Re: Windows switch between python 2 and 3

py.exe; for Python 2.7, use `py -2.7`; for Python 3.5, use `py -3.5`. There are also shortcuts for "latest Python 2" and "latest Python 3", `py -2` and `py -3` respectively. Calling `py` on its own will default to matching `py -2`, but settings can be changed in C:\Windows\py.ini.

Windows switch between python 2 and 3

Hi, I installed Python 2.7 and Python 3.5 64 bit versions on Win 10. Under C:\Python35 C:\Python27 Both have been set in environment variable Path. When I type python in cmd, it only gives me python 2.7, I am wondering how to switch between 2 and 3 in command prompt. cheers --

Re: repr/str diff between Python 2 and 3

Thanks everyone. I'm not going to try to be too cute, and will just change my test case. I'm leaving Python 2 behind in this particular case for now anyway. I can always return to the issue if I decide I need Python 2.7 support at some point in the future. Skip --

I'm trying to port some code from Python 2 to 3, and beyond the usual mechanical stuff, I've encountered a difference between the str() of floats. Here's an example. In Python 3 I get: >>> print(repr(27.04 - 0.01)) 27.028 >>> print(str(27.04 - 0.01)) 27.0299
