QUESTION
I've started to learn Python programming using Learn Python the Hard Way. Exercise 3 has some math practice, for example:
...ANSWER
Answered 2018-Sep-02 at 10:20In Python3, the print statement of Python2 was changed to function: print(...). So Python2 interprets this Python3 statements as calling the print statement with a tuple.

I have been going through learn python hard way exercise 50,it is basically about building a small website,the complete problem statement available in below link exercise-50 ( [https://learnpythonthehardway.org/book/ex50.html][1])
I have created the app.py file in the specified directory and compiled the app.py .This is my app.py file

Answered 2017-Jun-17 at 15:02Seems you just forgot the ()at the end of your app.run() statement

The complete code is here http://learnpythonthehardway.org/book/ex43.html
My main question is the part of code below:
...ANSWER
Answered 2017-May-17 at 08:39The Scene baseclass doesn't define a custom equality test, so current_scene != last_scene falls back to a default: testing if two references point to one and the same object, instead.
You created a new Finished() instance, and it will always be un-equal to every other Finished() instance, including what self.scene_map.next_scene(next_scene_name) returns:
QUESTION
Having looked at How do you check in python whether a string contains only numbers? , I am aware that string.isdigit() is an effective way to test if a string contains only digits and nothing else. I am using Python 2.7.
However, when I try to use it in the following code, my program crashes with an "invalid literal for int() with base 10" error when I input any mix of numbers and non-numbers, e.g. "fsd7sfd" or similar. (The code works fine with either number-only strings or alpha-only strings.)
I don't understand how this is happening, since as far as I can tell, the assignment of "how_much = int(choice)" should never happen unless the string only contains digits in the first place, when choice.isdigit() is True.
Can someone help me understand what I'm missing?
As a side note, that "print "test"" line doesn't seem to get processed before the error either, which adds to my confusion.
(I'm trying to improve the "gold_room()" function from https://learnpythonthehardway.org/book/ex35.html , the rest of the code is there for reference.)

Answered 2017-Apr-14 at 21:14I am unsure why this is failing, but in my guess the more pythonic way of doing this is via a try except statement to catch a value error:

...ANSWER
Answered 2017-Feb-22 at 16:10Not all consoles support the \b character as a deletion character, especially graphical ones.
(same thing happens when you write it to a file, the previous char is not deleted either)
Try your example in a native shell (Windows or Linux would work) and the characters will be properly deleted.

QUESTION
I'm trying to find out what's going on here. I'm running through Learn Python the Hard Way book, and it got to the point where it wanted me to type out complex math: like those speed-math problems you may have gotten in elementary school. The problem is when I run the problem in the file from console, it produces an answer different than what you would find if you typed the problem into the console directly.
My example being thus:
The first line is the problem with the result that comes from the file being the following line. Then I replicate the exact same problem within the console to get the following result.
The site is insinuating that one would assume to see the number round down, while the author says it's truncating the number, or "dropping the fractional part after the decimal". I see neither of those things happening.
Can anyone tell me what's going on here? I currently have Python 2.7 installed.
...ANSWER
Answered 2017-Jan-15 at 11:34Both operands in 1/4 are integers. Python doesn't auto-convert the result of that operation to float. PowerShell does. Hence Python subtracts 0, whereas PowerShell subtracts 0.25.
