# Simple script which automatically defines certain aliases for python,

|

|

|
# Assume we have these installed pyenv python versions 3.6.5, 3.6.12 and 3.10.1:
|
|
# - Set full-version aliases: py3.6.5, py3.6.12 and py3.10.1
|
|
# - Set py3 to 3.10.1 (latest with major version 3)
|
|
# - Set py3.6 to 3.6.12 (latest with major version 3 and minor version 6)
|
|
# - Set py3.10 to 3.10.1 (latest, and only python with major version 3 and minor version 10)
|
|
|
|
|
|
