Bug report

Bug description:

I use Python downloaded from python.org without using a graphical environment such as IPython. Instead, I use the Windows Terminal with the REPL built into python.exe. In 3.12.6, I can paste a function definition copied from a text editor directly into the REPL and everything works fine. In 3.13.rc2 this does not work; the indentation is all messed up and I get an IndentationError.

defletter_colors(word,guess):'''Compute letter colors for Wordle guesses.  B=black Y=yellow G=green'''if (n:=len(word))!=len(guess):raiseValueError('Word and guess must be the same length.')result= ['G'ifwl==glelse'B'for (wl,gl)inzip(word,guess)]unused= [wfor (w,r)inzip(word,result)ifr=='B']fori,cinenumerate(guess):ifresult[i]!='G'andcinunused:result[i]='Y'unused.remove(c)return''.join(result)
