a. You specify a default parameter value by following a parameter’s name with an = and a value.
b. Any parameters with default parameter values must appear in the parameter list to the right of parameters that do not have defaults.
c. For the following call, the interpreter passes the default parameter value 3 for the width as if you had called rectangle_area(3, 10):
rectangle_area(10)
d. The following call to rectangle_area has arguments for both length and width, so IPython- ignores the default parameter values:
rectangle_area(10, 5)
Imagine a program that compresses files by 80 percent and stores them on storage media. Before the compressed file is stored, it must be divided into blocks of 512 bytes each. Develop an algorithm for this program that first reads the number of blocks available on the storage media. Then, in a loop, read the uncompressed size of a file and determine whether the compressed file will fit in the space left on the storage media. If so, the program should compress and save the file. It continues until it encounters a file that will exceed the available space on the media. For example, suppose the media can hold 1000 blocks. A file of size 1100 bytes will compress to size 880 and require 2 blocks. The available space is now 998 blocks. A file of size 20,000 bytes will compress to size 16,000 and
