本文实例讲述了python实现中文转换url编码的方法。分享给大家供大家参考,具体如下:
今天要处理百度贴吧的东西。想要做一个关键词的list,每次需要时,直接添加 到list里面就可以了。但是添加到list里面是中文的情况(比如‘丽江'),url的地址编码却是'%E4%B8%BD%E6%B1%9F',因此需 要做一个转换。这里我们就用到了模块urllib。
>>> import urllib >>> data = '丽江' >>> print data 丽江 >>> data '\xe4\xb8\xbd\xe6\xb1\x9f' >>> urllib.quote(data) '%E4%B8%BD%E6%B1%9F'
那我们想转回去呢?
>>> urllib.unquote('%E4%B8%BD%E6%B1%9F') '\xe4\xb8\xbd\xe6\xb1\x9f' >>> print urllib.unquote('%E4%B8%BD%E6%B1%9F') 丽江
细心的同学会发现贴吧url中出现的是%C0%F6%BD%AD,而非'%E4%B8%BD%E6%B1%9F',其实是编码问题。百度的是gbk,其他的一般网站比如google就是utf8的。所以可以用下列语句实现。
>>> import sys,urllib >>> s = '丽江' >>> urllib.quote(s.decode(sys.stdin.encoding).encode('gbk')) '%C0%F6%BD%AD' >>> urllib.quote(s.decode(sys.stdin.encoding).encode('utf8')) '%E4%B8%BD%E6%B1%9F' >>>
希望本文所述对大家Python程序设计有所帮助。

In Python 3, two lists can be connected through a variety of methods: 1) Use operator, which is suitable for small lists, but is inefficient for large lists; 2) Use extend method, which is suitable for large lists, with high memory efficiency, but will modify the original list; 3) Use * operator, which is suitable for merging multiple lists, without modifying the original list; 4) Use itertools.chain, which is suitable for large data sets, with high memory efficiency.

Using the join() method is the most efficient way to connect strings from lists in Python. 1) Use the join() method to be efficient and easy to read. 2) The cycle uses operators inefficiently for large lists. 3) The combination of list comprehension and join() is suitable for scenarios that require conversion. 4) The reduce() method is suitable for other types of reductions, but is inefficient for string concatenation. The complete sentence ends.

Key features of Python include: 1. The syntax is concise and easy to understand, suitable for beginners; 2. Dynamic type system, improving development speed; 3. Rich standard library, supporting multiple tasks; 4. Strong community and ecosystem, providing extensive support; 5. Interpretation, suitable for scripting and rapid prototyping; 6. Multi-paradigm support, suitable for various programming styles.

Python is an interpreted language, but it also includes the compilation process. 1) Python code is first compiled into bytecode. 2) Bytecode is interpreted and executed by Python virtual machine. 3) This hybrid mechanism makes Python both flexible and efficient, but not as fast as a fully compiled language.

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),
