In Python 2 and code that must be cross-version compatible, just stick to passing in the class object and instance explicitly. Yes, there are “backports” available that make a no-argument version of super() work … Read more
I simplified the test a bit – if all(x%y instead of if not any(not x%y I also limited y’s range; there is no point in testing for divisors > sqrt(x). So max(x) == 100 implies max(y) == 10. For x <= 10, y must also be < x. Instead of generating pairs of primes and … Read more

Use not
Is there any function in numpy to group this array down below by the first column? I couldn’t find any good answer over the internet.. Wanted output:
I really can’t see any good reason not to just suppress the warning. The safest way would be to use the warnings.catch_warnings context manager to suppress the warning only where you anticipate it occurring – that way you won’t miss any additional RuntimeWarnings that might be unexpectedly raised in some other part of your code: … Read more
Use str.replace. Alternatively use re and use regular expressions. This will allow the removal of leading/trailing spaces.
You need to add it to an axes. A Circle is a subclass of an Patch, and an axes has an add_patch method. (You can also use add_artist but it’s not recommended.) Here’s an example of doing this: This results in the following figure: The first circle is at the origin, but by default clip_on … Read more
In order to set a general default value for all keys, you can use defaultdict:
I’m programming a spellcheck program in Python. I have a list of valid words (the dictionary) and I need to output a list of words from this dictionary that have an edit distance of 2 from a given invalid word. I know I need to start by generating a list with an edit distance of … Read more
