HomeBackend DevelopmentPython Tutorial编写Python脚本使得web页面上的代码高亮显示

做了一个在线代码高亮的项目,强大的Python一如既往没让我失望,一个强大的Pygments模块可以对多种(很多)语言进行代码高亮

下面来介绍一下它:

首先安装很简单,使用easy_install来进行安装:

easy_install pygments

安装完后我们来使用,Python的简单不会让大家失望:

from pygments.lexers import PythonLexver
from pygments.formatters import HtmlFormatter
from pygments import highlight

formatter = HtmlFormatter(encoding='utf-8', style = 'emacs', linenos = True)
code = highlight('print "hello, world"', PythonLexer(), formatter)

print code

结果

'<table class="highlighttable"><tr><td class="linenos"><div class="linenodiv"><pre class="brush:php;toolbar:false">1
<span class="k">print</span> <span class="s">"hello, world"</span>\n
\n'

这样就简单的对代码进行了高亮,当然如果你做了上面操作,然后把内容输入到一个文件里查看,肯定大呼坑爹,因为根本没高亮,因为默认是不会输出css的 我们还要获取css加入到html中去:

css = formatter.get_style_defs()

然后把css内容和上面的html一起写入到html文件就可以看到高亮的代码了(千万不要告诉我你不知道css应该放在什么位置)

How do you slice a Python array?How do you slice a Python array?May 01, 2025 am 12:18 AM

The basic syntax for Python list slicing is list[start:stop:step]. 1.start is the first element index included, 2.stop is the first element index excluded, and 3.step determines the step size between elements. Slices are not only used to extract data, but also to modify and invert lists.

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
