| tabnanny | Tool for detecting white space related problems in Python source files in a directory tree. | |
| pyclbr | Supports information extraction for a Python class browser. | |
| py_compile | Compile Python source files to byte-code files. | |
| compileall | Tools for byte-compiling all Python source files in a directory tree. | |
| dis | Disassembler for Python byte code. | |
| pickletools | Contains extensive comments about the pickle protocols and pickle-machine opcodes, as well as some useful functions. | |
| distutils | Support for building and installing Python modules into an existing Python installation. |
