I have textmate, but honestly the only thing I can do with it is simply edit a file. The handy little file browser is aslo useful. (how can I show/hide that file browser anyhow!) But I have no other knowledge/tricks up my sleeve, care to help me out? ...

What's the best way to install two python modules with the same name? I currently depend on two different facebook libraries: pyfacebook and Facebook's new python-sdk. Both of these libraries install themselves as the module 'facebook'. I can think of a bunch of hacky solutions but before I go an hack away I was curious if there was a py...
Hi, I'm using twisted.internet.serialport to have my program be continuously connected to a device on a serial port. Unfortunately my serial port is just a usb device, which means it can be disconnected or reset by the OS at any time (port 2 disabled by hub (EMI?), re-enabling... ). I see that pyserial has support for this for a few we...
Hi, I have several very large zip files available to download on a website. I am using Flask microframework (based on Werkzeug) which uses Python. Is there a way to show the contents of a zip file (i.e. file and folder names) - to someone on a webpage - without actually downloading it? As in doing the working out server side. Assume t...
I have two lists, the first of which is guaranteed to contain exactly one more item than the second. I would like to know the most Pythonic way to create a new list whose even-index values come from the first list and whose odd-index values come from the second list. # example inputs list1 = ['f', 'o', 'o'] list2 = ['hello', 'world'] #...

I have a list [5, 90, 23, 12, 34, 89] etc where every two values should be a (ranked) list in the dictionary. So the list above would become {1: [5, 90], 2: [23, 12], 3: [34, 89]} etc. I've gotten close with list comprehension but haven't cracked it. I tried: my_list = [5, 90, 23, 12, 34, 89] my_dict = dict((i+1, [my_list[i], my_list[i...
I'm writing a Google app engine app and obviously the default web app framework is a subset of Django. As such I'm using it's templating engine. My question is if I have say the following code: template_values = { 'first':first, 'second':second, } path = os.path.join(os.path.dirname(__file__), 'index.html') self.resp...
How does: dict = {} if key not in dict: dict[key] = foo Compare to: try: dict[key] except KeyError: dict[key] = foo ie, is the look up of a key in anyway faster than the linear search through dict.keys(), that I assume the first form will do? ...
Hi, I'm quite new to python (I use python 3), and i'm trying to serialize a class with one string and two lists as members in JSon. I found that there's a json lib in the python standart but it seems that I need to manually implement a serialization method. Is there a JSon encoder where I can simply pass an object, and receive the serial...
If I understand correctly, the __cmp__() function of an object is called in order to evaluate all objects in a collection while determining whether an object is a member, or 'in', the collection. However, this does not seem to be the case for sets: class MyObject(object): def __init__(self, data): self.data = data def _...
I have a compiled Python library and API docs that I would like to use from Ruby. Is it possible to load a Python library, instantiate a class defined in it and call methods on that object from Ruby? ...
I'm running a Django application on Apache with mod_wsgi. Will there be any downtime during an upgrade? Mod_wsgi is running in daemon mode, so I can reload my code by touching the .wsgi script file, as described in the "ReloadingSourceCode" document: http://code.google.com/p/modwsgi/wiki/ReloadingSourceCode. Presumably, that reload requ...
As I work and update a class, I want a class instance that is already created to be updated. How do I go about doing that? class MyClass: """ """ def __init__(self): def myMethod(self, case): print 'hello' classInstance = MyClass() I run Python inside of Maya and on software start the instance is created. When I call classInst...
I have a table with several dependent tables that I want cascade delete. I'm having problems with it cascading too far. Some code will help explain. class Map(Base): .... #One to many relationship between the Map and Tile. #Each Map is made up of many tiles tiles = relationship('Tile', lazy='joined', backref='map', ...
I needed to write a weighted version of random.choice (each element in the list has a different probability for being selected). This is what I came up with: def weightedChoice(choices): """Like random.choice, but each element can have a different chance of being selected. choices can be any iterable containing iterables w...
What I'd like to achieve is the launch of the following shell command: mysql -h hostAddress -u userName -p userPassword databaseName < fileName From within a python 2.4 script with something not unlike: cmd = ["mysql", "-h", ip, "-u", mysqlUser, dbName, "<", file] subprocess.call(cmd) This pukes due to the use of the redirect symb...
Hi, After much research, I've come up with a list of what I think might be the best way of putting together a Python based social network/cms, but have some questions about how some of these components fit together. Before I ask about the particular components, here are some of the key features of the site to be built: a modern almo...
When I print the tuple (u'1S²') I get the predicted output of 1S² However, when I print the tuple (u'1S²',u'2S¹') I get the output (u'1S\xb2', u'2S\xb9'). Why is this? What can I do about this? Also, how do I get the number of items in a tuple? ...
