Python Mod 2 Sec 2

Literals in Python represent fixed values assigned to variables or constants. The correct choice defines literals accurately, and 123 is a valid example of a numeric literal, as it is a direct representation of a number.

To convert the binary number 1010 to decimal, calculate: (1×2^3) + (0×2^2) + (1×2^1) + (0×2^0) = 8 + 0 + 2 + 0 = 10. Thus, the decimal equivalent of 1010 is 10.

The octal system uses base 8, while the hexadecimal system uses base 16. Therefore, the correct answer is B) 8 and 16.

An integer in Python is defined as a whole number, which can be positive or negative. The correct choice states that -5 is an example of a negative integer, accurately reflecting this definition.

True. Floating-point numbers in Python represent real numbers and include a fractional component, allowing for the representation of values like 3.14 or -0.001.

To encode an apostrophe in a string, you can use a backslash before it (e.g., 'It\'s a test'). This allows Python to interpret the apostrophe as part of the string rather than as a string delimiter.

In Python, the two constant objects used to represent truth values are 'True' and 'False'. These are the standard boolean values, while 'Yes', 'No', '1', '0', 'On', and 'Off' are not recognized as boolean constants.
