This module is one in a collection of modules on Python designed for teaching ITSE 1359 Introduction to Scripting Languages: Python at Austin Community College in Austin, TX.
This module contains review questions and answers keyed to the module titled Itse1359-1050-Introduction to Scripts .
Once you study that module, you should be able to answer the review questions in this module.
The questions and the answers in this module are connected by hyperlinks to make it easy for you to navigate from the question to the answer and back again.
(Note to blind and visually impaired students: with the exception of two bitmap images that are used solely as spacers to separate the question sectionfrom the answer section, all of the material in this module is presented in plain text format and should be accessible using an audio screen reader or abraille display.)
In your own words, what is a script?
Go to answer 1
True or False? A script can be used only once and must then be discarded.
Go to answer 2
Convert the interactive program shown in Figure 1 into a script, execute it, and confirm that you get the correct result.
In case you didn't get any output, note that unlike in interactive mode, in order to cause a script to produce an output, you will need to use a statementsomething like the following:
print(x+y)
| Figure 1 . Question 3. |
|---|
>>>x=6 # create and populate x>>>y=5 # create and populate y>>>x+y # add x to y and display the sum
11>>> |
Go to answer 3
Convert the interactive program shown in Figure 3 into a script and execute it.
| Figure 3 . Question 4. |
|---|
>>>a=b=c=10 # assign 10 to several variables>>>a+b+c # add them together
30>>>a=b=c=20 # assign 20 to same variables>>>a+b+c # add them together
60>>> |
Go to answer 4
Convert the interactive program shown in Figure 5 into a script and execute it.
| Figure 5 . Question 5. |
|---|
>>>x=5>>>y=6>>>x+y
11>>>x=5.55555>>>y=6.66666>>>x+y
12.22221>>> |
Go to answer 5
Convert the interactive program shown in Figure 7 into a script and execute it.
| Figure 7 . Question 6. |
|---|
>>>5+6
11>>>_+22 # add 22 to the continuation variable
33>>> |
Go to answer 6
Convert the interactive program shown in Figure 9 into a script and execute it.
| Figure 9 . Question 7. |
|---|
>>>print("Dick\nBaldwin")
DickBaldwin>>> |
Go to answer 7
What is the meaning of the following two images?
These images were inserted here simply to insert some space between the questions and the answers to keep them from being visible on the screen at thesame time.
This image was also inserted for the purpose of inserting space between the questions and the answers.
One possible solution is provided in Figure 10 .
| Figure 10 . Answer 7. |
|---|
print("Dick\nBaldwin") |
Go back to Question 7
One possible solution is provided in Figure 8 .
| Figure 8 . Answer 6. |
|---|
x = 5+6
print(x)x = x + 22
print(x) |
If you were unable to get this to work, don't be dismayed. The special variable whose name is the underscore character is available only ininteractive mode. Therefore, you can't use that variable in a script, and you will need to develop a workaround.
Go back to Question 6
One possible solution is provided in Figure 6 .
| Figure 6 . Answer 5 |
|---|
x=5
y=6print(x+y)
x=5.55555y=6.66666
print(x+y) |
Go back to Question 5
One possible solution is provided in Figure 4 .
| Figure 4 . Answer 4. |
|---|
a=b=c=10 # assign 10 to several variables
print(a+b+c) # add them togethera=b=c=20 # assign 20 to same variables
print(a+b+c) # add them together |
Go back to Question 4
One possible solution is provided in Figure 2 .
| Figure 2 . Answer 3. |
|---|
x=6 # create and populate x
y=5 # create and populate yprint(x+y) # add x to y and display the sum |
Go back to Question 3
False. Script files are reusable.
Go back to Question 2
A script is a text file containing the programming statements that comprise a Python program.
Go back to Question 1
This section contains a variety of miscellaneous information.
Financial : Although the Connexions site makes it possible for you to download aPDF file for this module at no charge, and also makes it possible for you to purchase a pre-printed version of the PDF file, youshould be aware that some of the HTML elements in this module may not translate well into PDF.
I also want you to know that, I receive no financial compensation from the Connexions website even if you purchase the PDF version ofthe module.
In the past, unknown individuals have copied my modules from cnx.org, converted them to Kindle books, and placed them for sale onAmazon.com showing me as the author. I neither receive compensation for those sales nor do I know who does receive compensation. If youpurchase such a book, please be aware that it is a copy of a module that is freely available on cnx.org and that it was made andpublished without my prior knowledge.
