git - What are the pitfalls of "always" rebasing? -

-
a few people @ work swear git pull --rebase . in fact, won't git pull without it, when several people working on shared branch. it understanding rewrites history . in fact, have seen said 1 should never rebase on public/shared branch . my question: what concrete example of way rebasing "rewrites history"? what concrete examples of bad things occur if violate "golden rule of rebasing"? possible difference suggested dupe: i'm not talking rebasing master feature branch. talking several developers working on same feature branch, doing git pull --rebase , making changes, pushing (doing pull --rebase if push rejected), etc. we use in our workflows. if use on short-lived branches it's relatively safe. you're replaying your local commits (rewriting that history) on top of pushed commits of coworkers. if you're rebasing entire collaboration branch in best interests coordinate coworkers. otherwise it's easy lose work

Python- Calling elements from a list returns wrong ones -

from list, shuffle: rotationspeedarray = [4,6,8,10] #in hz random.shuffle(rotationspeedarray) i try call 1 specific number @ time, print rotationspeedarray[0] print rotationspeedarray[1] print rotationspeedarray[2] print rotationspeedarray[3] but whenever this: #an actual empty space [ 6 , the code part meant draw figure , rotate it. want different speeds, that's why created list takes 1 of rotation speeds , uses it. figure moves each trial @ different speed, process of taking 1 value @ time works. don't why whenever ask show me each value of list, this. i hope sufficiently clear; please don't hesitate asking me question. i'm having no problems. sure you're not surrounding converting list string somewhere down line?? it's treating rotationspeedarray string, why ask. random.shuffle throw typeerror if had put quotes around list, i'm assuming there code you're not showing somewhere past converting string? import random rota
