Python Print Displays -


i having problem project i'm working. problem having @ end of display list getting negative number, wondering if give me direction on how fix problem? need zero.

initalprice = float(input("enter price of computer: ")) month = 0 downpayment = initalprice * .10 balance = (initalprice - downpayment) aninterest = balance * .01 / 12 monthlypayment = balance * 0.05   print("%0s%20s%20s%20s%13s%23s" %("month", "current balance", "interest  owed", "principal owed", "payment", "balance remaining"))   in range(1, 100):      #aninterest = aninterest     if balance >= 0:         initalprice = initalprice - initalprice * .10           principal = monthlypayment - aninterest         balance = balance + aninterest - monthlypayment         print("%0d%20.2f%20.3f%20.2f%13.2f%23.2f" %(i, initalprice, aninterest, principal, monthlypayment, balance))

you subtracting constant amount monthlypayment (ie. 10% of balance). if balance plus interest less monthlypayment balance becomes negative. have simple check see not case.

p.s. recommend using while loop problem loop can either iterate many times, or not enough times.

node.js - How do I prevent MongoDB replica set from querying the primary? -

read-operations-only: is there way have mongodb replica set, make mongodb instance on box connected to, mongodb gets queried? i have 3 ec2 instances behind aws load balancer. on each ec2 instance runs mongodb, part of replica set. i have express endpoints on nodejs , connect replica set follows mongodb.mongoclient.connect('mongodb://1.1.1.1,2.2.2.2,3.3.3.3.', function (err, db) { if (err) { complete('{}'); } else { i distribute load of queries evenly across 3 instances of mongodb replica set instead of default having queries routed ec2 instance primary mongodb defined, because destroys point of load balancer (which balance load of queries across 3 instances evenly). my understanding when connecting mongodb replica set, primary instance selected unless primary instance down, , therefore purpose of every secondary instance serve backup. in example people call hot,cold,cold. because there 2...

c# - Randomly pick a specific int from a 2D Array -

i'm trying randomly specific integer (1) 2d array list filled 0's , not many 1's. made this, , works: while (wallslist[randomx, randomy] != 1) { randomx = randomizer.next(34); randomy = randomizer.next(34); } the downside of it, it's takes time find 1 time int (1), , have process on 1000 times since new 1's added , removed 2d array each time. takes 3m launch program know if there optimized version of this, searched lot , found solution 1d arrays. time. you have sparse array. why not represent list of x/y int pairs? then, if x/y int pair in list, it's 1, if not, it's 0. then, find random value/cell containing 1, pick random value list. you use list like new list <tuple<int, int>> { new tuple<int, int>(1, 5), new tuple<int, int>(2, 7) }
