Script works on Linux , but not on Windows [flask app]-CodePudding

I am trying to write a script that modifies several LaTeX files from the templates I created and places them in new folders [this script will be used for a flask application ]. I have problems when I use the following code:

 # Write results
     with open(outputname   ".tex", 'w ') as f:
          f.write(filedata)

     # Convert result.tex to result.pdf
     proc = subprocess.Popen(['pdflatex', '-interaction=nonstopmode', outputname '.tex'])
     proc.communicate()

     # Remove unnecessary files
     proc = subprocess.Popen(['del', outputname   '.tex'])
     proc = subprocess.Popen(['del', outputname   '.aux'])
     proc = subprocess.Popen(['del', outputname   '.log'])
     proc = subprocess.Popen(['move', outputname   ".pdf", outputfolder])
     proc.communicate()
     return 

def clean_repo(dir, ext):
    filelist = [ f for f in os.listdir(dir) if f.endswith(ext) ]
    for f in filelist:
        os.remove(os.path.join(dir, f))

It works on lunix except that on windows only one document is modified and generated in PDF, the generated PDF is not moved to the created folder, the .aux, .log and .tex type files are not deleted .

application script :

CodePudding user response：

 proc = subprocess.Popen(['del', outputname   '.tex'])
 proc = subprocess.Popen(['del', outputname   '.aux'])
 proc = subprocess.Popen(['del', outputname   '.log'])
 proc = subprocess.Popen(['move', outputname   ".pdf", outputfolder])

This piece relies on availability of certain command, to avoid that use following functions

these are inside standard library, so you do not need to install anything just add import os and import shutil to use them.
