Make "python" Run Python3 At The Prompt

I have two python installations.. python --> /Users/fraz/anaconda/bin/python (python2.7) python3.7 --> /usr/local/bin/python3.7 Now.. I want reassign the commands. Such that

Solution 1:

follow this question, modify your ~/.bashrc, add a new line:

alias python=python3.7

save and exit then open terminal, type

source ~/.bashrc

in my machine, typing python2 will open python 2.x by default. but if needed, you can add a new alias

alias python2=python2.7

Solution 2:

you can use softlink

ln -s /usr/bin/python /usr/local/bin/python3.7
