字符串是要用引号(双引号,单引号,多行用三个引号)引起来
TypeError: not enough arguments for format string
you have to specify multiple arguments as tuple, eg
print "%d %s of beer on the wall," % (bottles, s1)
去空格及特殊符号
s.strip().lstrip().rstrip(‘,‘)
连接字符串
sStr1 = ‘strcat‘ sStr2 = ‘append‘ sStr1 += sStr2 print sStr1
>>> s = ‘s‘ >>> s2 = ‘s2 %s‘ % s >>> s2 ‘s2 s‘
