File CRUD Application - Python Project #07 - Project #29

 File CRUD Application:

    I created a file CRUD application that will create, read, update or delete any file. I created it using Python.

Code:

  import os
import time

# Reader class to read the file
class Reader:
    def __init__(self, fileToRead):
        self.file = fileToRead

    def readFile(self):
        try:
            with open(self.file, "r") as file:
                data = file.read()

            print(f"Data at {self.file} is below: \n")
            print(data)
            print("\nPress any key to return to menu")
            input()

            # If user typed file not present in the directory.
        except FileNotFoundError:
            print("Your file not found in the directory. Please check name of file and try Again.")
            print("Press any key to return to menu")
            input()

# Deleter class to delete the file
class Deleter:
    def __init__(self, fileToDelete):
        self.file = fileToDelete
    
    def deleteFile(self):
        try:
            action = input(f"Are you sure that you want to remove {self.file}? Yes/No: ")
            if action in ["Yes", "yes", "y", "Y"]:
                os.remove(self.file)
                print(f"\nYour file {self.file} Deleted Successfully")
                print("\nPress any key to return to menu")
            input()

            # If user typed file not present in the directory.
        except FileNotFoundError:
            print("Your file not found in the directory. Please check name of file and try Again.")
            print("\nPress any key to return to menu")
            input()

# Modifier class to modify a file
class Modifier:
    def __init__(self, fileToModifiy):
        self.file = fileToModifiy

    def modifyFile(self):
        try:
            data = input(f"Enter the data you want to write into {self.file}")
            with open(self.file, "r") as file:
                previousData = file.read()

            with open(self.file, "w") as file:
                file.write(data)
            print("\nData written successfully")
            print("\nPress any key to return to menu")
            input()
            # If user typed file not present in the directory.
        except FileNotFoundError:
            print("Your file not found in the directory. Please check name of file and try Again.")
            print("\nPress any key to return to menu")
            input()

class Creater:
    def __init__(self, fileName):
        self.name = fileName

    def createFile(self, data):
        with open(self.name, "w") as file:
            file.write(data)
        print("File Created Successfully")
        print(f"Data has been written to {self.name} Successfully")
        print("\nPress any key to return to menu")
        input()


# Main file class for running functions and take input from user and give to their specific classes
class File:
    def readFile(self):
        self.file = input("Enter the path of the file you want to read: ")
        return self.file

    def deleteFile(self):
        self.file = input("Enter the name of the file you want to delete: ")
        return self.file
    
    def modifyFile(self):
        self.file = input("Enter the path of file you want to modify: ")
        return self.file

    def createFile(self):
        self.name = input("Enter the name of file you want to create. (With Extension): ")
        return self.name

    def dataInFile(self):
        self.data = input("Enter data you want to put in file: ")
        return self.data
