将python安装信息加入注册表的示例

人气:0

背景

重装系统,发现之前装在E盘的python可以直接使用,就只是将python的安装目录加入到环境变量中,也一直没有管它,今天跟天软交互的时候发现一直不成功,猜测可能是没有注册表信息。

从网上找的一段代码,直接复制运行即可,留存备查。

代码

py3.5.2

import sys

from winreg import *

# tweak as necessary
version = sys.version[:3]
installpath = sys.prefix

regpath = "SOFTWARE\\Python\\Pythoncore\\%s\\" % (version)
installkey = "InstallPath"
pythonkey = "PythonPath"
pythonpath = "%s;%s\\Lib\\;%s\\DLLs\\" % (
  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()

py2.*版本
