Python3 compatible memo of "python start book"

The "python Startbook" is a highly recommended book for programming beginners to learn python while learning the concept of programming. However, since this book is a little old (2010) and only supports python2, I have summarized the confusion when studying python3 using this book.

Overall. On paper, at the beginning of the script # coding:utf-8 However, in python3, the character code is utf-8 by default, so it is unnecessary.

BMI calculation and so on. raw_input () is not in python3. → Use input ()

Create your own module, import it, and reload it. Reload () function is obsolete in python3

import importlib
importlib.reload(my_module)

Where to use the map () function. When it looks like map (str, [1,2,3]), the result is different from the one on paper.

→ In python2, it is automatically returned as a list format, but in python3, it is not returned. You need to enclose it in list ().

list(map(str, [1,2,3]))
