My Fitbit Data

Solving My Fitbit data Problem
Subject: VBA code to combine Fitbit excel files into one

I purchase a Fitbit Alta HR in 2017, and since then I wear it and never take it off unless for charging. Fitbit Alta HR is a very nice slim device, but unfortunately there was no way to upload my previous data from my old device to my Fitbit, this was not the only issue with Fitbit data, now; after three years still we can’t download Fitbit data in one file, if you want to do this (each time) you need to send a request to Fitbit team and they will prepare the file for you!! Instead, Fitbit site allow you to download your data as month by month, in my case I will have almost 32 files.

Solving the Problem: After downloading the excel files and look at them, I decide to write a code to help me combine all the current 32 files and any coming once into one data file. First I start thinking to use Python to do this task, but after second thought I will use the Excel file and VBA macro coding to do it.
Here in coming paragraph I will post about the general idea and some codes that i use.

General Idea: I will use same structure of Fitbit file and name it as “fitbit_All_data_ali”, in this file we will create new tab and name it Main. In the Main tab we will create several buttons using excel developer tools and will write the macro VBA code for each task we need to operate.

Tabs in our file: Main: Contain buttons and summary about my data.
Body, Food, Sleep, Activities and Food Log. Food Log tab will store the data such as calories, fibers, fat and so-on., all those tabs will be filled with a copied data from each Fitbit data file.

Here are some VBA codes that I use and what it’s purpose .

Code:
‘ Get current path.
the_path = Application.ActiveWorkbook.Path
The path on the current excel file.
Code:
the_All_Data_file = ThisWorkbook.Name
Get current excel file name
Code:
Workbooks.Open Filename:=thepath + my_source_Filename
Open a file
Code:
Windows(my_source_Filename).Activate
Sheets(“Foods”).Select
Range(“A2:B31”).Select
Selection.Copy
Goto fitbit file, goto food sheet, select the data copy it.
Code:
Application.CutCopyMode = False
Workbooks(my_source_Filename).Close SaveChanges:=False
Close an open excel file.
Code:
Range(“A3”).Select
Selection.EntireRow.Insert , CopyOrigin:=xlFormatFromLeftOrAbove
To insert a black Row
Code:
sname = ActiveSheet.Name
Get current sheet name
Code:
Function go_next_sheet() As String

‘ This code will go to next sheet if there is one, if not will return ‘last’
go_next_sheet = “no”
Dim sht As Worksheet
Set sht = ActiveSheet

On Error Resume Next

If sht.Next.Visible xlSheetVisible Then
If Err 0 Then
go_next_sheet = “last”
End If

Set sht = sht.Next
End If

sht.Next.Activate
On Error Resume Next

End Function

if there is no more tabs or sheets, function will return “last”


Final Results: After i run the code, I have an Excel file contain all my Fitbit data in one place. Mission Accomplished

Python: Smallest Multiple



Python: Smallest multiple
Problem 5 @ projecteuler
Completed on: Thu, 4 Jul 2019, 22:30

Here I am quoting form ProjectEuler site:”

2520 is the smallest number that can be divided by each of the numbers from 1 to 10 without any remainder. What is the smallest positive number that is evenly divisible by all of the numbers from 1 to 20?”


So to solve this simple task all we need to loop through numbers and divide it by a list of (1,20) if yes return True otherwise return False and got to another number.
and so we done..

Python: Largest Palindrome Product



Python: Largest Palindrome Product
Problem No.4 @ Projecteuler
Complete on: on Fri, 5 Jul 2019, 08:53

The task was to find the largest palindromic number that been generated from multiplying two of 3 digits number.

Definition: Palindromic numbers are numbers that remains the same when its digits are reversed. Like 16461, we may say they are “symmetrical”.wikipedia.org

To solve this I first wrote a function to check if we can read a number from both side or not, Then using while and for loop through numbers 100 to 999, and store largest palindromic, we select the range (100,999) because the task is about tow number each with 3 digits.



The Code:



# Problem 4
# Largest palindrome product

palin =0
def palindromic(n) :

n_list=[]

for each in str(n) :

n_list.append(each)

n_last = len(n_list)-1

n_first =0

x=0

while (n_first+x != n_last-x) :

if n_list[n_first+x] != n_list[n_last-x] :

return False

else :

x +=1

if (n_first +x > n_last -x):

return True

return True

for set1 in range (1,999):

for set2 in range (set1,999):

if palindromic(set1 * set2) :

if (set1 * set2) > palin :

palin =(set1*set2)

print(‘\n We found it:’,palin, ‘coming from {} * {}’.format(set1,set2))

Python: Number Letter Counts



Python: Number Letter Counts
Problem 17, Projecteuler

For problem 17, projectEuler ask for the total numbers of alphabetics in all words of numbers from 1 to 1000.

Here I am coping from there page.

Once I read the task, I decide to create my own version of the requirement. I start to assume that I may have a dictionary with some numbers and words, then base on what ever the user will input (number between 1 and 999) then I shall convert it to words.

Example:
1 –> one
8 –> eight
234 –> tow hundred thirty-four .. and so on.


I start searching the net to get the words I need, and store them in 3 dictionaries.

num_1_9 = {“1″:”one”,”2″:”two” .. ext.
num_10s = {“10″:”ten”,”20″:”twenty” .. ext.
num_11s = {“11″:”eleven”,”12″:”twelve”.. ext


Then, I start writing the functions for each group of numbers/dictionaries, so if the user enter a number we will read number of digits if it is 1 then we call def num_1_d(), if it is 2 digits we call def num_2_ds() and if it is 3 digits we call num_3_ds(). At the end, we got the right answer for Projecteuler, and here is the code in my way, I am asking the user to enter a number then i convert it to a corresponding words.

Python: 10001st Prime
Problem No.7 @ ProjectEuler

This is one of shot projects you may find on ProjectEuler, the task is find the prime No 10001, I just run my is_prime function, if the number is prime will add 1 to the counter, until we reach 10001, that will be the answer.



The Code:

def is_prime(num):

result = True

for t in range (2,num):

if num%t==0 :

result= False

break

return result

p_count=0
num =0
while p_count <=10001:

num +=1

if is_prime (num):

p_count +=1

print(p_count,num)

Python: 1000-Digit Fibonacci



Python: 1000-Digit Fibonacci
Problem No.25, ProjectEuler

Another easy fast 5-minites task on projecteuler that Playing around Fibonacci Numbers, the task is to find the first Fibonacci index to contain 1000 digits.

So we will write a function to get the fibonacci numbers and each time we will check if it’s digits reach 1000, if not we will go for generating the next number.



The Code:



#1000-digit Fibonacci number
# problem no 25
# Solved.

def get_fibonacci():

x=1

fibo=[1,1]

while len(str(fibo[x])) != 1000:

fibo.append(fibo[-2]+fibo[-1])

x +=1

print(‘The index of the first term in the Fibonacci sequence to contain 1000 digits is ‘,x+1)

# Call the function

Python: Even Fibonacci Numbers
ProjectEuler Problem No.2

Easy fast task in ProjectEuler, The Task is to find the sum of the even-valued terms in Fibonacci sequence whose values do not exceed four million.

In this code we will add some print-statment to just show how mane even numbers there and the summation of it.



The Code:

def get_fibonacci_sequence():

n1 = 1

n2 = 1

fibo = 1

while fibo < 4000000:

fibo = n1+n2

n1 = n2

n2 = fibo

if fibo% 2 == 0:

even_fibo_num.append(fibo)

tot = 0
even_fibo_num = []

print(‘\n We fond {} even fibonacci”s number less than 4000000.’.format(len(even_fibo_num)))
