python中文乱码的解决方法:1、文件存储设为utf-8格式,并使用encoding将编码声明为utf-8;2、在中文前面加上个小u标记,将中文用unicode存储;3、把中文强制转换为GBK或者unicode编码。
python中文乱码问题的解决方法:
1、demo.py 文件和编码声明都为 GBK
这种方法比较笨,就是把 demo.py 文件改为 GBK 存储,而且编码声明也是GBK,个人不推荐。
# encoding:gbk s = "中文" print s print repr(s)
2、中文用 unicode 表示
只要在中文前面加上个小u标记,后面的中文就用 unicode 存储了。
# encoding:utf-8 s = u"中文" print s print repr(s)
cmd 下是可以打印 unicode 字符的,如下:
3、把中文强制转换为GBK或者unicode编码
强制转换为unicode编码,在 Python 中编码是可以互相转换的,比如从utf-8转换为gbk,不同编码之间不能直接转换,需要通过unicode字符集中间过渡下,从上面基础知识可知unicode是一种字符集,不属于编码,而utf-8是具体实现unicode思想的一种编码。utf-8转换为unicode是一种解码过程,通过decode可从utf-8解码成unicode。
# encoding:utf-8 s = "中文" u = s.decode('utf-8') print u print type(u) print repr(u)
强制转换为gbk编码,上一步已经从utf-8转换为unicode了,从unicode是编码的过程,通过encode实现。
# encoding:utf-8 s = "中文" u = s.decode('utf-8') g = u.encode('gbk') print g print type(g) print repr(g)
总结
windows cmd 窗口下不支持utf-8,想要显示中文必须转换为gbk或者unicode,而 Python idle 中这三种编码都支持。中文乱码的出现都是由于编码不一致导致的,存储的是用utf-8,打印的时候用gbk就会乱码了,所有要保证不乱码尽量保持统一,建议全部使用unicode。

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
