Understanding the use of basic file handling operations

    Cards (106)

    • 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
