Python File Handling

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

  1. Open a FileUse the open() function, specifying the filename and mode:
    file = open('filename', 'mode')
  2. Specify the ModeChoose a mode, such as ‘r’ for reading or ‘w’ for writing.
  3. Reading or Writing to the FileTo read or write, use:
    content = file.read()
    file.write('Hello, world!')
  4. Close the FileDon’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)
