Write the code to produce a for loop that counts down from 20 to 0 by 2’s and prints the number each time it goes through the lo

yulyashka [42]

Explanation:

Count-controlled for loop (Three-expression for loop)

This is by far the most common type. This statement is the one used by C. The header of this kind of for loop consists of a three-parameter loop control expression. Generally it has the form:

for (A; Z; I)

A is the initialisation part, Z determines a termination expression and I is the counting expression, where the loop variable is incremented or dcremented. An example of this kind of loop is the for-loop of the programming language C:

for (i=0; i <= n; i++)

This kind of for loop is not implemented in Python!

Numeric Ranges

This kind of for loop is a simplification of the previous kind. It's a counting or enumerating loop. Starting with a start value and counting up to an end value, like for i = 1 to 100

Python doesn't use this either.

Vectorized for loops

They behave as if all iterations are executed in parallel. This means, for example, that all expressions on the right side of assignment statements get evaluated before the assignments.

Iterator-based for loop

Finally, we come to the one used by Python. This kind of a for loop iterates over an enumeration of a set of items. It is usually characterized by the use of an implicit or explicit iterator. In each iteration step a loop variable is set to a value in a sequence or other data collection. This kind of for loop is known in most Unix and Linux shells and it is the one which is implemented in Python.

Example of a simple for loop in Python:

>>> languages = ["C", "C++", "Perl", "Python"]

>>> for x in languages:

... print(x)

...

C

C++

Perl

Python

Answer:

The answer is D and E

Explanation:

There is no much difference between a port replicator and a docking station. These two terms are used interchangeably and both serve the same purpose of connecting portable computers with other devices with little or no effort. The main difference between the two is that a port replicator provides a solution for all laptops through USB while a docking uses a propriety connector to the computer. Users can use a docking station and a port replicator to convert their laptop PCs into desktop computers when at home or in the office.

Answer:

Cycling, also called bicycling or biking, is the use of bicycles for transport, recreation, exercise or sport.[1] People engaged in cycling are referred to as "cyclists",[2] "bicyclists",[3] or "bikers".[4] Apart from two-wheeled bicycles, "cycling" also includes the riding of unicycles, tricycles, quadricycles, recumbent and similar human-powered vehicles (HPVs).

Cyclists in the 2009 Tro-Bro Léon race.

Police cyclists in London.

A woman cycling in Sri Lanka.

A bike lane in Amsterdam. Bike lanes are dedicated for cyclists and provide shelter from vehicle traffic.

Bicycles were introduced in the 19th century and now number approximately one billion worldwide.[5] They are the principal means of transportation in many parts of the world.

Cycling is widely regarded as an effective and efficient mode of transportation[6][7] optimal for short to moderate distances.

Bicycles provide numerous possible benefits in comparison with motor vehicles, including the sustained physical exercise involved in cycling, easier parking, increased maneuverability, and access to roads, bike paths and rural trails. Cycling also offers a reduced consumption of fossil fuels, less air or noise pollution, reduced greenhouse gas emissions,[8] and greatly reduced traffic congestion.[9] These have a lower financial cost for users as well as for society at large (negligible damage to roads, less road area required). By fitting bicycle racks on the front of buses, transit agencies can significantly increase the areas they can serve.[10]

In addition, cycling provides a variety of health benefits. The World Health Organization (WHO) states that cycling can reduce the risk of cancers, heart disease, and diabetes that are prevalent in sedentary lifestyles.[11][12] Cycling on stationary bikes have also been used as part of rehabilitation for lower limb injuries, particularly after hip surgery.[13] Individuals who cycle regularly have also reported mental health improvements, including less perceived stress and better vitality.[14]

Among the disadvantages of cycling are the requirement of bicycles (excepting tricycles or quadricycles) to be balanced by the rider in order to remain upright, the reduced protection in crashes in comparison to motor vehicles,[15] often longer travel time (except in densely populated areas), vulnerability to weather conditions, difficulty in transporting passengers, and the fact that a basic level of fitness is required for cycling moderate to long distances.
