# FILE लिखना
with open("notes.txt", "w", encoding="utf-8") as f:
    f.write("यह मेरी file है।\n")
    f.write("Python बहुत आसान है!\n")

# FILE पढ़ना
with open("notes.txt", "r", encoding="utf-8") as f:
    content = f.read()
    print(content)

# Line by line
with open("notes.txt", "r", encoding="utf-8") as f:
    for line in f:
        print(line.strip())

# Append करना
with open("notes.txt", "a", encoding="utf-8") as f:
    f.write("नई line!\n")

import os

# File exist check करना
if os.path.exists("notes.txt"):
    print("File मिली!")
    size = os.path.getsize("notes.txt")
    print(f"Size: {size} bytes")

# File delete करना
# os.remove("notes.txt")

# Directory बनाना
# os.mkdir("new_folder")

# सब files list करना
files = os.listdir(".")
print(files)
