Alright I’ve done the hard part hoping you can finish it up: tmp = [] def recal(_list): n = [] if ‘-‘ in _list: for i in 0,1: t = _list[:] t[t.index(‘-‘)] = i n.append(recall(t)) else: tmp.append(l) return l recall([‘-‘,’-‘,’0′,’1’]) for l in tmp: print int(”.join(l),2) 0 solved combinations program help in python [closed]

If this is python3.x you have to do it as follows: if game_list[game]>= 10: print (“The Price for this Game is: $”, game_prices[game]*1.1) For python2.7, it would be: if game_list[game]>= 10: print “The Price for this Game is: $”+game_prices[game]*1.1 solved How to show the cost of a game using this Python [closed]
Aside from several ugly antipatterns, there’s one obvious mistake/typo: Take a good look at if a > 0: kb = int(str(byte)[a:b]) else: kd = int(str(byte)[0:b]) Do you see now where your error comes from? 1 solved What is wrong with this programming? [closed]
Just use zip to get tuples of values at corresponding indices in the two lists, and then cast each tuple to a list. So: [list(t) for t in zip(list1, list2)] is all you need to do. Demo: >>> list1 = [“X”, “Y”, “Z”] >>> list2 = [1, 2, 3] >>> list3 = [list(t) for t … Read more

num is not actually used in multiply() so there is no reason to pass it in. Instead, declare multiply() without the argument: def multiply(): ”'(num1 * num2)”’ . . And call it from __main__ like this: if maths == “Multiplication” or “m” or “x”: multiply() There seems no point in checking within multiply() whether it … Read more

For anyone curious, I quickly wrote a function for it. First off, the complete matching is written as a 2D list. The following function is needed before writing the main one: def index_2d(myList, v): #Returns tuple containing the position of v in the 2D list for i, x in enumerate(myList): if v in x: return … Read more
The answers in the comments are more pythonic, but if you want a more easily understandable example >>> books = {} >>> line = “Calculus | James Stewart” >>> parts = line.split(‘|’) # can also do title, author = line.split(‘|’) >>> books[parts[0].strip()] = parts[1].strip() >>> print(books) {‘Calculus’: ‘James Stewart’} 1 solved How can I produce … Read more

The easiest way to print the lines of codes is through the use of the built-in functions. print open(__file__).read() Or you could just write the code in string mode and simply print them. However that obviously won’t be executable codes anymore once written in quotation marks. solved How to print the codes in python? [duplicate]
