compile()函数允许程序员在运行时刻迅速生成代码对象,然后就可以用exec 语句或者内建函数eval()来执行这些对象或者对它们进行求值。一个很重要的观点是:exec 和eval()都可以执行字符串格式的Python代码。当执行字符串形式的代码时,每次都必须对这些代码进行字节编译处理。compile()函数提供了一次性字节代码预编译,以后每...
需要说明的是在 Python2 中exec不是函数,而是一个内置语句; 3、如果编译的源码不合法,此函数会触发 SyntaxError 异常;如果源码包含 空字节(空字符串),则3.5版本以前会触发 ValueError 异常,3.5版本后则不会触发可以编译通过并执行。注意: 1) 在‘single’ 或‘eval’ 模式编译多行代码字符串(这些串必须是一个完...
1、去python目录下script,其中有pyinstaller.exe,在此目录中打开cmd 4、输入pyinstaller打包的指令就好啦
1、打开cmd,切换到 cd c:\\python34 2、运行 1)python3-m py_compile D:\test.py#跟随完整路径 2)python3-m py_compile/root/src/{file1,file2}.py#这是同时转换多个文件 3、会在需转译文件的目录下生成一个“__pycache__”目录/test.cpython-39.pyc文件 #-m 相当于脚本中的import,这里的-m py...

The Python version that comes with Ubuntu20.04 is 3.8. If you want to install python3.9, you can use this command:sudo apt install python3.9 The repository of Ubuntu20.04 does not include python3.10, so let's compile and install it from the source code!
