Das deutsche Python-Forum

Python 27 and 36 are abreast installed. I can enable 36
Python 2.7.5 (default, May 31 2018, 09:41:32)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-28)] on linux2
>>scl enable rh-python36 bash<<
Python 3.6.3 (default, Jan 9 2018, 10:19:07)
[GCC 4.8.5 20150623 (Red Hat 4.8.5-11)] on linux
,but after a reboot Python 27 is the current version.

how can you solve the problem?
Any ideas

Thank all of you

You don’t. There is probably plenty of things relying on „python“ being 2.7.

Just use python3 or even python3.6 of you need it.
