如何替换 Python 字符串中的所有字符？

Question

I found a solution on stackoverflow but it doesn't seem to work. I have made a string scanner that checks for character frequency and then replaces all characters with the "real" characters. I've made sure that the character recognition works but when I try replacing all characters in a string they no longer match up with the expected/calculated characters (when I try replacing for example only 2 characters it works fine and matches up perfectly). Here is my replacement code:

print(text.replace(re,'e').replace(rt,'t').replace(ra,'a').replace(ro,'o').replace(ri,'i').replace(rn,'n').replace(rs,'s').replace(rr,'r').replace(rh,'h').replace(rl,'l').replace(ru,'u').replace(rc,'c').replace(rm,'m').replace(rf,'f').replace(ry,'y').replace(rw,'w').replace(rg,'g').replace(rp,'p').replace(rb,'b').replace(rv,'v').replace(rk,'k').replace(rx,'x').replace(rq,'q').replace(rj,'j').replace(rz,'z').replace(rd,'d'))

You might want to take a look at translate . Your code would probably look something like

text = text.translate(str.maketrans('abcd...', ''.join([ra, rb, rc, rd...]))
