Patricio Nicolas's questions

I am working with Python3 and Matplotlib and I want to put on each bar its corresponding value in Y. Is this possible?

Thanks.

How can I install pygame for python3 using pip? I have Python version 3.6.3.

I tried with pip install pygamebut it was installed on python 2.7.

Thanks.

I would like to know what is the most efficient way to compare the contents of two arrays, to do this in the least amount of time and to use the least amount of resources.

I present this example in Python of how I do it on a daily basis. For this example, there are few elements, it takes very little time, but as we add elements, the times increase exponentially.

If you want to give an example in another welcome language, the idea is to know the logic of how to do it over the language.

Here the example:

#!/usr/bin/python
# -*- coding: utf-8 -*-

arreglo1   = [1,2,3,4,5,6]
arreglo2   = [0,2,4,6,8,10]
repetidos  = []

for x in arreglo1:
    for y in arreglo2:
        if x == y:
            repetidos.append(x)

print "Los Repetidos son"
for z in repetidos:
    print z      

The output is: The Repeats are 2 4 6

Is there a function phpthat returns the number of times an element is repeated within a array?. If not, I'll have to iterate through each element and use a counter to see how many times it repeats.

Something like that, like the function count()that has Python. The output of that program would be 2, since the one is present twice in the array.
