Python入門（五）流程控制、循環簡介

for循環：在python for 循環遍歷序列，如一個列表或者字符

#coding:utf8
infoList = ['nan','shuai','qian']
for x in infoList:
	if x == 'shuai':
		print 'with first'
	elif x == 'qian':
		print 'with second'
	elif x == 'nan':
		print 'with ugly'
	else:
		print 'go out'

打印九九乘法表

#coding:utf8

for x in range(1,10):
	for y in xrange(1,10):
		print x,y, x*y

循環控制：
break, 結束循環
continue, 跳過本次循環後繼續
pass. 佔位，代碼樁

for i in range(10):
	if i == 2:continue
	if i == 10: break
	if i == 4: pass
	print i
