I create a function to download an FTP Server directory and try to create it before in local and I miss an error

def Down_Dir(ftp, dir):

    ftp.cwd('\datos')
    try:       
        os.makedirs(os.getcwd()+"\"+dir)
    except OSError as e:
        if e.errno != errno.EEXIST:
            raise      

    os.chdir(os.getcwd()+"\"+dir)

This is the error that gives me:

Traceback (most recent call last):
  File "Pruebas_Arrays.py", line 267, in <module>
    conexionFtp(elemento[0],elemento[1],elemento[2],elemento[3],elemento[4],elemento[5],elemento[6], marcaTiempo, elemento[7])

    with self.transfercmd(cmd, rest) as conn:

    resp = self.sendcmd(cmd)

    return self.getresp()

I do not know if this will solve your problem but the best thing when working with directories is to use os.path.join This way your program would be:

def Down_Dir(ftp, dir):

    ftp.cwd('\datos')
    try:       
        os.makedirs(os.path.join(os.getcwd(),dir)
    except OSError as e:
        if e.errno != errno.EEXIST:
            raise      

    os.chdir(os.path.join(os.getcwd(),dir))
