| I wrote this little python function to reverse speedwalk strings of the form:
4we3(sw)2(up)3e(in)(down)(out)(ne)
It handles e,w,s,n,ne,se,nw,sw,up,down,in and out. It doesn't handle other nonstandard directions. It's not the most efficient code, but it works for me.
import string
def reverseSpeedWalkStr(str):
str=str.lower()
#remove whitespace
strippedstr=''
for eachchar in str:
if eachchar != " ":
strippedstr=strippedstr+eachchar
#add spaces between commands
spacedstr=strippedstr.replace("(sw)","(SW) ")
spacedstr=spacedstr.replace("(se)","(SE) ")
spacedstr=spacedstr.replace("(nw)","(NW) ")
spacedstr=spacedstr.replace("(ne)","(NE) ")
spacedstr=spacedstr.replace("(up)","(UP) ")
spacedstr=spacedstr.replace("(down)","(DOWN) ")
spacedstr=spacedstr.replace("(in)","(OUT) ")
spacedstr=spacedstr.replace("w","W ")
spcadedstr=spacedstr.replace("e","E ")
spacedstr=spacedstr.replace("s","S ")
spacedstr=spacedstr.replace("n","N ")
#reverse order of commands
strlist=spacedstr.split()
strlist.reverse()
reversedstr=string.join(strlist)+' '
#swap direction
swappedstr=reversedstr.replace("(NE) ","(SW)")
swappedstr=swappedstr.replace("(NW) ","(SE)")
swappedstr=swappedstr.replace("(SE) ","(NW)")
swappedstr=swappedstr.replace("(SW) ","(NE)")
swappedstr=swappedstr.replace("(DOWN) ","(UP)")
swappedstr=swappedstr.replace("(UP) ","(DOWN)")
swappedstr=swappedstr.replace("(OUT) ","(IN)")
swappedstr=swappedstr.replace("W ","e")
swappedstr=swappedstr.replace("E ","w")
swappedstr=swappedstr.replace("S ","n")
swappedstr=swappedstr.replace("N ","s")
swappedstr=swappedstr.lower()
return(swappedstr)
