如何更新歷史並將結果寫入其他文本文件？

我需要更新history_ends = 5000
我需要編寫所有的print語句到一個文本文件

我需要這樣做，直到文件中的行結束爲止

history_begins = 1; history_ends = 5000; n = 0; total = 0 
historyjobs = []; targetjobs = [] 
listsub = []; listrun = []; listavg = [];listfinal = [] 

def check(inputfile): 
    f = open(inputfile,'r') 
    lines = f.readlines() 
    for line in lines: 
    job = line.split() 
    if(int(job[0]) < history_ends): 
     historyjobs.append(job) 
    else: 
     targetjobs.append(job) 
    print len(historyjobs) 
    print len(targetjobs) 
    print targetjobs[0] 
    j = 0   
    for i in range(len(historyjobs)): 
    if((int(historyjobs[i][3]) == int(targetjobs[j][3])) and (int(historyjobs[i][4]) == int(targetjobs[j][4])) and (int(historyjobs[i][5]) == int(targetjobs[j][5]))): #i am comparing 3rd,4th & 5th columns of list historyjobs and targetjobs 

     listsub.append(historyjobs[i][1]) #storing the column num 1 to listsub 

     listrun.append(historyjobs[i][2]) #storing the column num 1 to listrun 

    print listsub 
    print len(listsub)     
    print listrun 

def runningMean(seq, n=0, total=0): 
    if not seq: 
    return [] 
    total =total+int(seq[-1]) 
    return runningMean(seq[:-1], n=n+1, total=total) + [total/float(n+1)] 

def main(): 
check('newfileinput') 
listavg = runningMean(listsub,n = 0,total = 0) 
print listavg 
for i in range(len(listsub)): 
    if (int(listsub[i]) > float(listavg[i] * 0.9)): 
     listfinal.append(listsub[i]) 
print listfinal 

if __name__ == '__main__': 
     main()

代碼的輸出是：

現在我需要的輸出中顯示的結果爲5001,5002,5003 ..............直到結束&的輸出（打印語句）寫在另一個文本文件中。代碼中的哪些變化將爲我提供結果。Plz可以提供任何一種python解決方案

實際上並不清楚你想做什麼編號爲1和3的列表）

要重定向所有打印輸出，您可以這樣做：

import sys 
f = open('log.txt', 'w') 
sys.stdout = f 
print "test"

之後，您可以設置返回設置標準輸出到原來的狀態：sys.stdout = sys.__stdout__
