10-fold cross-validation, over 60 projects

I am trying to write python code to train and test 60 projects with 10 folds. I want to split the list in 10ths where each fold has 1/10th of projects. For example since I have 60 projects I want to divide them on the 10 folds so each fold has 6 projects. Then test in the first fold and train on others and so on like:

Train on fold 2+3+4+5+6+7+8+9+10, test on fold 1

Train on fold 1+3+4+5+6+7+8+9+10, test on fold 2
. . .
Train on fold 1+2+3+4+5+6+7+8+9, test on fold 10

Note, all 60 projects are in my desktop.

so how can I manage each fold ? can some one help me ??
