Explanation:
The following is written in Python. It creates the dictionary as requested and prints it out to the output file as requested using the correct format for various shows with the same number of seasons.The output can be seen in the attached picture below.
mydict = {}
with open("file1.txt", "r") as showFile:
for line in showFile:
cleanString = line.strip()
seasons = 0
try:
seasons = int(cleanString)
print(type(seasons))
except:
pass
if seasons != 0:
showName = showFile.readline()
if seasons in mydict:
mydict[seasons].append(showName.strip())
else:
mydict[seasons] = [showName.strip()]
f = open("output.txt", "a")
finalString = ''
for seasons in mydict:
finalString += str(seasons) + ": "
for show in mydict[seasons]:
finalString += show + '; '
f.write(finalString[:-2] + '\n')
finalString = ''
f.close()
<u>Windowing</u> is the detection of events that fall inside a specified set of parameters, such as within or outside of a specified time frame.
<h3>What is windowing?</h3>
Windowing is the process of processing and analysing a small subset of a bigger dataset. The rectangular window is a crude method that merely truncates the dataset before and after the window without altering the contents of the window in any way.
A windowing system allows many apps to simultaneously share a computer's graphical display presentation resources. You might want to utilise several programmes simultaneously on a computer with a graphical user interface (GUI) (this is called task).
Therefore, windowing is detection of events within a given set of parameters, such as within a given time period or outside a given time period.
