replacing strings in files from list in python
Question: So I need to find all files with certain extension in this case `.txt`. Then I
must open all these files and change certain string with another string... and
here i'm stuck.

here is my code:

    
    
    import os, os.path
    
    find_files=[]
    
    for root, dirs, files in os.walk("C:\\Users\\Kevin\\Desktop\\python programi"):
    for f in files:
        fullpath = os.path.join(root, f)
        if os.path.splitext(fullpath)[1] == '.txt':
            find_files.append(fullpath)
    for i in find_files:
        file = open(i,'r+')
        contents = file.write()
        replaced_contents = contents.replace('xy', 'djla')
        print i
    

ERROR mesage:

    
    
    line 12, in <module>
        contents = file.write()
    TypeError: function takes exactly 1 argument (0 given)
    

i know that there is misssing an argument but which argument should I use? i
think it would be better if i change the code from `for i in find files:` down
any advice?


Answer: I think you mean to use `file.read()` rather than `file.write()`
