運行上述代碼我得到輸出作爲

NNN NNN找到匹配

DDD ---未發現原材

嗯----找不到原材

bbb_13 bbb_12不匹配或版本變化

可以請任何人都可以引導我

f1 = open("C:\\Python34\\master_test.csv", "r") 
f2 = open("C:\\Python34\\child_test1.csv", "r") 
outFile = open("C:\\Python34\\output.csv", "w") 

fileOne = f1.readlines() 
fileTwo = f2.readlines() 

f1.close() 
f2.close() 
for i in fileOne: 
    for x in fileTwo: 
     if (x == i): 
      outFile.write(i +"Equal " + x)

你可以做這樣的事情

f1 = open("C:\\Python34\\master_test.csv", "r") 
    f2 = open("C:\\Python34\\child_test1.csv", "r") 
    outFile = open("C:\\Python34\\output.csv", "w") 

    fileOne = f1.readlines() 
    fileTwo = f2.readlines() 

    f1.close() 
    f2.close() 
    for i in fileOne: 
     for x in fileTwo: 
      writer = "{} --- Not found Master sheet".format(i) 
      if (x == i): 
       writer = "{} {} match found".format(i,x) 
      outFile.write(writer+'\n') 

This will keep the message in writer always that BlahBlahBlah! not found un master, But in case it is found then the writer will change to Blah Blah match found 


Hello 
thank you for your reply, 
But above code is not solved my issue, 



f1 = open("C:\\Python34\\master_test.csv", "r") 
f2 = open("C:\\Python34\\child_test1.csv", "r") 
outFile = open("C:\\Python34\\Aoutput.csv", "w") 

fileOne = f1.readlines() 
fileTwo = f2.readlines() 

f1.close() 
f2.close() 
outFile.write("Match found\n") 
for i in fileOne: 
    for x in fileTwo: 

     if (x == i): 
     output.write(x)#Match found 

output.write("Match not found") 
#similar way if check 
for i in fileOne: 
    for x in fileTwo: 
     if (x != i): 
     output.write(x) 
#Its writing all the combination, I need only not match from child values i.e 

DDD

嗯
