將python安裝信息加入注冊表的示例

今天小編就為大家分享一篇將python安裝信息加入注冊表的示例，具有很好的參考價值，希望對大家有所幫助。一起跟隨小編過來看看吧

背景

重裝系統(tǒng)，發(fā)現(xiàn)之前裝在E盤的python可以直接使用，就只是將python的安裝目錄加入到環(huán)境變量中，也一直沒有管它，今天跟天軟交互的時候發(fā)現(xiàn)一直不成功，猜測可能是沒有注冊表信息。

從網(wǎng)上找的一段代碼，直接復制運行即可，留存?zhèn)洳椤?/p>

代碼

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()
