 | Here is a very different solution (the bitCount() function comes [from here](http://wiki.python.org/moin/BitManipulation), it counts the number of bits set in an integer) import random def bitCount(int_type): count = 0 while(int_type): int_type &= int_type - 1 count += 1 return(count) tails = bitCount(random.getrandbits(100)) :) It is probably much faster.  |
 | Try `print(pd)` to see where this pandas comes from. |
 | @urireo561 You can use pythonmagick or another imagemagick python binding to resize the image. See this snippet for example https://www.daniweb.com/programming/software-development/code/463880/resize-an-image-with-pythonmagick |

| | HTML is a special case of XML, the difference is that in an XML file, you can have arbitrary tags, like [icode]<nunos>hello</nunos>[/icode]. So, if a library can parse XML, it can also parse HTML and other specialisations of XML, like MATHML, etc. That's why most libraries are designed for XML. … |
| | [QUOTE=docdawning;1059689]Sure Python requires memory management, but if you provide a bare-metal type OS beneath the interpreter, somewhat like how BIOS provides a compatibility layer, then you could set out to write an OS that's extremely heavily implemented with Python. Still, doing so would require an intimate understanding of the plumbing … |
| | I suppose that you can obtain the implementation of `ioctl()` by downloading the source code of the `glibc` library [http://ftp.gnu.org/gnu/glibc/](http://ftp.gnu.org/gnu/glibc/).  |
 | see [this thread](http://www.daniweb.com/software-development/python/threads/463434/pyqt4-problem). It looks like the same issue. |

| | Because as you defined it, send_SMS is a method of the class sendmessage. So when you call [icode]x.send_SMS('error')[/icode], 2 arguments are passed, the first is [icode]x[/icode], the other is [icode]'error'[/icode]. There are 2 solutions, either you add an argument: [icode]def send_SMS(self, message):[/icode], or, if you don't need the instance, you … |
 | Perhaps a `sudo apt-get install python-pyside` (or python3-pyside). |
| | I would use [code=python] Calculate = sum [/code] instead of the above code ;) |
| | Standard builtin functions have been tested gazillion times by programs all around the world. It is almost impossible that you discover an unknown bug in them. `strip()` removes characters only at both ends of the string. You will have to use `replace()` >>> 'qazxswedc'.replace('x', '') 'qazswedc'  |

 | I don't think it's correct to blame Google for Q&A sites' success. I think these sites meet a specific programmers' need: we want to use software and libraries and we don't have time to learn APIs or read every manual. So we need expert answers to specific use cases. The … |

 | The problem is that you write `from tkinter import *` after `from graphics import *`. Some objects defined in the [graphics.py](https://pypi.org/project/graphics.py/) package get shadowed by objects defined in the tkinter package. In this case, the graphics.py [Text](http://mcsp.wartburg.edu/zelle/python/graphics/graphics/node11.html) class is shadowed by the tkinter [Text](http://infohost.nmt.edu/tcc/help/pubs/tkinter/web/text.html) widget.

| | The first thing is to never have variable names containing a variable index, such as `product_1, product_2,` etc. Use lists or tuples instead pairs = [ ("Flake", 0.55), ("Wispa", 0.50),("Crunchie", 0.65), ("Milky Way", 0.35), ("Boost", 0.65) ] product, product_price = zip(*pairs) Then `product[0]` is `'Flake'`,` product[4]` is `'Boost'` and similarly … |

 | Before even thinking of using python for this, you need to define what the computer will do and what the human player(s) will do. You don't need a specific programming language for this. |
| | Unindent the ask_number() and ask_yes_no() definitions and remove the self parameter.  |
 | In python 3, the value returned by `binascii.hexlify()` is a `bytes` instance instead of a `str` instance. As `setText()` is expecting a `str` instance, you need to convert hexadecimal to `str`. This is done by hexa_str = hexadecimal.decode('utf-8') |

| | @sam_38 Your question is way too vague. The best way to use a programming forum is to start your own thread and post code containing your attempts to solve the problem. If your question is about persisting data on disk, there is a builtin module `pickle` that can persist almost …  |
 | Strange code and strange specifications as usual, but well ... Two points: 1. Why do you want the vector to hash as a tuple ? What's the use of this ? There must be a good reason as this breaks your code. 2. There is a serious drawback in your … |
 | The `sorted()` function has a boolean `reverse` parameter that allows to sort in descending order sorted(lines, key=itemgetter(3), reverse=True) This is much more efficient than trying to write your own quicksort method.  |
 | For problem 1, I think you could remove the 'data' argument in def OnCellChange(self, evt, data): ... For problem 2, you need to compute the `row` value that you want to insert, for exemple def appendRow(self): row = self.GetNumberRows() # + 1 perhaps ? self.AppendRows(1) self.data.append((str(row), '', '', '', '', … |

| | Hi Tcll, it's been a while indeed! I don't think there is a flaw in python's descriptor implementation. Also I don't understand why you think there is a security issue nor which 'private object' is 'passed into your backend'. If Attr is a descriptor in the class, then indeed `Instance.Attr` … |
| | Hi, it's been a long time since I last used wxpython, but I think it should be something like for i, seq in enumerate(data): for j, v in enumerate(seq): self.SetCellValue(i, j, v) You should find good examples in the Mouse vs Python series, which cover many things concerning wx python, … |
 | Re: python **What have you tried?** This is what everybody wants to know when you ask a homework question. We don't know what you know about programming in python. Obviously you must have learned how to define a function, that's a starting point. Let's take it the other way around. If I …  |
