Question

我的python脚本正在使用下面的代码，但是tkinter不能逐行打印，我怀疑函数内部的函数不起作用

工作脚本：

def writeline(line):
    down.write(line + "\n")

ip="**.**.**.**"

ftp = FTP(ip)  
ftp.login('','')

print ("PLEASE ENTER THE PROGRAM NAME TO BE EXECUTED :")
file = input()

try:
    down = open(file, "w")
    print(ftp.voidcmd( "site file=jes" ))
    print(ftp.voidcmd( "site sbd=(IBM-273,ISO8859-1)"))
    ftp.retrlines("retr " + file, writeline)
    down.close()
except:
    print("Unable to Download file")

Tkinter代码（不起作用）：

def writeline(line):
    down.write(line + "\n")

def downloadFile():
    file = ent_input.get()    
    try:
        down = open(file, "w")
        writeline()
        ftp.voidcmd("site file=jes")
        ftp.voidcmd("site sbd=(IBM-273,ISO8859-1)")
        text_servermsg.insert(END,"Downloading " + file + " ...")
        text_servermsg.insert(END,ftp.retrlines("retr " + file ,writeline))
    except:
        text_servermsg.insert(END,"\n")
        text_servermsg.insert(END,"Unable to Download file")
