Correct answer

This book will guide you on how to use it appropriately when conducting classes or studying on your own.

● The process of writing code by hand and inferring the output value is commonly called hand coding.
The problems in the Text Coding Workbook are structured so that they can be easily solved by hand coding.
Try solving the problem by following the code step by step using the hand-coding method.
It's good to solve it quickly, but it's more important to solve it accurately without making any mistakes.

● Type the problem code directly into Python idle or an online IDE (such as ideone) and check the output.
Just following along can be a significant learning experience.
If the code doesn't run even though you followed it exactly, try to find the cause.
In the process, you can have fun solving problems and develop your skills.

Author's Note

I still vividly remember the students struggling when I first taught them text coding.
The reasons why students struggled were varied.
From students who struggle with English typing, to students who get frustrated because they can't find the small spelling differences between input and lnput, to students who can't understand why print(1+2) and print("1"+"2") don't both result in 3.
The problem is that students who experience these difficulties are not a minority, so teachers often encounter unexpected challenges.
In fact, this problem is a hurdle that everyone, regardless of age or gender, must overcome when learning a text-based language.
In other words, it is neither the learner's fault nor the teacher's fault.
However, research and consideration were needed to make teaching text language more efficient and easier to learn.
This textbook contains the thoughts of 10 information teachers who tried to make such difficulties a little easier.
In text coding, grammar is ultimately about understanding the structure, or framework.
Although the detailed grammar may differ slightly from language to language, the overall framework, from input/output to conditional structures, is mostly similar.
Therefore, if you understand the overall structure first rather than delving deep into grammar, you can approach text coding much more easily.
I hope that through this book, you will build a foundation in grammar and develop an eye for the overall framework of text code.
