I would not suggest giving a new python programmer decorator methods either; just define a function outside the class. It's the simplest to understand and a good habit to build first. Functions that don't act on the class object or the instance can be plain functions. Not harpin' on you for helping though.

Said friend here. This is how mine ended up. first time with python but i tried to cover all my bases. probably not the best

code:

def cif(words): 							#shifting cipher
	result, new_char = "", "" 					#declaring what I can
	for char in words:						#looping per each character in phrase
		cap = char.isupper()					#Checks if letter is captilized. Saves this in cap.
		ltr = ord(char.lower()) + shift 			#converts to lower-case as well as shifting the ascii number
		if ltr > 122: ltr -= 26  				#if it goes above the range of lower-case letters it loops it back
		elif ltr < 97: ltr += 26 				#if it goes above the range of lower-case letters it loops it back
		if char.isalpha(): 					#checks to see if char is an alphabetical letter
			if cap == True: ltr -= 32			#reverts ltr back to it's capitalized state
			new_char = chr(ltr)      			#assigns ltr in to char after reverting to character
		else: new_char = char					#if it is not an alphabetical letter it prints as is
		result += new_char					#joining characters back into string
	return result							#completes and returns string

You also need some blank lines for readability. I can't think of the studies right now to quote, but something like this:

Python code:

def cipher(words):                                    
    new_phrase = []

    for char in words:                                  
        uppercase_check = char.isupper()

        letter = ord(char.lower())
        letter += shift

        if letter > 122:                    #Preventing ASCII from over 'z'
            letter -= 26                   
        elif letter < 97:                   #Preventing ASCII from under 'a'
            letter += 26      
            
        if char.isalpha():
            if uppercase_check is True: 
                letter -= 32
    
            new_phrase.append(chr(letter))
        else: 
            new_phrase.append(char)                          

    return ''.join(new_phrase)

Your computer symlinks python3 to a Python 2 instance? That's a bit dubious. I'd do something about that, like installing Python 3.

So either you mistyped map in place of something else (like fov_map perhaps?) or you need to incorporate the code that defines map. In the unlikely event that this code does redefine a very basic and useful built-in function rather than simply coming up with a unique name, consider learning from another source because that's a huge red flag.

Poison Mushroom posted:

A class is a sort of blueprint for making an object or a function, something you'll need to do a lot. Classes are to functions as constants are to magic numbers. If I wanted to create a lot of gamemaps, then it would behoove me to make a Class for them, something to repeat the map-making code over and over. Something like Floor or Level.

So I'd put my map-generation code into that class under def __init__, and every time something from the code calls to create something from the Floor class, it'd run all the mapmaking code right then, with room to also include in the class possible variations on the formula? (Larger rooms, fewer rooms, a different tunnel generation process, etc?)

I do have control over the schema, but I've been making changes to it quite rapidly through a web admin tool, so it seemed easier to just reflect it rather than go through and update the code each time. address_data is simply the name of the table, and represents the table so that I can do things like:

Python code:

self.db_session.query(address_data).filter_by(addressref = self.addressref).first()

Address is then implementing some application logic, which also includes calls to the address_data table. Does that make sense?

Hey guys, I'm relearning python, and doing it via code academy. I'm trying to be dumb and do things a step above, and I suppose make it.. different? Dunno, trying things, but I can't remember if I can do a for loop like this:

I seem to recall a way to set the variable names within the for loop, so instead of item_weighted = foo, it actually comes out as homework_weighted = foo. Am I dumb and this can't be done?

It's been a few years since I did anything with Django but: it is that easy to just put Django in front of an arbitrary database and use it as the ORM for the site? I seem to recall Django being a bit pernicky about how db's were laid out. Of course, it depends on how complex the object are that you are pulling out and how polluted my memory is by all those frameworks that are really strict about database structure ("must be named foo_id and must be an integer ...")

Is there some peculiar reason why somebody might want to explicitly pass self into an instance method rather than call it from self directly? I can't imagine what's going on. I'm reading some code from somebody I initially was giving a lot of slack since he was generally doing decent software engineering conceptually. However, bells started to go off when I saw some Systems Hungarian Notation.
