you should almost certainly put theeval "$(pyenv init - bash)"line into.bash_profile, andnotinto.bashrc. Otherwise, you may observe strange behaviour, such aspyenvgetting into an infinite loop. See#264for details.

for i in myList: print (i) 1. 2. As we can see we are using a variablei, which represents every single element stored in the list, one by one. Our loop will run as many times, as there are elements in the lists. For example, inmyListthere are 6 elements, thus the above loop...
