元素

我对if语句有问题。如果我有值

375

，我将尝试查找元素，但它不允许我传递if语句

代码如下：

program_X = list()

#create the rows to count for 69 program buttons
for elem in programs_button:
    program_width.append(elem.getWidth())
    program_X.append(elem.getX())
program_X = map(str, program_X)


#get the list of position_X for all buttons
for pos_X in programs_X:

    #find the position with 375
    if pos_X == 375:
        print pos_X

以下是用于从数组打印的元素列表：

当我试图查找

375

的元素时，您能帮助我如何传递if语句吗？

因为

程序包含字符串元素：

program_X = map(str, program_X)
                 ^

您需要更改以下内容：

if pos_X == 375

到

如果以这种方式在列表中存储字符串

program_X = ['14:08:55 T:1260  NOTICE: 8081.35', ...]

然后在

关键字中使用

，检查单词

for pos_X in programs_X:    
    #find the position with 375
    if '375' in pos_X:
        print pos_X

请定义如何在列表中存储元素。非常感谢您的帮助。我有一个小问题，列表中有7个元素，但它会让我打印元素14次。我怎么能只打印7次而不是14次呢？@Rob不客气，你是说
program_x
包含7个元素吗？当然可以，program_x将包含14个元素，它应该包含7个
375
元素。你想让我发布完整的代码吗？这是在将375更改为“375”后发生的吗？您能显示“program_x”的元素吗？很好，很抱歉，我忘记删除
program_x.append（elem.getX（））
，因为我已经在使用
program_x.append（position_start）
使其成倍增长。现在问题解决了。非常感谢您的帮助，祝您圣诞快乐
for pos_X in programs_X:    
    #find the position with 375
    if '375' in pos_X:
        print pos_X
