Does Haskell require a garbage collector?
...grams, the lifetime of an object can only be determined at runtime.
For em>x m>ample, consider the following program:
main = loop (Just [1..1000]) where
loop :: Maybe [Int] -> IO ()
loop obj = do
print obj
resp <- getLine
if resp == "clear"
then loop Nothing
else loop o...
How to invoke the super constructor in Python?

How to concatenate items in a list to a single string?
...
I kind of em>x m>pected sentence.join(" ") to work as well, since the reverse operation is list.split(" "). Any idea if this is going to be added to Python's methods for lists?

How do I get the row count of a pandas DataFrame?
...
You can use the .shape property or just len(DataFrame.indem>x m>). However, there are notable performance differences ( len(DataFrame.indem>x m>) is fastest).
Code to reproduce the plot:
import numpy as np
import pandas as pd
import perfplot
perfplot.save(

ImportError: Cannot import name m>X m>
...ld know that two classes should NEVER be dependant on each other. This is em>x m>tremely important in C++, and even if it's not the #1 thing in Python, it's still a really good idea to follow this rule. Never have two classes which know each other, ever. If you need help with creating the structure for y...
What is the difference between a string and a byte string?
...t encoding may map the same bytes to a different string:

Once you know which one to use, you can use the .decode() method of the b...
How to print (using cout) a number in binary form?

Chain-calling parent initialisers in python [duplicate]

The way you are doing it is indeed the recommended one (for Python 2.m>x m>).
The issue of whether the class is passed em>x m>plicitly to super is a matter of style rather than functionality. Passing the class to super fits in with Python's philosophy of "em>x m>plicit is better than implicit".

What is the difference between List (of T) and Collection(of T)?

In short, it's much easier to em>x m>tend it after the fact, which could potentially mean a lot less refactoring.
