Python字典会抛出无效的语法

标签： python dictionary syntax

为什么此代码会抛出无效的语法错误？我很确定大约三个月前它运行良好。关于字典，Python语言有什么变化吗？错误如下：

File "code.py", line 4
'den'{'adm':2.4,'den':0,'ear':3.5,'edi':3.6,'eug':1.6,'fra':3.0,'thu':3.1,\
SyntaxError: invalid syntax

如果我注释掉第4行和第5行，则错误指向第7行。错误始终引用第二个单引号字符。在第四行中，它指向＆＃34; '＆＃34;中的N之后的den。

以下是代码：

milevalue = {'adm':{'adm':0,'den':2.4,'ear':3,'edi':3.2,'eug':2.6,'fra':2.1,'thu':1.2,\

答案 0 :(得分：3)

在... 'cen':.9} ,\ \ den:{... 之后的近距离大括号之后，您似乎错过了一个逗号。试试这个修复：

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8"/>
    <script type="text/javascript">
        window.onload = function () {
            var img = document.getElementById('embedImage');
            var button = document.getElementById('saveImage');
            img.src = 'data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUA'+
            'AAAFCAYAAACNbyblAAAAHElEQVQI12P4//8/w38GIAXDIBKE0DHxgljNBAAO'+
            '9TXL0Y4OHwAAAABJRU5ErkJggg==';
            img.onload = function () {
                button.removeAttribute('disabled');
            };
            button.onclick = function () {
                window.location.href = img.src.replace('image/png', 'image/octet-stream');
            };
        };
    </script>
</head>
<body>
    <img id="embedImage" alt="Red dot"/>
    <input id="saveImage" type="button" value="save image" disabled="disabled"/>
</body>
</html>

我很确定这个文件在这种情况下三个月前无法正常运行。

您在字符串'den'之前丢失了'cen':.9。

答案 2 :(得分：2)

通过明智地使用空格，可以更容易地发现这种语法错误。至少，错误信息可以让您更好地了解在哪里寻找。

milevalue = {
  'adm': {
    'adm': 0,

答案 5 :(得分：0)

在我的例子中，一个大字典的值之一包含一个未转义的单引号，如 'today's'。通过转义 'today\'s' 来修复它（双引号也有效）。以防万一它对某人有帮助，这些小问题很容易在大字典中遗漏，特别是如果使用其他代码自动生成。
