用Notepad++打下列的程式碼,
另存為Chapter_2.py. 我附上中文注釋方便好讀.

# Automate The Boring Stuff With Python - Chapter 2

# 導入一個random模組
import random

# 練習布爾運算: 注意順序:算術 > 大小 > not > and > or
print(2 + 2 == 2 * 2 and not True or False and 2 + 3 < 3 + 2 or True)

print ('#' * 10)
# 練習while用法, 及輸入input
Name = ''
while Name != 'AI':
    print ('Who are you?')
    Name = input('Typing "AI": ')

print ('#' * 10)
# 練習 for in range, print寫法注意
for i in range (0, 5, 2):
   print('The Number (' + str(i) + ')')

print ('#' * 10)
# 練習while用法
i = 1
while i <= 10:
    print (i)
    i = i + 1

print ('#' * 10)
# 產生0-2亂數, 當亂數為1 , 2 或其他數時, 印出不同的字
spam = random.randint(0, 3)
print('spam =', spam)
if spam == 1:
    print('Hello')
elif spam == 2:
    print('Howdy')
else:
    print('Greetings!')

然後用Windows的cmd, 執行python.
