Python: Draw Flower

Drawing with Python

In this post i tried to draw another flower using arcs of circles, i get a simple one and i guess with more sizes we can do more complex shape.

You can play with the code and change the numbers, size and rotation degree and let’s see what we will have.

t = turtle.Turtle()
t.hideturtle()
t.pendown()
for x in range (30):

t.circle(60,70)

if x %3==0:

t.circle (10,90)

## Python Project

Python: Binary Search

Binary Search

Definition:

Binary Search is a search algorithm that finds the position of a target value within a sorted array. Binary search compares the target value to the middle element of the array.

In this code we are writing a Python code to find the target in a sorted given array and get its position without using any python math packages.

The case: We have an Array (arr=[2,3,5,6,8,10,11,13,15,16,19]) our target is 13, so we want the position of 13.

We are setting the first position as (pos_s=0) and the end position as (pos_e= the length of the array -1) and we will use recursive function.

Recursive Function: is a computer function or procedure that calling it self

The Code:

arr=[2,3,5,6,8,10,11,13,15,16,19]
target=11
pos_s =0
pos_e=int(len(arr)-1)
midarr =0
def bsearch(arr,target,pos_s,pos_e):

midarr=(pos_s+pos_e)/2

if arr[midarr] < target:

pos_s = midarr +1

bsearch(arr,target,pos_s,pos_e)

elif arr[midarr] > target:

pos_e = midarr -1

bsearch(arr,target,pos_s,pos_e)

elif arr[midarr] == target:

print(‘The target was: ‘,target, ‘ The key of our target is: ‘,midarr)

return

print(arr)
# Call the functin
bsearch(arr,target,pos_s,pos_e)

## Python : Expenditure App

Expenditure Application

leveling the Ground:

In this post we will assume that we have a folder for our application, and we will create two files one is for our python code and we will name it “expen.py”, the other is for our data and we will name it “expen_dat.json” this file extension is ‘json’. Also I assume that we have json pack is installed in the PC so if you don’t have json this is the time to install it.

json file:After you create expen_dat.json file just open it with any text editor and copy a test data of our expenditure as shown.

{“expenditure”:
[
{“date”:”02/03/2016″,”amount”:300},
{“date”:”10/04/2016″,”amount”:550},
{“date”:”02/05/2016″,”amount”:300},
{“date”:”10/04/2016″,”amount”:550},
{“date”:”02/03/2016″,”amount”:300},
{“date”:”10/04/2016″,”amount”:550},
{“date”:”05/01/2017″,”amount”:400},
{“date”:”10/02/2017″,”amount”:400},
{“date”:”15/03/2017″,”amount”:400},
{“date”:”20/04/2017″,”amount”:400}
}]

In next post we will start with coding and testing our Expenditure Application.

I will use the @pycharm to write the code and test it, but any other code editors can be used. Also, I assume we have Python and json installed in your PC.
