python程序产生相同的输出不输入

Question

我有一个python程序，它每分钟读取一个二进制文件，包含实时股票市场数据，接受它们的名称作为命令行参数，并将它们的内容写入数据库表。但是，它似乎为每个文件生成相同的输出，而不管其内容是什么，因为每个文件都有不同的值。我能做些什么摆脱这个问题？

谢谢和问候。继承我的代码：

import struct as st
import pymysql
import sys
import os

os.chdir(r'/root/IND')
print("FILE TO BE OPENED:",sys.argv[1]+".ind")
fName=sys.argv[1]+".ind"
print("you want to open",fName)

mkt = open(fName, "rb")
print("Opened",fName)

transcode=5
mlength=78
i=0

while(i<46):
 #HEADER DATA

 transcode = int.from_bytes(mkt.read(2), byteorder='little')

 timestamp = int.from_bytes(mkt.read(4), byteorder='little')

 mlength = int.from_bytes(mkt.read(2), byteorder='little')

#BODY DATA

 indtok = str(int.from_bytes(mkt.read(2), byteorder='little'))
 print("Token:                                                                ------------------------",indtok)

 iov = int.from_bytes(mkt.read(4), byteorder='little')

 civ = str(int.from_bytes(mkt.read(4), byteorder='little'))
 print("Value:",civ)

 hiv = int.from_bytes(mkt.read(4), byteorder='little')

 liv = int.from_bytes(mkt.read(4), byteorder='little')

 pc = str(int.from_bytes(mkt.read(4), byteorder='little'))
 print("Percentage change:",pc)

 ihiv = int.from_bytes(mkt.read(4), byteorder='little')

 iliv = int.from_bytes(mkt.read(4), byteorder='little')

 ioiv = int.from_bytes(mkt.read(4), byteorder='little')

 iciv = int.from_bytes(mkt.read(4), byteorder='little')

 filler = int.from_bytes(mkt.read(4), byteorder='little')

 #print(i,"--NEXT FILE")
 i+=1
