将python安装信息加入注册表的示例

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
