Question

我有这个字符串基本上是一些html

<acronym class="non-experimental-qualifier" title="Indicates that the information given is not based on experimental findings." onclick="dialog('non_experimental_qualifiers'); Event.stop(event || window.event); return false" onmousedown="Event.stop(event || window.event);">By similarity</acronym>. <a class="attribution" href="http://hamap.expasy.org/unirule/

无论如何我可以在python中将其读作字符串。。。通常它只有一种类型的'或'所以我可以用另一种来串起它但......它有两种

我怎么能把它变成一个字符串？像：

html = '<acronym class="non-experimental-qualifier" title="Indicates that the information given is not based on experimental findings." onclick="dialog('non_experimental_qualifiers'); Event.stop(event || window.event); return false" onmousedown="Event.stop(event || window.event);">By similarity</acronym>. <a class="attribution" href="http://hamap.expasy.org/unirule/'

Answer 1

您可以使用triple-quoted string：

html = '''<acronym class="non-experimental-qualifier" title="Indicates that the information given is not based on experimental findings." onclick="dialog('non_experimental_qualifiers'); Event.stop(event || window.event); return false" onmousedown="Event.stop(event || window.event);">By similarity</acronym>. <a class="attribution" href="http://hamap.expasy.org/unirule/'''

以下是演示：

>>> mystr = '''It's a "string"'''
>>> mystr
'It\'s a "string"'
>>>

Answer 2

您可以使用\'和\"转义引号，也可以使用三引号：

example1 = 'She\'s fond of saying "Hello"'
example2 = "She's fond of saying \"Hello\""
example3 = '''She's fond of saying "Hello"'''
example4 = """She's fond of saying "Hello\""""

请注意三重引号字符串末尾的结束";它必须被逃脱，不计入最后3个收盘价。

演示：

>>> example1 = 'She\'s fond of saying "Hello"'
>>> example2 = "She's fond of saying \"Hello\""
>>> example3 = '''She's fond of saying "Hello"'''
>>> example4 = """She's fond of saying "Hello\""""
>>> example1 == example2 == example3 == example4
True

此外，新行允许并保存在三引号字符串中，从而形成一个非常易读的文字HTML值：

html = '''\
<acronym class="non-experimental-qualifier" 
         title="Indicates that the information given is not based on experimental findings." 
         onclick="dialog('non_experimental_qualifiers'); Event.stop(event || window.event); return false" 
         onmousedown="Event.stop(event || window.event);">By similarity</acronym>. 
    <a class="attribution" href="http://hamap.expasy.org/unirule/'
'''

Answer 3

我很困惑 - 从外部对象读取字符串，您不需要做任何事情。 Python包含电池并将处理引号。我拿了你的字符串并将其保存在一个文件中，然后使用open（）。read（）

读取它

>>>mystring = open('c:\\mytest.txt').read()

>>>mystring
'<acronym class="non-experimental-qualifier" title="Indicates that the information given is not based on experimental findings." onclick="dialog(\'non_experimental_qualifiers\'); Event.stop(event || window.event); return false" onmousedown="Event.stop(event || window.event);">By similarity</acronym>. <a class="attribution" href="http://hamap.expasy.org/unirule/'

所以我的问题是，你的意思是读或你是否正在尝试构建一个像上面那样的字符串？

如果它有“和'？Python，我该怎么读这个字符串
