 | Re: String help I used a for loop just for a little variety. And I would also think it should be (but that is just my opinion) [CODE]p p l l aa <-- not reversed cc <-- reversed e e s s [/CODE] |
| | [QUOTE]tuple_dict = {} receives "TypeError: unhashable type: 'list'"[/QUOTE] I would suggest that you print the values and note also that a list can not be used as a dictionary's key. If that is indeed what you want to do, convert to a tuple first. [CODE]def histogram(s): tuple_dict = {} ## … |

| | The "self.deck.deal([player])" would be a good place to check except self.deck, self.deck = BJ_Deck(), does not have a deal() function. Generally you want to check every time before you deal or hit as you will also catch it if the burn card or the hit card reduce the deck to … |

| | What does the function normDistProb return? The first attempt to debug this should be to print it [CODE]for i in range(0,12): listProbFog.append(normDistProb(dayValues[i], fogAve[i], fogVar[i])) print normDistProb(dayValues[i], fogAve[i], fogVar[i]) print listProbFog # the other lists are just extra cruft until you get this problem solved [/CODE] |
| | Re: variable Image [QUOTE=;][/QUOTE] You have to retrieve and store the RadioButton object. This code stores the grid() object: [CODE]# Radiobutton(canvas, variable=xy, value=x,command=self.move).grid(row=row,column=column) # # instead use # self.rb =Radiobutton(canvas, variable=xy, value=x,command=self.move, image=xxx.) self.rb.grid(row=row,column=column) # using "row" and "column" as names is confusing # # and then self.rb.configure(image=yyy) [/CODE]For configure options see [url]http://www.astro.princeton.edu/~rhl/Tcl-Tk_docs/tk/button.n.html[/url] |
| | [QUOTE=;][/QUOTE] Split() each record. Don't use the first element of the list, join([1:]), in the first file. And, similarly, don't use the last element in the second file. |
| | [QUOTE=;][/QUOTE] [QUOTE]there are 31 days in the month so i'm trying to take the last 5 days in this case[/QUOTE]That would be something along the lines of: [CODE]print range(32)[-5:][/CODE] |

| | Try it the other way around? [CODE]inCur = gp.SearchCursor(myFeatureClass2,'COLLECTED_BY = "%s"' % (str(Name)), \ "", "", "DATE_COLLECTED A") [/CODE]Generally, the name is also stored as "obrien" so you can find O'Brien, O'brien, Obrien, etc. I don't know if this is possible here or not. |
 | Also, form the habit of using a list instead of if/elif. It is more straightforward as all of the conditions are on one line. And verb[-2:] is just shorthand for verb[-2:len(verb)], just as verb[:-2] is shorthand for verb[0:-2]. [CODE]verb = input("Write the verb here: ") if verb[-2:] in ['ar', 'er', … |
| | [QUOTE=;][/QUOTE] A second dictionary is not required. Create a tuple containing item1 and item2 and look up in the dictionary. If found, you have a match. If you want to keep the keys in the same order as the file, use the [URL=http://code.activestate.com/recipes/107747-ordered-dictionary/]ordered dictionary[/URL]. For Python 2.7 it is in … |
| | If you are confident that the string is not wrap- ped around (on 2 lines), then reading the file one record at a time and searching it is the accepted way to go. You have to look at every character in the file no matter how you do it.  |
| | You must install the version of PIL for the Python version that you have on your system. You are trying to install PIL for Python2.6. Python2.6 can not be found on your system. Keying "python -V" (capital V, not lower case) on the command line will give you the Python … |

| | [QUOTE=;][/QUOTE] You never exit the "while True" so it is an infinite loop. Once you eliminate that, you should be able to print the final word_list list which will be a series of numbers. Sort the list and count each of the sequences of the same number. You should also …  |

| | [QUOTE=;][/QUOTE] You want to start testing at the third element & checking the prior two. What you have will error because when the last element is reached, there is no +1 (also do not use "i", "l", or "O" as single digit variables as they can look like numbers). [CODE]## … |
| | You should state what it is you want to do. No offense but there are other solutions and perhaps someone here can come up with a workable solution. Generally you would use (although I can't really understand what you are asking): [CODE]class myClass: def __init__(self, methodName="This is the result"): self.methodName … |
| | [QUOTE=;][/QUOTE] Isn't nodeTable a list of classes? So you would access it like this: [CODE] for node in nodeTable: #if node != 0 and Node.visited == False: #nearestNode = node[theNetwork] #listOfNeighbours.append(nearestNode) print node.distFromSource, node.previous. node.visited [/CODE]That is if your class is constructed correctly, which it is not, so that is … |

| | Split on "study", or a normal split on space(s) will also work as the number.txt will be -1, or the study's description will be everything except the last element. |

| | You can't combine grid() and pack() but must use one or the other. Also, AFAIK, one radio button must be selected (a default selection or you can't choose 'none' when using radio buttons), and the others can be deselected. [CODE]from Tkinter import * class App: def __init__(self, parent): self.my_parent = … |
 | You will have to put trace points in your program to see where it is hanging. I doubt it is here. Also, do not use "list" as a variable name as it is already used to name a function that returns a list, and that could be the problem because …  |

| | Run the input files one at a time, i.e. run the program using the first file and check the output, then run the program again using the second file and check the output file, etc. |

| | The health variable would be the same as the location and inventory variables. Using a class makes this simple. Instead of "money", "rope", "shiny_stone", etc. I would suggest using a dictionary.

| | [QUOTE]try and convert the value from the numctrl to a decimal[/QUOTE]You can not convert a float to decimal.Decimal because floats are inaccurate past a certain number of digits. You will have to get/enter the value as a string and convert. |

| | join() interleaves a list with a constant so self.currentOutDir.join(self.counterStr) would produce self.counterStr[0]+self.currentOutDir+self.counterStr[1]+self.currentOutDir+self.counterStr[2]...etc. A simple example: [CODE]x = ["1", "2", "3"] print "a".join(x) # x = "123" print "b".join(x) [/CODE] |
