笨方法学python 习题32

the_count = [1, 2, 3, 4, 5]
fruits = ['apples', 'oranges', 'pears', 'apricots']
change = [1, 'pennies', 2, 'dimes', 3, 'quarters']

# this first kind of for-loop goes through a list
for number in the_count:
    print ("This is count %d" % number)

# same as above
for fruit in fruits:
    print ("A fruit of type: %s" % fruit)

# also we can go through mixed lists too  我们也可以通过混合列表
# notice we have to use %r since we don't know what's in it for i in change:  注意我们必须使用% r,因为我们不知道的我在改变
for i in change:
    print ("I got %r" % i)

# we can also build lists, first start with an empty one  我们也可以构建列表,先挖空
elements = []

# then use the range function to do 0 to 5 counts  然后使用范围0到5项功能
for i in range(0, 6):
    print ("Adding %d to the list." % i)

# append is a function that lists understand elements.append(i)  附加是一个函数列表理解elements.append(i)
    elements.append(i)

# now we can print them out too
for i in elements:
    print ("Element was: %d" % i)
