Understanding the use of basic file handling operations

• In programming, file handling refers to the ability to interact with files on a computer's file system
• The 'Write' operation in file handling adds or modifies data in the file.


  True
• Proper file handling, including opening, reading/writing, and closing files, is an essential programming skill
• Reading a configuration file is an example of using file handling to restore user preferences.

  True
• Steps for opening a file in Python

  1️⃣ Specify the file path

  2️⃣ Choose a file mode

  3️⃣ Use the open() function
• Steps for opening a file in programming

  1️⃣ Specify the file path

  2️⃣ Choose a file mode

  3️⃣ Use the `open()` function
• What does the `read()` method do when reading from a file?

  Reads the entire file content
• The `read()` method is best for small files where you need the entire content at once.


  True
• Data persistence allows data to be stored and retrieved even after the program is closed.


  True
• Steps for opening and closing a file in programming

  1️⃣ Specify the file path

  2️⃣ Choose a file mode

  3️⃣ Use the `open()` function

  4️⃣ Close the file with `.close()`
• The `read()` method is best for small files where you need the entire content at once.


  True
• When writing to a file, it must be open in write or append mode.


  True
• Ensuring the file is open in write or append mode is a best practice.


  True
• Match the method with its description:

  `write()` ↔️ Writes a single string to the file

  `writelines()` ↔️ Writes a list of strings to the file
• What is the purpose of a file access mode when opening a file?

  Determines how the file can be used
• The `r+` file access mode opens the file for both reading and writing
• What function is used to open a file in Python?

  open()
• It is essential to close a file after completing operations to release system resources.


  True
• The `writelines()` method writes a list of strings to the file
• The four basic file handling operations are open, read, write, and close
• The read operation is used to retrieve data from a file
• What is the main purpose of file handling in programming?

  Store and retrieve data
• To open a file for reading, you use the file mode `"r"`
• The `read()` method reads the entire file content
• The 'Read' operation in file handling retrieves data from the file
• Storing user preferences is a common use of file handling in programming.


  True
• Match the benefit of file handling with its description:

  Data Persistence ↔️ Stored data remains even after the program is closed

  Data Management ↔️ Enables organization and sharing of data

  Data Exchange ↔️ Facilitates import and export of data
• In programming, opening a file establishes a connection between the program and the file
• To close a file in Python, you must call the `.close()` method
• Closing files prevents data corruption and ensures efficient resource management.


  True
• Match each file reading method with its description:

  read() ↔️ Reads the entire file content

  readline() ↔️ Reads one line at a time

  readlines() ↔️ Reads all lines into a list
• The primary purpose of file handling in programming is to persistently store and retrieve data.
• To close a file in programming, you call the .close() method on the file object.
• The `readline()` method is useful for processing files line by line.
• The `writelines()` method is suitable for writing multiple strings from a list.
• `write()` is best for writing individual strings, while `writelines()` is suitable for writing multiple strings from a list
• The two main methods for writing to files are `write()` and `writelines()`, which differ in how they handle strings
• A file path specifies the directory structure to access a file.


  True
• Order the primary file handling operations:

  1️⃣ Open a file

  2️⃣ Read from a file

  3️⃣ Write to a file

  4️⃣ Close a file
• Match the method with its description for writing to files:

  `write(str)` ↔️ Writes a single string to the file

  `writelines(list)` ↔️ Writes a list of strings to the file
