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()

以上这篇将python安装信息加入注册表的示例就是小编分享给大家的全部内容了，希望能给大家一个参考，也希望大家多多支持脚本之家。
