Generally, take care of some pitfalls: set the executable flag on the script: chmod u+x test.py try to execute with a preceding dot “./”, so call ./test.py otherwise it might execute some other script from within your PATH also make sure you don’t have windows line endings, this seems to prevent the shebang evaluation, too. There are some suggestions around, e.g. in this answer, on … Read more
No, you can’t use multiple arguments. Python executes each + operator separately, the two + operators are distinct expressions. For your example, object + 1 + 2 really is (object + 1) + 2.

Use , to separate strings and variables while printing: , in print function separates the items by a single space: or better use string formatting: String formatting is much more powerful and allows you to do some other things as well, like padding, fill, alignment, width, set precision, etc. Demo:
For a short, fast solution that does the whole thing in one loop, without dependencies, the code below works great.
OK, two steps to this – first is to write a function that does the translation you want – I’ve put an example together based on your pseudo-code: You may want to go over this, but it seems to do the trick – notice that the parameter going into the function is considered to be … Read more
Looks like the problem is in this line. The key callable should take only one argument. Try:
You get this error message if a Python file was closed from “the outside”, i.e. not from the file object’s close() method: The line del f deletes the last reference to the file object, causing its destructor file.__del__ to be called. The internal state of the file object indicates the file is still open since f.close() was never called, so the destructor tries … Read more
Get data from the URL and then call json.loads e.g. Python3 example: Python2 example: The output would result in something like this:
You can define a rect as the area of the input box. If a pygame.MOUSEBUTTONDOWN event occurs, use the colliderect method of the input_box rect to check if it collides with the event.pos and then activate it by setting a active variable to True. If the box is active you can type something and Pygame will generate pygame.KEYDOWN events which have a unicode attribute that you can simply add to a string, … Read more
