我正在研究Python, 并且一直在实验逃生序列 < code> v 和 < code> f 。 输出似乎给我放这2个逃生序列的地方提供了奇怪的符号。 由于网站的一些垃圾邮件预防政策, 我无法张贴输出的图像 。 有人能给出问题所在的想法吗? 谢谢 。
Escape-sequences are documented here:
http://docs.python.org/reference/lexical_analysis.html#string-literals
v is a vertical tab
f is a form feed
If you print them in the REPL you get the hexadecimal value (0c).
Example:
>>> f
x0c
As with some other conventions, the x escape-sequence is inherited from C.
Reference: http://www.python.org/dev/peps/pep-0223/
Aside:
If you prefer the ASCII code to the hex code you can use ord():
>>> ord( f )
12
