I m playing Cloudrip Mountain. I just finished Zoo keeper lv with the help of pre-existent code which introduce a new things without explanation. They are “i” and range() function.
for i in range(4): hero.summon("soldier") for j in range(len(friends))
I am so confused that what are"i" and “j” in the code and what is range() function for? Why there are no explanation in the hints. It leads to another problem that I m stuck in the next level Noble Sacrifice which requires me to “Use range to make an array to loop over” I will be grateful for anyone can help.
