How deeply does Python Workout, Second Edition cover numeric base?

Explains int’s base argument and practices bases 2–16, without detailing numeral-system internals.

Numeric base

As explained in Python Workout, Second Edition

A number base is the radix that determines the positional values of digits in a numeral system.

A numeric base determines how Python interprets digit characters when converting a string to an integer. Pass the base as int’s optional second argument. section 2.15

The same input, different bases

The string "10" can represent different values: int("10", 2) interprets it as 2, while int("10", 16) interprets it as 16. A hexadecimal conversion therefore passes 16 explicitly. section 2.15 section 2.5

Use numeric bases as practice problems:

Extend a guessing game so each round selects a random base from 2 through 16 and interprets the user’s input accordingly. section 2.5
Reimplement conversion without int, using ord and chr to recognize legal characters for the selected base. section 2.17
