wonderly gonzalez's questions

I have a problem when trying to create an apk from my .py file created with the kivy framework, the error and the commands I use are the following

 wonder@wonder-M720SR:~/Kivy-Calculator$ buildozer android debug 

deploy run

# Check configuration tokens
# Ensure build layout
# Check configuration tokens
# Preparing build
# Check requirements for android
# Install platform
# Apache ANT found at /home/wonder/.buildozer/android/platform/apache-ant-1.9.4
# Android SDK found at /home/wonder/.buildozer/android/platform/android-sdk-20
# Android NDK found at /home/wonder/.buildozer/android/platform/android-ndk-r9c
# Check application requirements
# Check garden requirements
# Compile platform
# Command failed: /usr/bin/python3 -m pythonforandroid.toolchain create --dist_name=myapp --bootstrap=sdl2 --requirements=kivy --arch armeabi-v7a --copy-libs --color=always --storage-dir=/home/wonder/Kivy-Calculator/.buildozer/android/platform/build
# 
# Buildozer failed to execute the last command
# If the error is not obvious, please raise the log_level to 2
# and retry the latest command.
# In case of a bug report, please add a full log with log_level = 2

executing the command that generated the problem I receive this result:

wonder@wonder-M720SR:~/Kivy-Calculator$ /usr/bin/python3 -m pythonforandroid.toolchain create --dist_name=myapp --bootstrap=sdl2 --requirements=kivy --arch armeabi-v7a --copy-libs --color=always --storage-dir=/home/wonder/Kivy-Calculator/.buildozer/android/platform/build

Thanks in advance

I have a problem in c++ I am trying to do a simple calculation using OOP but the result is wrong and not close to what it should be:

#include <iostream>

using namespace std;

class productos{

public:

productos(int x,int y){
x=n;
y=m;
cout<<x*y;
}
int producto1(){

    return n*m;//Usando esta funcion tampoco arroja el resultado
}



private:
int m; 
int n;
int mil;




};
int main()
{
    productos dos(2,2500);



return 0;
}

The result is:

-1074975852-1074975852

It also gave me an error initializing:

int m=2500; 

I am a beginner in c++ and I have other practically identical console programs, maybe with more functions but basically the same.

What did I do wrong? and how do i fix it?

PS: I already tried with sublime text codeblocks and an online compiler and the result is the same.

I've been learning how to create Gui in python with Tkinter for almost a week. When creating free space around or creating a box and determining the dimensions of the widget using the container, Frameyou cannot modify the attributes such as padding, borderwidhtor widht.

This is my code:

from tkinter import *
from tkinter import ttk

root=Tk()

mainframe=ttk.Frame(root, ).grid()
mainframe['padding']=(5,10)#esta linea es la que me genera problemas y es de igual forma si quiero usar borderwidht o widht
etiqueta=ttk.Label(root,text="try").grid(row=0, column=2)
buton=ttk.Button(mainframe,text="push here",command=root.quit).grid(row=1, column=24)

root.mainloop()

and the result is:

Traceback (most recent call last):
 File "/home/wonder/PycharmProjects/untitled/essays tkinter.py", line 8, in <module>
   mainframe['padding']=(5,10)
TypeError: 'NoneType' object does not support item assignment

What am I doing wrong?
