我尝试了这个但没用
print (log.split("ecsdcsdcsdfvdfv",1)[1])
答案 0 :(得分：3)
您可以尝试
log.split('":"')[1].split('","')[0]
但这不是完成您要实现的目标的最佳方法。更好地解析它并得到您想要的。

这将产生预期的结果。
您使用 code:
html:
<div class="panel panel-info">
<div class="panel-heading collapsed" data-toggle="collapse" data-target="#bar">
<i class="fa fa-fw fa-chevron-up"></i>
<i class="fa fa-fw fa-chevron-down"></i>Keywords
</div>
<div class="panel-body">
<div class="collapse" id="bar">
<ul>
<li><button onclick="myFunction()">+ Add Keyword</button></li>
<li>
<div id="myDIV">
<form>Keyword<br/><br>
<input type="text" value="" id="keywordname" name="name">
</input>
</form>
<button onclick="saveFunction2()">Save </button>
</div>
</li>
</ul>
</div>
</div>
</div>
<div class="panel panel-info">
<div class="panel-heading collapsed" data-toggle="collapse" data-target="#bar">
<i class="fa fa-fw fa-chevron-up"></i>
<i class="fa fa-fw fa-chevron-down"></i>others
</div>
<div class="panel-body">
<!-- The inside div eliminates the 'jumping' animation. -->
<div class="collapse" id="bar">
<button onclick="myFunction()">+ Add Keyword</button>
</div>
</div>
</div>
CSS:
.panel-heading.collapsed .fa-chevron-up,
.panel-heading .fa-chevron-down {
display: none;
}
.panel-heading.collapsed .fa-chevron-down,
.panel-heading .fa-chevron-up {
display: inline-block;
}
i.fa {
cursor: pointer;
margin-right: 5px;
}
.collapsed ~ .panel-body {
padding: 0;
}
ul, li { list-style: none; margin: 0; padding: 0; }
ul { padding-left: 1em; }
li { padding-left: 1em;
border: 1px dotted black;
border-width: 0 0 1px 1px;
}
li.container { border-bottom: 0px; }
li.empty { font-style: italic;
color: silver;
border-color: silver;
}
li p { margin: 0;
background: white;
position: relative;
top: 0.5em;
}
li ul {
border-top: 1px dotted black;
margin-left: -1em;
padding-left: 2em;
}
ul li:last-child ul {
border-left: 1px solid white;
margin-left: -17px;
}
#myDIV {
width: 100%;
padding: 50px 0;
text-align: left;
background-color: white;
margin-top: 20px;
}
的方式是错误的，您没有包含.split()字符。

如果要获取":"和","之间的字符串，则可以使用正则表达式来实现。
re.match('(.*\":\")([^\",\"]*)(\",\".*)', log).group(2)
