源代码如下：

> 参数 `-O` ：混淆所有函数/方法名、变量和类。默认是不要混淆。

我这里使用参数 `-O` 进行源码混淆。

如果运行时报错：`UnicodeDecodeError: 'gbk' codec can't decode byte 0x80 in position 54: illegal multibyte sequence`  
**可以查看解决方法：**  
[**Python** 技术篇 - 修改 **pyminifier** 库源码解决编码不一致导致的报错问题][Python_ _ - _ _pyminifier_]

转换后生成新文件，**minified** 文件夹里也是转化后的内容，这个是默认生成的，通过参数 `-d` 可以进行指定。

可以看到方法和变量名都被改了，而且注释也被默认去掉了，这样就一定程度上提高了我们源代码的安全性。  
当然默认会被编码为 **gbk** ，如需调整可以自行转化一下文件编码。

**pyminifier** 详细命令方法如下：

pyminifier -h
    Usage: pyminifier [options] "<input file>"
    
    Options:
      --version             show program's version number and exit -h, --help show this help message and exit -o <file path>, --outfile=<file path> Save output to the given file. -d <file path>, --destdir=<file path> Save output to the given directory. This option is required when handling multiple files. Defaults to './minified' and will be created if not present. 将输出保存到给定的目录。当处理多个文件时，此选项是必需的。默认为'./minified'，如果不存在，将被创建。 --nominify Don't bother minifying (only used with --pyz).
    
      --use-tabs            Use tabs for indentation instead of spaces.
      						使用制表符代替空格来缩进。
      
      --bzip2               bzip2-compress the result into a self-executing python
                            script.  Only works on stand-alone scripts without
                            implicit imports.
                            以bzip2方式压缩将结果到一个自动执行的python脚本中。只能在独立脚本上工作，不需要隐式导入。
                            
      --gzip                gzip-compress the result into a self-executing python
                            script.  Only works on stand-alone scripts without
                            implicit imports.
                            以gzip方式压缩结果到一个自执行的python脚本中。只能在独立脚本上工作，不需要隐式导入。
                            
      --lzma                lzma-compress the result into a self-executing python
                            script.  Only works on stand-alone scripts without
                            implicit imports.
    						以lzma方式压缩将结果到一个自动执行的python脚本中。只能在独立脚本上工作，不需要隐式导入。
    
      --pyz=<name of archive>.pyz
                            zip-compress the result into a self-executing python
                            script. This will create a new file that includes any
                            necessary implicit (local to the script) modules.
                            Will include/process all files given as arguments to
                            pyminifier.py on the command line.
      -O, --obfuscate       Obfuscate all function/method names, variables, and
                            classes.  Default is to NOT obfuscate.
      --obfuscate-classes   Obfuscate class names.
      --obfuscate-functions
                            Obfuscate function and method names.
      --obfuscate-variables
                            Obfuscate variable names.
      --obfuscate-import-methods
                            Obfuscate globally-imported mouled methods (e.g.
                            'Ag=re.compile').
      --obfuscate-builtins  Obfuscate built-ins (i.e. True, False, object,
                            Exception, etc).
      --replacement-length=1
                            The length of the random names that will be used when
                            obfuscating identifiers.
      --nonlatin            Use non-latin (unicode) characters in obfuscation
                            (Python 3 only).  WARNING: This results in some
                            SERIOUSLY hard-to-read code.
      --prepend=<file path>
                            Prepend the text in this file to the top of our
                            output.  e.g. A copyright notice.
