Answer:
Explanation:
Use composition when you can, private inheritance when you have to. Normally you don't want to have access to the internals of too many other classes, and private inheritance gives you some of this extra power
Answer:
A BitTorrent software consumer utilizes that data into the torrent data to communicate special tracker and support shifting of that data among networks including either complete or incomplete representations about the data-set.
Explanation:
BitTorrent is based at the thought of any torrent, which is a smallish data that includes metadata regarding a host, specific tracker, that organizes the data sharing and data that is distributed. A peer that wants to advance data available need first attain a tracker for the data, generate a torrent and later share the torrent data. Different peers can next use the information included in the torrent file support all other in downloading that data. That download is organized by that tracker.
Answer:
The statement is as follows:
print("{0:,.1f}".format(number))
Explanation:
Required
Statement to print 1234567.456 as 1,234,567.5
To do this, we make use of the format keyword, and we set the print format in the process.
To round up number to 1 decimal place, we use the following format:
"{0:,.1f}"
To include comma in the thousand place, we simply include a comma sign before the number of decimal place of the output; i.e. before 1
"{0:,.1f}"
So, the print statement is:
print("{0:,.1f}".format(number))
Answer:
def barGraph(w, h, data):
# creating Canvas
paper = Canvas(w, h)
# defining variables
largest = max(data) # largest element in data
length = len(data) # length of data list
barWidth = 0.8 * w / length # length of each bar of the histogram
maxBarHeight = 0.8 * h # maximum height of each bar of the histogram
minBarHeight = maxBarHeight / largest # minimum height of each bar
# Starting points
x = 0.1 * w
y = 0.9 * h
# looping through the list
for i in data:
currBarHeight = minBarHeight * i # current bar height
x1 = x + barWidth
y1 = y - currBarHeight
# creating the rectangle, and adding it to the bar graph
bar = Polygon( Point(x,y), Point(x,y1), Point(x1,y1), Point(x1,y) )
bar.setFillColor('grey')
paper.add(bar)
x = x1
# returning the canvas
return paper
