I get an FileNotFouerror while try to open(file,"rt"). My goal is to replace str

[decoded]

I have a folder with .txt files. In that folder I want to list all the files and read each files and replace a specific String. The problem I get is that the error message is telling me there is no such file or directory which are strange since I can list the files with a print. The "test2.txt" that are listed in my error message is just one of the files in that specific folder.


This is my code:

import os

#declare my folder
ws_folder =r"C:\FMEData\test"

#declare what to replace
search_text = "FMEData2019"
replace_text = "FMEData"

#list files in directory
listdir=os.listdir(ws_folder)
#printing files in directory for check
print (listdir)

for file in listdir:
    #checking if i can print the files
    print(file)
    
    #Open each file as read mode
    openfile= open(file,"rt")
    
    #read each opened file
    data=openfile.read()
    
    #replace text for each opened file
    data = data.replace('search_text', 'replace_text')
    #close the file
    openfile.close()
    
    #the open file as write mode
    openfile = open("file", "wt")
    openfile.write(data)
    openfile.close()

And this is my error message:

Error:
    openfile= open(files,"rt")

FileNotFoundError: [Errno 2] No such file or directory: 'test2.txt'

I hope this question is correcly made since I am new to booth python and this forum.

What I would like to achive is to understand why I got this error message. Dont get it. And if possible get some feedback of the code if I have the correct approach.

does 'text.txt' actually exist?
using pathlib, you can narrow down the files you are interested in.
example list only .py files in src directory:

>>> from pathlib import Path
>>> path = Path('./src')
>>> files = [x for x in path.iterdir() if x.is_file() and x.suffix == '.py']
>>> for file in files:
...     print(file.name)
