python 多行字符串

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'
