Complete the method/function so that it converts dash/underscore delimited words into camel casing. The first word within the output should be capitalized only if the original word was capitalized.

Examples:

to_camel_case("the-stealth-warrior") # returns "theStealthWarrior"
 to_camel_case("The_Stealth_Warrior") # returns "TheStealthWarrior"

#python #codewars

name = 'Is-this-a-tough_question?'
 name[0] + name.title().translate(None, '-_')[1:]

OR:

name = 'Is-this-a-tough_question?'
 name.title().replace('-', '').replace('_', '')

Write a function, which takes a non-negative integer (seconds) as input and returns the time in a human-readable format (HH:MM:SS)

HH = hours, padded to 2 digits, range: 00 - 99
 MM = minutes, padded to 2 digits, range: 00 - 59
 SS = seconds, padded to 2 digits, range: 00 - 59

راه حل دوست خوبمون Mehrshad:

toh = lambda n: "{}:{}:{}".format(str(n//3600).zfill(2), str((n%3600)//60).zfill(2), str((n%3600)%60))

نکته ای که هست میشود با string formatter بجای zfill پیش رفت:

return '{:02}:{:02}:{:02}'.format(s / 3600, s / 60 % 60, s % 60)

If you forget to pull your projects from git in a regular interval and many users working on the same projects, then there is a solution for you!

Create a bash script file as follow and make it executable by chmod +x puller.sh:

puller.sh file content:

#!/bin/bash

 echo 'Iterating over folders...'
 for dir in *
 do
   test -d "$dir" && {
       cd ${dir}
       echo "git pull $dir"
       git pull
       cd ".."
   } || {
       echo "------> $dir is not a directory <-------"
   }
 done

NOTE: this file should reside in your folder's project root. In my case it is in /Your/Projects/Folder.

Now as a final step, put it in your crontab:

10 * * * * bash -c "cd /Your/Projects/Folder; bash puller.sh >> /var/log/git_pull_output.log"

#linux #git #pull #cronjob #crontab #cron #bash

Count the number of Duplicates

Write a function that will return the count of distinct case-insensitive alphabetic characters and numeric digits that occur more than once in the input string. The input string can be assumed to contain only alphabets (both uppercase and lowercase) and numeric digits.

Example:

"abcde" -> 0 # no characters repeats more than once
"aabbcde" -> 2 # 'a' and 'b'
"aabBcde" -> 2 # 'a' occurs twice and 'b' twice (`b` and `B`)
"indivisibility" -> 1 # 'i' occurs six times
"Indivisibilities" -> 2 # 'i' occurs seven times and 's' occurs twice
"aA11" -> 2 # 'a' and '1'
"ABBA" -> 2 # 'A' and 'B' each occur twice

What is your solution?

#python #codewars

from itertools import groupby

def duplicate_count(a):
    return len([1 for k, i in groupby(sorted(a.lower())) if len(list(i)) > 1])

We have talked before about how to get current month using the below line of code:

echo $(date +%m)

It prints out 01, 02, etc.

As per the GNU date manpage:

By default, date pads numeric fields with zeroes. The following
    optional flags may follow '%':
    - (hyphen) do not pad the field

So you can remove leading zero by hyphen as below:

echo $(date +%-m)

It prints out 1, 2, etc.

#linux #bash #date

As an alternative to the pprint module:

# The standard string repr for dicts is hard to read:
>>> my_mapping = {'a': 23, 'b': 42, 'c': 0xc0ffee}
>>> my_mapping
{'b': 42, 'c': 12648430. 'a': 23}  # 😞


# The "json" module can do a much better job:
>>> import json
>>> print(json.dumps(my_mapping, indent=4, sort_keys=True))
{
    "a": 23,
    "b": 42,
    "c": 12648430
}

# Note this only works with dicts containing
# primitive types (check out the "pprint" module):
>>> json.dumps({all: 'yup'})
TypeError: keys must be a string

#python #pprint #json #dumps

A Narcissistic Number is a number which is the sum of its own digits, each raised to the power of the number of digits in a given base. Here we will restrict ourselves to decimal (base 10).

For example, take 153 (3 digits):

1^3 + 5^3 + 3^3 = 1 + 125 + 27 = 153

and 1634 (4 digits):

1^4 + 6^4 + 3^4 + 4^4 = 1 + 1296 + 81 + 256 = 1634

The Challenge:

Your code must return true or false depending upon whether the given number is a Narcissistic number in base 10.

NOTE: Error checking for text strings or other invalid inputs is not required, only valid integers will be passed into the function.

#python #question #codewars

from math import pow

def narcissistic(value):
    digits = map(int, list(str(value)))
    power = len(digits)
    final_res = 0
    for digit in digits:
        final_res += pow(digit, power)
    return int(value) == int(final_res)

#python #solution

def narcissistic(value):
    return value == sum(int(x) ** len(str(value)) for x in str(value))

#python #solution

The maximum sum subarray problem consists in finding the maximum sum of a contiguous subsequence in an array or list of integers:

maxSequence([-2, 1, -3, 4, -1, 2, 1, -5, 4])
 # should be 6: [4, -1, 2, 1]

Easy case is when the list is made up of only positive numbers and the maximum sum is the sum of the whole array. If the list is made up of only negative numbers, return 0 instead.

Empty list is considered to have zero greatest sum. Note that the empty list or array is also a valid sublist/subarray.

How do you sort the below object based on the value in Javascript?

{
     "en": "English (English)",
     "fa": "French",
     "ar": "العربیه",
     "zh": "中文 (Chinese)"
 }

Well first you need to make an array of arrays:

var sortable_langs = [];
 $.each(languages, function(index, language) {
     sortable_langs.push([index, language]);
 });

 sortable_langs.sort(function(a, b) {
     if(a[1] < b[1]) { return -1; }
     if(a[1] > b[1]) { return 1; }
     return 0;
 });

NOTE: a[1] and b[1] refers to the language value like: English (English). They are compared with each other. If a[1] is bigger than b[1] then it will be moved to the first to the top.

In-place value swapping

# Let's say we want to swap
# the values of a and b...
a = 23
b = 42

# The "classic" way to do it
# with a temporary variable:
tmp = a
a = b
b = tmp

# Python also lets us
# use this short-hand:
a, b = b, a

How to get only numbers in textbox using jQuery?

// Restricts input for each element in the set of matched elements to the given inputFilter.
 (function($) {
     $.fn.inputFilter = function(inputFilter) {
     return this.on("input keydown keyup mousedown mouseup select contextmenu drop", function() {
         if (inputFilter(this.value)) {
         this.oldValue = this.value;
         this.oldSelectionStart = this.selectionStart;
         this.oldSelectionEnd = this.selectionEnd;
         } else if (this.hasOwnProperty("oldValue")) {
         this.value = this.oldValue;
         this.setSelectionRange(this.oldSelectionStart, this.oldSelectionEnd);
         }
     });
     };
 }(jQuery));

 // restrict input to receive just numbers
 $("#my_input_num").inputFilter(function(value) {
     return /^\d*$/.test(value);

In Google OAUTH 2.0 in case you get a token from Google Login you can get user's information for that token by sending a simple GET request to the following URL:

https://www.googleapis.com/oauth2/v1/userinfo?alt=json&access_token=YOUR_GOOGLE_TOKEN

The response differs based on the given scope on the first login step. Mine was set to the below:

https://www.googleapis.com/auth/plus.me https://www.googleapis.com/auth/userinfo.profile https://www.googleapis.com/auth/userinfo.email
