本文详细解释了在Python控制台中使用''和' '的区别，帮助开发者理解这两种特殊字符的输出效果，并提供实际应用场景的对比。

不明白为什么以下语句：

while True:
for i in ["/","-","|","\\","|"]:
print "%s\b" % i,

跟

while True:
for i in ["/","-","|","\\","|"]:
print "%s\r" % i,

的输出显示跟自己预期相反。

根据下表，

Escape	What it does.
\\	Backslash ()
\'	Single-quote (')
\"	Double-quote (")
\a	ASCII bell (BEL)
\b	ASCII backspace (BS)
\f	ASCII formfeed (FF)
\n	ASCII linefeed (LF)
\N{name}	Character named name in the Unicode database (Unicode only)
\r ASCII	Carriage Return (CR)
\t ASCII	Horizontal Tab (TAB)
\uxxxx	Character with 16-bit hex value xxxx (Unicode only)
\Uxxxxxxxx	Character with 32-bit hex value xxxxxxxx (Unicode only)
