a ____ is a horizontal or vertical bar that appears when the contents of an area may not be visible completely on the screen.

1 answer:

5 0

The answer is a Scroll bar, the description fits perfectly because you need to move it to see more of the content you are viewing, and it wont be completely. when the item does appear completely on screen then the bar is relatively large and there is no need for scrolling, however the opposite occurs during when you cannot see all of it.

Answer:

D). Algorithm

Explanation:

The set of specific, sequential steps that describe exactly what a computer program must do to complete the work is called an algorithm.

From the question, it is clear the correct option is algorithm.

In simple terms, to solve a problem the set of rules to follow is called algorithm. Algorithm in computer programming describes the steps that explains not only the task that needs to be performed, but also how to do it.

In algorithm, the steps are needed to be in the right sequence.

A) How could you modify Shelve with a technique discussed in class so that you can create Shelve instances that contain // Tools

Kay [80]

Answer:

See explanation

Explanation:

A “shelf” is a dictionary-like object. A shelf is an arbitrary Python objects, that is; anything that the pickle module can handle. This includes recursive data types and objects containing lots of shared sub-objects. It must be noted that the keys are ordinary strings.

(A). modification to Shelve can be done by following this instructions;

(1). Do not redefine built-in functions,(2). grab shelved item, mutate item, write mutated item back to shelf.

The number (2) instructions is during iteration over shelved items.

(B). CREATING FUNCTIONS THAT TAKES IN TWO SHELVES;

import shelve

d = shelve.open(filename) # open -- file may get suffix added by low-level

# library

d[key] = data # store data at key (overwrites old data if

# using an existing key)

data = d[key] # retrieve a COPY of data at key (raise KeyError if no

# such key)

del d[key] # delete data stored at key (raises KeyError

# if no such key)

flag = key in d # true if the key exists

klist = list(d.keys()) # a list of all existing keys (slow!)

# or, d=shelve.open(filename,writeback=True) would let you just code

# d['xx'].append(5) and have it work as expected, BUT it would also

# consume more memory and make the d.close() operation slower.

d.close() # close it
