Python terminfo参数化字符串中的延迟

在terminfo的手册页中，提到了在编码中指定延迟的

$

，在

ms

中，其角括号内是精度最多为小数点后一位的a数字

通过以下python脚本，我确认

$的语法非常明确：

   A  delay  in  milliseconds  may appear anywhere in a string capability,
   enclosed in $<..> brackets, as in el=\EK$<5>,  and  padding  characters
   are supplied by tputs(3x) to provide this delay.

   o   The delay must be a number with at most one decimal place of preci-
       sion; it may be followed by suffixes "*" or "/" or both.

   o   A "*" indicates that the padding required is  proportional  to  the
       number  of lines affected by the operation, and the amount given is
       the per-affected-unit padding required.  (In  the  case  of  insert
       character, the factor is still the number of lines affected.)

       Normally, padding is advisory if the device has the xon capability;
       it is used for cost computation but does not trigger delays.

   o   A "/" suffix indicates that the padding is mandatory and  forces  a
       delay of the given number of milliseconds even on devices for which
       xon is present to indicate flow control.

以毫秒为单位的延迟可能出现在字符串功能中的任何位置，
用$括号括起来，如el=\EK$和填充字符
由TPUT（3x）提供，以提供此延迟。
o延迟必须是一个最多小数点后一位的数字-
锡安；它可以后跟后缀“*”或“/”或两者。
o A“*”表示所需的填充与
受操作影响的行数，给出的数量为
需要每个受影响单元的填充。（在插入的情况下）
字符，该因子仍然是受影响的行数。）
通常，如果设备具有xon功能，则填充是建议性的；
它用于成本计算，但不会触发延迟。
o后缀“/”表示填充是必需的，并强制
给定毫秒数的延迟，即使在
xon表示流量控制。

如果没有结尾，则语法非常明确：
