  It is a function name.
• What is a function in programming?

  A separate part of the computer code.
• What can a function cause in programming?

  It can send text to the terminal.
• How do Python functions relate to mathematical concepts?

  They evaluate values like mathematical functions.
• What forms the function invocation in Python?

  Function name, parentheses, and arguments.
• What do quotes do in a string in Python?

  They assign a different meaning to the code.
• What happens to data inside quotes in Python?

  It is taken literally, not as code.
• What is prohibited in a single line of Python code?

  Having more than one instruction.
• What is an exception to the rule about instructions in Python?

  One instruction can spread across multiple lines.
• What does an empty print() invocation output?

  An empty line or a newline.
• What is the escape character in Python?

  The backslash (\).
• What does the escape character do in a string?

  It introduces a special inclusion.
• What does the letter 'n' after the backslash represent?

  Newline.
• What is a newline character?

  A special symbol urging a new output line.
• What must you do to include a single backslash in a string?

  Double it (\\).
• What happens if you use a single backslash incorrectly?

  It will cause an error.
• How are arguments separated in the print() function?

  By commas.
• What role do commas play in the print() function?

  They are part of Python's syntax.
• What does the print() function do with multiple arguments?

  Outputs them all on one line.
• How does the print() function separate outputted arguments?

  It puts a space between them automatically.
• What is a keyword argument in Python?

  It consists of a keyword, equal sign, and value.
• Where must keyword arguments be placed in a function?

  After the last positional argument.
• What does the default behavior of the end keyword argument do?

  It is implicitly set to end="\n".
• What happens when the end argument is set to an empty string?

  No newlines are sent to the output.
• What can the string assigned to the end keyword argument be?

  Of any length.
• What does the sep keyword argument do in the print() function?

  It changes how arguments are separated.
• What can the sep argument's value be?

  It may be an empty string.
• Can keyword arguments be mixed in one invocation?

  Yes, they can be mixed.
• What is a literal in programming?

  Data whose values are determined by itself.
• What are the two types of literals mentioned?

  String and integer number.
• How are strings and integers stored in memory?

  Strings are series of letters; integers are bits.
• What types of numbers do modern computers handle?

  Integers and floating-point numbers.
• How do you code negative numbers in Python?

  By adding a minus sign.
• What are floating-point numbers designed to represent?

  Numbers with a non-empty decimal fraction.
• How can you write the value of zero point four in Python?

  As 0.4.
• What happens if you omit zero in front of or after the decimal point?

  You can omit it when it's the only digit.
• How does Python treat the numbers 4 and 4.0?

  4 is an integer; 4.0 is a float.
• What notation can be used for very large or small numbers?

  Scientific notation.
• How is scientific notation represented in Python?

  Using E or e for exponent.
