Exercise7 || Solution

Write a Python algorithm that returns the list of divisors of a given integer. Example if n = 18, the algorithm returns the list [1, 2, 3, 6, 9, 18]

1. Creating a Label Widget

We have already seen how to create a label in the previous tutorial by importing the Label class:
from kivy.uix.label import Label

code to display a 'Hello World!' label

from kivy.app import App 
from kivy.uix.label import Label
class myApp(App):        
    def build(self):         
        lbl=Label(text='Hello World!')         
        return lbl      
myApp().run()



1. What is kivy?

Kivy is a free and open source library for Python, useful for building touch applications with a natural user interface. This library works on Android, iOS, GNU / Linux, OS X and Windows. It is distributed free of charge and under the MIT license. Kivy is the main framework developed by the Kivy organization, in parallel with Python-for-Android2, Kivy iOS, as well as several other libraries intended to be usable on all these platforms. The framework contains all the elements to build applications and in particular:
  1. Extended input functions for the mouse, keyboard, tangible user interfaces, as well as multi-touch events generated by these different devices.
  2. a graphics library based only on OpenGL ES2, and using Vertex Buffer Objects and shaders.
  3. a wide range of widgets supporting multi-touch.
  4. an intermediate language (Kv3), to easily build custom widgets.

Exercise 6

Write a Python algorithm that returns the length of a given list without using the len() method.

Solution

def lenList (L):
    # initialize the length of the list
    l = 0
    # browsing through all list elements 
    for x in L:
        # length increment
        l = l + 1
    return l

# Example
L = [11, 3, 5, 8, 2]
print ("the length of the list is:", lenList (L))
# The output is: the length of the list is: 5

Exercise 5

Given a list of integers L, write a program in Python that returns the sum of the list L elements.

Solution

# creation of a function which returns the sum of the elements of a list
def listSum (L):
    # initialization of the sum of the list elements
    s = 0
    for x in L:
        s = s + x
    return s

# Example
L = [2, 1, 5, 3]
# Display the sum of the list elements:
print ("The sum of the list element is:", listSum (L))
# The output is: The sum of the list L element is: 11

Solution

# initializing the list of numbers to enter
listNumbers = []
for i in range (0 , 5):
    n = int (input ("Type the value of an integer:"))
    # add the number n to the list
    listNumbers.append (n)
# Display the list of entered numbers:

Setting up an upload form within a django model

It often happens that you wish to add a file field to a registration or data insertion form ... So far we have not yet dealt with this type of field. The file field type can be treated either in isolation or within a model. To keep it simple, we are going to deal with this last type. 
Let's start by creating a mysite project in which we create an application named studentsApp

 
Next, let's create a directory named media within our mysite project. This folder must be configured within the file: 

Exercise 4

Write a Python program that asks the user to enter 5 integers of their choice and display the list of numbers entered.

Solution

# initialization of the list of numbers to enter
listNumbers = []
for i in range (0 , 5):
     n = int (input ("Type the value of an integer:"))
     # add the number n to the list
     listNumbers.append (n)
# Display the list of entered numbers:
print ("Here is the list of entered numbers:" , listNumbers)
