Errata

• Page 49: Bullet point no. 7 must be read as "Initialize the for loop from offer to highest: while offer <= highest:"
• Page 76: The output for aretha should be ('aretha', 75)
• Page 478: Bullet point no. 1 must read "Head to the notebook file that you used for exercises 148-153 and run all the cells in the notebook so that all the variables are stored." instead of "Head to the notebook file that you used for exercises 147-151 and run all the cells in the notebook so that all the variables are stored."
• Page 525: Figure caption for Figure 12.37 must be read as "An output for Activity 27 with 91% accuracy" instead of "Figure 12.37 – An output for Activity 26 with 91% accuracy"

Instructions and Navigations

All of the code is organized into folders. For example, Chapter02.

The code will look like the following:

s1 = set([1,2,3,4,5,6])
print(s1)
s2 = {1,2,2,3,4,4,5,6,6}
print(s2)
s3 = {3,4,5,6,6,6,1,1,2}
print(s3)

Following is what you need for this book: This book is for professionals, students, and hobbyists who want to learn Python and apply it to solve challenging real-world problems. Although this is a beginner’s course, you’ll learn more easily if you already have an understanding of standard programming topics like variables, if-else statements, and functions. Experience with another object-oriented program, though not essential, will also be beneficial. If Python is your first attempt at computer programming, this book will help you understand the basics with adequate detail for a motivated student.

With the following software and hardware list you can run all code files present in the book (Chapter 1-13).

Software and Hardware List

Chapter	Software required	OS required
1-13	Python 3.11	Windows, macOS, or Linux
1-13	Jupyter notebook	Windows, macOS, or Linux

Graham Lee is an experienced programmer and writer. He has written several books, including Professional Cocoa Application Security, Test-Driven iOS Development, APPropriate Behaviour, and APPosite Concerns. He is a developer who's been programming for long enough to want to start telling other people about the mistakes he's made in the hope that they'll avoid repeating them. In his case, this means having worked for about 12 years as a professional. His first programming experience can hardly be called professional at all, as it was in BASIC on a Dragon 32 microcomputer.

the-python-workshop-second-edition's Issues

Typo on page 8

On page 8 it says "Trying to follow certain conventions is it's acceptable." I think you might be trying to say "Try to follow certain conventions." or "Trying to follow certain conventions is acceptable"

Typo in output at bottom of page 76

At the bottom of page 76 the output for aretha should be ('aretha', 75)

exercise 33 does not match book

On page 81 of the book the exercise has you create sets in different ways but in the file in this repo all the sets are created the same way

exercise 53 uses a global variable without explanation

The global variable in used in exercise 53 but it is never introduced to the reader. A check of the index implies that it will never be explained.

Figure 1.16 Wrong

Figure 1.16 on page 36 is wrong.

Page 115 references Fibonacci for the first time

On page 115 Activity 10 says the 'recall that each term in the Fibonacci sequence....' But this is the first time it was mentioned.

page 46 needs correction

Page 46 says that this is the first time we're using double indentation, but we used it on page 41 in exercise 16.

errata for page 49 wrong

Your errata reads: "Page 49: Bullet point no. 7 must be read as "Initialize the for loop from offer to highest: while offer <= highest:"" but it's not a for loop at all - it's a while loop.

chapter 1 exercise 18 does not match file

On page 47 and 48 the exercise steps for exercise 18 do not match the file at all and do not work.

minor: sum_to_10 never introduced

On page 97 there is a line of code that says 'from sum_to_10 import result' but no where before that was it explained that the code above that was sum_to_10.

exercise 53 uses formatting expressions without introduction

Exercise 53 uses the string formatting expression without ever introducing it to the reader, I had to go find the answer elsewhere to what I was looking at. A new concept shouldn't be used in an exercise without introduction or at least providing a link to more info

Activity 9

Activity 9, as far as I am aware, introduces % strings for the first time which is confusing. Please explain before.

missing quotes on exercise 33 page 81

At the bottom of page 81 on step 3 of exercise 33 there are missing single quotes after "graham" and "ailey"

activity 4 on page 46 doesn't match answer

Activity 4 on page 46 says to use the f-string to output the results, but the answer in the appendix doesn't do that.

Exercises numbered from from chapter 3

Chapter 2 has the last exercise of 34 and then in the chapter 3 folder here in the repo it starts with exercise 34 even though it's really the content from exercise 35
