Hackerrank_Solution_Blank_File_Creator Problem

The script 'Hackerrank_Solution_Blank_File_Creator' is designed to automate the process of creating blank Python files for solving problems on Hackerrank. It reads problem titles and subdomain names from a text file, then creates a new directory for each subdomain and generates a blank Python file for each problem within the appropriate subdomain directory.

Here is the Hackerrank_Solution_Blank_File_Creator Problem HackerRank solution using CodeRankGPT:

The script works by first reading lines from a text file. Each line either contains a problem title or a subdomain name. The script then checks if a directory for the subdomain exists, and if not, it creates one. It then generates a valid filename for each problem, creates a new Python file with that name in the appropriate subdomain directory, and writes a header to the file containing the problem title, subdomain, domain, author, and creation date. The script uses regular expressions to validate and clean up the problem titles and subdomain names.


import datetime
import os
import re
import sys

extension = ".py"
domain = "Python"
author = "Ahmedur Rahman Shovon"
created_date = datetime.datetime.today().strftime("%d %B %Y")
info_file_name = "python_info.txt"

def valid_name(given_name):
    return re.sub(r"[^\w]", "", given_name)

def write_file_header(title, subdomain):
    header_str = "''\n"
    header_str += "Title     : " + title + "\n"
    header_str += "Subdomain : " + subdomain + "\n"
    header_str += "Domain    : " + domain + "\n"
    header_str += "Author    : " + author + "\n"
    header_str += "Created   : " + created_date + "\n"
    header_str += "''\n"
    return header_str

problem_list = ""
subdomain_name = ""

info_file = open(info_file_name, "r")
info_file_lines = info_file.readlines()
info_file.close()
for line in info_file_lines:
    line = line.strip()
    if line == "":
        continue
    elif line[0] == "[":
        problem_list = line
    else:
        subdomain_name = line
    if subdomain_name != "" and problem_list != "":
        folder_name = valid_name(subdomain_name)
        if not os.path.exists(folder_name):
            os.makedirs(folder_name)
        title_ar = re.findall(r'("[^"]*")', problem_list)
        title_ar_len = len(title_ar)

        for title in title_ar:
            file_header_str = write_file_header(title[1:-1], subdomain_name)
            title_valid = valid_name(title)
            f = open(folder_name + "\\" + title_valid + extension, "w")
            f.write(file_header_str)
            f.close()

        print("Folder: " + str(folder_name) + ". Total files: " + str(title_ar_len))
        subdomain_name = ""
        problem_list = ""
