python-3.x - clearTxt：TypeError：需要一个类似字节的对象，而不是“dict”

Question

def clearTxt(line):
if line != '': 
    line = line.strip()
    intab = ""
    outtab = ""
    trantab = str.maketrans(intab, outtab)
    #trantab = json.dumps(trantab).encode('utf-8')
    pun_num = string.punctuation + string.digits
    #pun_num = json.dumps(pun_num).encode('utf-8')
    line = line.encode('utf-8')
    #line = json.dumps(line).encode('utf-8')
    line = line.translate(trantab,pun_num)
    line = line.decode("utf-8")

location:line = line.translate(trantab,pun_num)。在我看来，它与“trantab”或“pun_num”的类型有关。“#”是我尝试过的。它们不起作用。所以。 .. 先感谢您
