Question

我正在处理我的python脚本，因为我创建了一个列表来存储数组中的元素。

我的if语句有问题。如果我有值375，我试图找到这些元素，但它不会让我传递if语句。

以下是代码：

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

以下是我用于从数组中打印的元素列表：

当我试图找到375的元素时，能否帮助我如何传递if语句？

Answer 1

由于program_x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

if pos_X == '375'

Answer 2

如果以这种方式将字符串存储在列表中，

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

然后使用in关键字检查单词

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

如果元素返回true，如何检查if语句
