python中有两种循环,for循环和while循环。for 循环用于重复某件事 n 次。while循环用于重复直到发生某些事情。For-loops 对于游戏编程很有用,因为它们经常处理游戏显示的帧。每一帧通过一个循环运行一次。存储 for 循环的方式是使用列表。这是您可以熟悉的基本循环的示例:
he_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
# notice we have to use %r since we don't know what's in it
for i in change:
print "I got %r" % i
# we can also build lists, first start with an empty one
elements = []
# then use the range function to do 0 to 5 counts
for i in range(0, 6):
print "Adding %d to the list." % i
# append is a function that lists understand
elements.append(i)
# now we can print them out too
for i in elements:
print "Element was: %d" % i
