pywin32的安装

1. 下载地址：
   https://sourceforge.net/projects/pywin32/
   根据你的电脑是32位的还是64位的，还有根据你的python版本是多少来决定。
   在这里，我的选择的是pywin32-221.win-amd64-py3.6

2. 安装遇到的问题，python version 3.6 required,which was not found in the registr
   是因为安装的python权限是对所有人，则没有添加到注册表中，故执行下列代码，可以解决。

from __future__ import print_functionimport systry:    from winreg import *except ImportError:    from _winreg import *# tweak as necessaryversion = sys.version[:3]installpath = sys.prefixregpath = "SOFTWARE\\Python\\Pythoncore\\{0}\\".format(version)installkey = "InstallPath"pythonkey = "PythonPath"pythonpath = "{0};{1}\\Lib\\;{2}\\DLLs\\".format(    installpath, installpath, installpath)def RegisterPy():    try:        reg = OpenKey(HKEY_CURRENT_USER, regpath)    except EnvironmentError as e:        try:            reg = CreateKey(HKEY_CURRENT_USER, regpath)            SetValue(reg, installkey, REG_SZ, installpath)            SetValue(reg, pythonkey, REG_SZ, pythonpath)            CloseKey(reg)        except:            print("*** Unable to register!")            return        print("--- Python", version, "is now registered!")        return    if (QueryValue(reg, installkey) == installpath and        QueryValue(reg, pythonkey) == pythonpath):        CloseKey(reg)        print("=== Python", version, "is already registered!")        return    CloseKey(reg)    print("*** Unable to register!")    print("*** You probably have another Python installation!")if __name__ == "__main__":    RegisterPy()

3，问题2：ImportError: DLL load failed: %1 不是有效的 Win32 应用程序。
表示python版本的位数与安装模块包的位数不相同导致的。
4，安装成功
