数字前面的\表示输入的是10进制ascii值
'\e'就是两个字符,但是因为'\'有特别含义所以用'\\'表示'\'
'\t'是转义字符.

Pyhton 里 \f 表示 ASCII Formfeed 字符, 也就是进纸指令,该指令的 ASCII 码为 12 , 换算成16进制就是 0c
\f ASCII Formfeed (FF)

请问，“Pyhton 里 \f 表示 ASCII Formfeed 字符”
你是从哪里学到的？

你在索引里找escape sequence，
2.4.1 String literals中就有说:

Unless an "r" or "R" prefix is present, escape sequences in strings are
interpreted according to rules similar to those used by Standard C. The
recognized escape sequences are:

  Escape Sequence Meaning Notes  \newline Ignored  \\ 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)
(1) \Uxxxxxxxx Character with 32-bit hex value xxxxxxxx (Unicode only) (2)
\v ASCII Vertical Tab (VT)  \ooo Character with octal value ooo (3,5)
\xhh Character
with hex value hh (4,5)
