Classes Python and developing Stack -


i have created own lifo container class stack supports methods of push, len, pop, , check on isempty. methods appear working in example calls, except when call created instance of class(in example s) receive memory location created object when want see actual contents of object.

class stack:     x = []      def __init__(self, x=none):         if x == none:             self.x = []         else:             self.x = x      def isempty(self):         return len(self.x) == 0     def push(self,p):         self.x.append(p)     def pop(self):         return self.x.pop()     def __len__(self):         return(len(self.x))       s = stack()         s.push('plate 1')     s.push('plate 2')     s.push('plate 3')     print(s)     print(s.isempty())     print(len(s))     print(s.pop())     print(s.pop())     print(s.pop())     print(s.isempty())

i result of running line print(s) <__main__.stack object @ 0x00000000032cd748>t when expect , looking ['plate 1','plate 2','plate3']

you need override __str__ or __repr__ if want class have different representation when printing. like:

def __str__(self):     return str(self.x)

should trick. __str__ called str function (and implicitly called print). default __str__ returns result of __repr__ defaults funny string type , memory address.

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers
