C) Allow the user to specify the upper limit, instead of always using 100. (d) Have your program sound confident by predicting the maximum number of guesses it will take. The log() and ceil() functions from the math module may be helpful. py that calculates the number of years it will take to reach a savings goal given a starting principal and interest rate. Write appropriate functions, ask the user for input, and display the result. Hint: use an accumulator rather than a formula. 15 Write the function intlog2(n) that returns the largest integer k such that 2k ≤ n.

In this chapter, we begin to develop an answer by looking at how integers are stored. Bits and Bytes Computer memory of all types may be thought of at different levels of interpretation. The bottom level is electronics and physics, which is taught in those courses. We will move up one level of interpretation and begin by thinking of memory as a sequence of electronic on/off switches. Each on/off switch is called a bit. A group of 8 bits is called a byte. In abbreviations, a small “b” refers to bits, while capital “B” refers to bytes.

Body> Selection: If Statements 31 An if statement may contain an optional else clause, which contains alternative code to run when the boolean expression is False: if : else: In this case, is executed if the boolean expression is True; otherwise, is executed. Finally, a sequence of tests may be checked by using the elif option: if : elif : elif : ... else: Here, if is True, then is executed; otherwise, is evaluated, and if it is True, is executed; and so on.
