Python: Print using ascii codes -

i'm beginner in python , i'm having problem in program:

here's nodelist first:

class node:     def __init__(self,initdata):         self.data = initdata         self.next = none      def getdata(self):         return self.data      def getnext(self):         return self.next      def setdata(self,newdata):         self.data = newdata      def setnext(self,newnext):         self.next = newnext 

my problem in program: (the print)

from nodelist import node  class stackll:      def __init__(self):         self.head = none      def pushsll(self,item):         temp = node(str(item))         temp.setnext(self.head)         self.head = temp         node = self.head         print(chr(0x2510)+(chr(0x0000)*(len(item)))+chr(0x250c))         while node!=none:             stackeditem = chr(0x2502)+node.data+chr(0x2502)             print(stackeditem)             node = node.next            print(chr(0x2514)+(chr(0x2500)*(len(item)-1))+chr(0x2518)) 

everytime print, lines seems off. tried experiment using len() make accurate, everytime item adds more characters gets off again. appreciated. thank you.

use monospace font @kable answered.

in addition that, last print print 1 less chr(0x2500).

some other notes:

• use \u2502 instead of chr(0x2502).
• separate dump functionality pushsll.
• the first , last print consider length of current node. should calculate maximum length nodes.

class stackll:      def __init__(self):         self.head = none      def pushsll(self, item):         temp = node(str(item))         temp.setnext(self.head)         self.head = temp      def dump(self):         length = max(len(node.data) node in self.allnodes()) if self.head else 0         print('\u2510{}\u250c'.format(' '*length))         node in self.allnodes():             print('\u2502{:<{}}\u2502'.format(node.data, length))         print('\u2514{}\u2518'.format('\u2500'*length))      def allnodes(self):         node = self.head         while node not none:             yield node             node = node.next  s = stackll() s.pushsll('arc') s.pushsll('circle') s.pushsll('rect') s.dump()
