According to the official Python page for the complexity of algorithms over time, the sequences list and set have the following characteristics:
List

I have an array of values that can include several numpy.nan:
import numpy as np
a = np.array ( [1, 2, np.nan, 4] )
And I want to iterate over your items to create a new array without np.nan.
The way I know to create arrays dynamically...
In R , there is a lot of freedom and variety in function names between packages. Names with dot ( get.this ), names with camelCase ( getThis ), names with underline ( get_this ). This has its pros and cons: but the fact i...
In probability theory, the birthday paradox says that given a group of 23 (or more) randomly chosen people, the chance that two people will have the same birthday is over 50%. For 57 or more people, the probability is greater than 99%, however, i...
I need to do a series of operations involving binary files (you can not use BD), and I need to ensure that they finish successfully even in the middle of the operation. To do this, I see no way out but to implement a journaling system manuall...
I have seen in some codes written in Python the following statement:
from __future__ import print_function
What is the purpose of this __future__ module? When do I need to import it into a script I'm doing?
Why is it, unlike th...

I did a question regarding a Python algorithm, but in resolution of the user Anderson Carlos Woss he used a type of% inline that I had never seen and that left me confused.

What are the differences between Tuple and List in Python ?
Example:
>a = [1, 2, 3]
# [1, 2, 3]
>b = (1, 2, 3)
# (1, 2, 3)
The Tuple , grotesquely speaking, is a constant that accepts List ?
