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…

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…

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)

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…

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)
