Вот пример записи в файл на Python 3, а также некоторые другие методы и примеры кода:

1. Использование метода write():

   # Open the file in write mode
   file = open('example.txt', 'w')
   # Write data to the file
   file.write('Hello, World!')
   # Close the file
   file.close()

2. Использование метода writelines():

   # Open the file in write mode
   file = open('example.txt', 'w')
   # Write multiple lines to the file
   lines = ['Line 1\n', 'Line 2\n', 'Line 3\n']
   file.writelines(lines)
   # Close the file
   file.close()

3. Использование функции print()с параметром file:

   # Open the file in write mode
   file = open('example.txt', 'w')
   # Redirect the print output to the file
   print('Hello, World!', file=file)
   # Close the file
   file.close()

4. Использование оператора with:

   # Open the file in write mode using 'with' statement
   with open('example.txt', 'w') as file:
   file.write('Hello, World!')

5. Использование метода write()в двоичном режиме:

   # Open the file in binary write mode
   file = open('example.bin', 'wb')
   # Write binary data to the file
   data = bytearray([0x48, 0x65, 0x6c, 0x6c, 0x6f])  # 'Hello' in ASCII
   file.write(data)
   # Close the file
   file.close()
