Hello,

I am looking for the most efficient way of writing a program of array with binary values (0s and 1s) to find a row with max number of 1s. For example if row 3 has max 1s then output should print row = 3

Hi there, I'm Dan from Deepnote. We're a small startup creating a better data science notebook compatible with Jupyter and one of the things we're really interested is making it easier for people to try and learn from existing projects. I was trying out Deepnote with some interesting public repos, including yours and since I already set it up for myself, I thought it might be useful for others too to have a one-click button to run your repo, so I submitted a PR. Compared to binder, Deepnote offers more advanced features like collaboration or persistent environment so people can save their progress and come back to it later.

Hope you find it useful, and thanks for your work!

For Question 3, Corrected an existing solution

'''Solution by: yurbika '''

num = int(input("Number: ")) print(dict(list(enumerate((i * i for i in range(num+1)))))) #incorrect: output produced starts from {0: 0, 1: 1, ......}

print(dict(enumerate([i*i for i in range(1, num+1)], 1))) #correct: output produced starts from {1: 1, 2: 4, .......}

Question 9: Write a program that accepts sequence of lines as input and prints the lines after making all characters in the sentence capitalized.

Suppose the following input is supplied to the program:

Hello world Practice makes perfect

My answer is given below:

x = input()

print(str(x).upper())

Hi,

So I have cleaned up the formatting of all Days_*.md files and fixed some random errors wherever I found them. Additionally, I have created a notebooks folder with all 24 days as jupyter notebooks. I have taken the liberty to remove all Python 2 solutions considering the problem of running Python 3 and 2 together in a notebook and also considering the end of support for it. I have strived to retain as much original content as possible and have formatted it black and tried to fix some variable naming with PEP8 conventions.

The jupyter notebooks can be accessed directly via the binder link added on the README.

Why this code behave in such a strange way?

Here is the problem:

Write a program which accepts a sequence of comma separated 4 digit binary numbers as its input and then check whether they are divisible by 5 or not. The numbers that are divisible by 5 are to be printed in a comma separated sequence.

Example:

0100,0011,1010,1001

Then the output should be:

1010

Notes: Assume the data is input by console.

Here is my solution:

resultat equals to sum of values, multiplied by their symbols

values start from 1 and doubles for each next symbol

symbols can be only 1 or 0

binary_numbers = input('Write a sequance of comma and whitespace(, ) separated 4 digit binary numbers(0,1): ').split(', ')

for number in binary_numbers: value = 1 res = 0 for digit in number[::-1]: res += int(digit) * value value *= 2 # print(res) if (res % 5) == True: binary_numbers.remove(number)

print(', '.join(binary_numbers))

so, if we print out "res"s, with "0100, 0011, 1010, 1001" as input, we would have 4, 3, 10, 9 as output

and out for:

print(bool(4 % 5)) print(bool(3 % 5)) print(bool(10 % 5)) print(bool(9 % 5))

will be:

True True False True

so, it should work, but it doesn't

I assumed, that problem is in the list removing and wrote this piece of code:

ml = ['asdasd', 'dfdffdf', 'ssdsdfsdfsdfsdfdfdfddd', 'asdasdasdssssss']

for item in ml: print(item, len(item)) if len(item) > 6: ml.remove(item)

and, all of a sudden, it doesn't work too, the output is:

asdasd 6 dfdffdf 7 asdasdasdssssss 15 ['asdasd', 'ssdsdfsdfsdfsdfdfdfddd']

but length of the third(2) item of a list is obviously bigger than 6, so, looks like this code has been completely skipping the 'ssdsdfsdfsdfsdfdfdfddd' value. Further more, if we comment out the "if" block, it will see this value in the list and print its length

in:

ml = ['asdasd', 'dfdffdf', 'ssdsdfsdfsdfsdfdfdfddd', 'asdasdasdssssss']

for item in ml: print(item, len(item)) # if len(item) > 6: # ml.remove(item)

out:

asdasd 6 dfdffdf 7 ssdsdfsdfsdfsdfdfdfddd 22 asdasdasdssssss 15

I completely don't inderstand what is going on between for loop and conditional if statement.

Is anybody knows?

For Question 3:

def integral(num):
temp_list=[item for item in range(1, num)] return { item: item*item for item in temp_list}

inputs = int(input("Please a number")) integral(inputs)

in this program every second string is being saved and every odd string is skipped.

Solution: change while input(): to while True: and it will be solved like below:

Why do every second line is storing in the list and all odd lines are skipped?

lst = []

while True: x = input() if len(x) != 0: lst.append(x.upper()) else: break

print(lst) for line in lst: print(line)
