my approach :
def merge_the_tools(string, k):
mylist = []
m = 0
for x in range(len(string)//k):
mylist.append(string[m:m+k])
m += k

for x in mylist:


btw thanks coding cart for the help! wouldn't have been done without your explanation!

[zerynn]

started python abt 2 weeks ago and this video helped me to realise to use "dict()" to remove the non-distinct characters! thanks
Heres my solution:
```import textwrap

def merge_the_tools(string, k):
t = textwrap.wrap(string, k)
for i in t:

Here's a diff approach :
from collections import OrderedDict

def merge_the_tools(string, k):
l = []
m=0
for i in range(len(string)//k):
l.append(string[m:m+k])
m= m+ k

for v in l:

[hureramujeeb]

My Solution:
def merge_the_tools(string, k):
while string:
s = string[0:k]
there = ''
for c in s:
if c not in there:
there += c
print(there)
string = string[k:]

may god bless you bro..great explanation

[darpanshrivastava]

After getting the substring and then converting it into a list, we could've use set() instead of creating a new dictionary and then again getting the key values. But again, I appreciate the explanation.

[sunillucky]

here the different apporach of merge tools
string=input()
k=int(input())
s=len(string)//k

m=0
empty_list=[]
for i in range(s):

m+=k
sub_str=empty_list
for v in sub_str:

print(dict_keys)

[tdyhuho]

Another Approach :

def merge_the_tools(string, k):
# your code goes here

w = len(string)
for i in range(1, int(w/k)+1):
lt = []
st = ''
new_string = string[k*i-k : k*i]
for j in new_string:
if j not in lt:
lt.append(j)
st = st + j
print(st)

if __name__ == '__main__':
string, k = input(), int(input())
merge_the_tools(string, k)

[piyushchaudhari]

Very nice approach bro...keep it up :)

[debojitmandal]

hi is it possible to use set insted of dict as set will anyhow remove the duplicates

[cricketh]

Very Good Explanation Sir, Are You Software Employee

[Cloudxxx]

Why hackerrank has to limit what you can do, how you will solve the problem? In the Merge The Tools problem, their given code can't be deleted. WTF!

[Cloudxxx]

Hi. You didn't explain why it need to convert to dictionary and the fromkeys method.🤔🤔😏😏

[dhruvtrivedi]

sir can we use set in this to remove duplicate

[surajthadarai]

Don't you check for the constraint as well?

[abrarmasumabir]

bro how did you get the number of lines in your jupyter notebook ....plz tell me

[bibekanandasahoo]

import textwrap
def merge_the_tools(string, k):
x=textwrap.wrap(string, k)
for i in x:

#### I just copy your code sir for making a list i use textwrap.wrap()

[reddyhimabindu]

sir can we use textwrap function for it

[debojitmandal]

here is my approach

s ='AABCAAADA'
m=0
k =3
l=[]
for i in range(len(s)//k):
l.append(s[m:m+k])
m = m+k
l
for v in l:
print(v)
z = set(v)
print(z)
result_string = ''.join(z)
print(result_string)
