【Python基础教程第2版】——第一讲:基础知识

1、长字符串:(用三引号如'''或者"""来引起来)

>>> print """
This is a very log string.
It continues here.
And it's not over yet.
"Hello world!"
"""

This is a very log string.
It continues here.
And it's not over yet.
"Hello world!"

2、原始字符串:(注:最后面不要出现转义符,其他的都会保持原样显示,中间不用使用转义符)

>>> print r'C: owhere'
C: owhere

3、字符串表示:str和repr

(str函数:会把值转换为合理形式的字符串;repr函数:会创建一个字符换,以合法的Python表达式的形式来表示值)

>>> print str(temp)
42
>>> print '1238934'+str(temp)
123893442

>>> print 'the temp is '+ repr(temp)
the temp is 42
