Python File Handling

To open and handle files in Python, you can follow the steps below:

1. Open a File

   Use the open() function, specifying the filename and mode:

   file = open('filename', 'mode')

2. Specify the Mode

   Choose a mode, such as ‘r’ for reading or ‘w’ for writing.

3. Reading or Writing to the File

   To read or write, use:

   content = file.read()

   file.write('Hello, world!')

4. Close the File

   Don’t forget to close the file when done:

   file.close()

Here is an example of file handling in Python:

# Writing to a file
with open('hello.txt', 'w') as f:
    f.write('Hello, world!')

# Reading from a file
with open('hello.txt', 'r') as f:
    content = f.read()
    print(content)
