Now the person who wrote the book is a bit of a sense of responsibility, recently read a few books, where the code is wrong.

Recently obsessed with Python games, bought "Getting started with Python game programming" [US] Jonathan S. Harbour a book to see.

In the fourth chapter: Bomb catcher game, the program code to test typing speed is seriously wrong.

Change the program screen randomly display a letter, the key to enter the letter randomly displayed next, calculate the average one minute can enter how many letters, the original code in the calculation of the speed of a piece of error, with my revised code
