64bit prcessor with 32bit operating system program compatibilities?

on 64bit processors. with 32bit operating system all programs works fine ?

like suppose all python 32bit installation programs works fine ? or there are any issues found?

a program or software developed on 32bit operating system & 32bit processor installed on 32bit operating system and 64bit processor does it work well or any issues?

why i am asking this, bec these days on market all 64bit processor os computers coming and mostly sold. there is no choice also for us..if i want to buy a i5proces开发者_StackOverflowsor computer..

If you have say a 64bit edition of Windows, there is the 64bit version of Python available.

The advantage for you is that you can have more RAM (> 4GB) and thus access large amounts of data.

The difference between 32bit and 64bit in case of Python should not worry you at all. Python is a high level language, the process architecture and the difference in size of data types is not your concern.

Should be fine. X64 processors run x32 code natively. My dev PC is x64 but it has run a 32 bit OS and code with no problems whatsoever for 4 or so years.

Similarly, it should run 16 bit (8086) code and operating systems just fine!
