Extending these closures gives us decorators, which are an invaluable asset.<br>To solve the above question, make a list of the mobile numbers and pass it to a function that sorts the array in ascending order. Make a decorator that standardizes the mobile numbers and apply it to the function.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Solution_%E2%80%93_Standardize_Mobile_Number_Using_Decorators_in_Python\"><\/span><strong>Solution &#8211; Standardize Mobile Number Using Decorators in Python<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<pre class=\"EnlighterJSRAW\" data-enlighter-language=\"python\" data-enlighter-theme=\"\" data-enlighter-highlight=\"\" data-enlighter-linenumbers=\"\" data-enlighter-lineoffset=\"\" data-enlighter-title=\"\" data-enlighter-group=\"\">def wrapper(f):\n    def fun(l):\n        # complete the function\n        f(['+91 ' + c[-10:-5] + ' ' + c[-5:] for c in l])\n    return fun\n\n@wrapper\ndef sort_phone(l):\n    print(*sorted(l), sep='\\n')\n\nif __name__ == '__main__':\n    l = [input() for _ in range(int(input()))]\n    sort_phone(l) <\/pre>\n\n\n\n<script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js\"><\/script>\n<ins class=\"adsbygoogle\"\n     style=\"display:block; text-align:center;\"\n     data-ad-layout=\"in-article\"\n     data-ad-format=\"fluid\"\n     data-ad-client=\"ca-pub-5246141430412355\"\n     data-ad-slot=\"8798433565\"><\/ins>\n<script>\n     (adsbygoogle = window.adsbygoogle || []).push({});\n<\/script>\n\n\n\n<p><strong>Disclaimer:<\/strong> The above Problem <strong>(<a href=\"https:\/\/www.hackerrank.com\/challenges\/standardize-mobile-number-using-decorators\/problem\" target=\"_blank\" rel=\"noreferrer noopener\" class=\"rank-math-link\">Standardize Mobile Number Using Decorators<\/a>)<\/strong> is generated by <strong>Hacker Rank<\/strong> but the Solution is Provided by <strong>CodingBroz<\/strong>.
