字從文本文件替換到另一個一行一行在Python

Question

輸入文件：

0A

1B

2C

3D

我有一個文本文件這些行下面

1. -c0 -k2 -w1 -x1.0 -y1.0 -ia8.ac3 -opdut_decoded.wav，opdut_decoded.wav，opdut_decoded.wav
2. -c0 -k2 -w1 -x1.0 -y1.0 -ia9.ac3 -opdut_decoded.wav，opdut_decoded.wav，opdut_decoded.wav
3. -c0 -k2 -w1 -x1.0 -y1.0 -ia18.ac3 -opdut_decoded.wav
4. -c0 -k2 -w1 -x1.0 -y1.0 -iLFE1.ac3 -opdut_decoded.wav

我想通過 「-opdut_decoded.wav」 中的每一行，以取代上述給定的輸入線這樣

1. -c0 -k2 -w1 -x1.0 -y1.0 -ia8.ac3 -0a.ac3,0a.ac3,0a.ac3
2. -c0 -k2 -w1 -x1.0 -y1.0 - ia9.ac3 -1b.ac3,1b.ac3,1b.ac3
3. -c0 -k2 -w1 -x1.0 -y1.0 -ia18.ac3 -2c.ac3
4. -c0 -k2 -w1 - X1.0 -y1.0 -iLFE1.ac3 -3d.ac3

Answer 1

this is how I would construct the list with your input file 
import re  
    rep_file = open('in2','r') 
    new_words = [] 
    for line in rep_file: 
     line = line.strip() 
     new_words.append(line + '.ec3') 

    infile = open('in.txt','r')  
    data = infile.read()  
    matches = re.findall(r'(opdut_decoded\.wav)',data)  
    i = 0  
    for m in matches: 

     data = re.sub(m,new_words[i],data,1) 
     i += 1 

    out = open('out.txt','w') 
    out.write(data)  
    out.close() 

Answer 2

試試這個，

f = open('info.txt', 'r+') 
filedata = f.read().replace("opdut_decoded.wav", "a88.wav") 
f.write(filedata) 
f.close() 

希望這將工作

Answer 3

import re  
    new_words = ['0a.ec3' , '1b.ec3' ,'2c.ec3' ,'3d.ec3' , '4e.ec3' , '5f.ec3' , '6e.ec3']  
    infile = open('in.txt','r')  
    data = infile.read()  
    matches = re.findall(r'(opdut_decoded\.wav)',data)  
    i = 0  
    for m in matches: 

     data = re.sub(m,new_words[i],data,1) 
     i += 1 

out = open('out.txt','w') 
out.write(data)  
out.close()
