背景

重裝系統，發現之前裝在E盤的python可以直接使用，就只是將python的安裝目錄加入到環境變量中，也一直沒有管它，今天跟天軟交互的時候發現一直不成功，猜測可能是沒有注冊表信息。

從網上找的一段代碼，直接復制運行即可，留存備查。

代碼

py3.5.2

import sysfrom winreg import *# tweak as necessaryversion = sys.version[:3]installpath = sys.prefixregpath = "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()

以上這篇將python安裝信息加入注冊表的示例就是小編分享給大家的全部內容了，希望能給大家一個參考，也希望大家多多支持武林網之家。
