raw_input returns a string. You need to convert it like this: int(raw_input(“Raise by: “)) Also, notice that if the user enters any other character this will raise an error. You can also just use input instead of raw_input: input(“Raise by: “) This will, again, raise an error if the user enters any other character. 2 … Read more
Given that the question you posed doesn’t have enough information, I’ve formulated an answer that implements the rules you wrote about. Unfortunately, it’s hard to validate this because the expected output you provided doesn’t follow the rules (e.g. 133344444,3,106029,106961,12981,3_1category). I’ve also made the assumption that if an NA value is found, it should be treated … Read more
Ah, I see you like Project Euler 🙂 Solution I think this is what you meant by your code: def square_of_sum(): sum_ = 0 for x in xrange(1, 11): sum_ += x return sum_ ** 2 To rewrite this more idiomatically, use generator comprehensions and built-ins: def square_of_sum(): return sum(range(11)) ** 2 If your performance … Read more
You convert the user’s input to a string (str(input(‘What …’))) but compare it to integers in inputCheck. Since there is no else path in inputCheck, nothing happens when you enter a “valid” choice. Also, if you’re using Python 2, using input is not what you want, raw_input is the way to go (see, for example … Read more
There are two issues: There is no = in between the variable continue and input() on line 21. You cannot use continue as a variable name, as it is a keyword, so basically you need to replace all those instances with another variable name. solved I am learning python and following along with a tutorial … Read more
Use Jython. It has a built-in compiler to convert .py files to .class, called jythonc. solved How do I convert my *.py files to *.class files? [closed]
Every integer is divisible by itself and by 1. If the integer is composite, it will have at least one other pair of divisors (which may be the same, as in the case of 4, which is divisible by 1,4 and 2,2). lim = int(math.sqrt(num)) for i in range (1, lim): if num%i==0: print(i, int(num/i)) … Read more
Even though it’s a homework question, you can do it as: [a%10 for a in l] 1 solved How can I calculate a list modulo a numer in python?
This isn’t working because you’re using globals. When you hit if tape[selectedCell] == int(”.join(num)): for the third if statement, nums contains [‘1’, ‘1’] because both if statements have added a 1 to num, so when you do int(”.join(num)) you end up with 11 which is not equal to 1. You need to refactor this code … Read more
All you have to do in this case is remove the int() call from the main(). Your string() function is expecting a string – if you send it an int, it’ll never work. Additionally, you can use the elif keyword: def string(x): if x==”1″: word = “one” elif x==”2″: word = “two” elif x==”3″: word … Read more
If you want to add a a value to key in your dictionary just make sure the values are, from the start, tuples or lists. Once you do this you can just: d = {1:(0,),2:(0,)} d[1] = d[1]+(0,) And a new value is now present at d[1]. Other than that and you might have to … Read more
My guess is that it’s a numpy array, not a list. This is logical indexing. The > comparison returns an array of booleans. Wherever those are True, the corresponding element of img is set to [0, 0, 255]. More directly, it’s creating a ring of blue points, where the radius of the inner empty circle … Read more
The simple way to get a count of unique words is to use a set. I put your text into a file called ‘qdata.txt’. The file is very small, so there’s no need to read it line by line: just read the whole thing into a single string, then split that string on whitespace and … Read more
def printLocations(s, target): ”’ s is a string to search through, and target is the substring to look for. Print each index where the target starts.

In order to give a good answer to jill1993’s question and take the MosesKoledoye’s answer : abproject = (“C:/abproject.build”) abproject is a string object. Furthermore, you write : with open(“C:/abproject.build”, “r+”) as script So if you want to solve your script error, you have to write : with open(“C:/abproject.build”, “r+”) as script, open (“C:/tempfile.build”,”w+”) as … Read more
