Compare element of list with line of file : if match, delete line

[silfer]

Hi

I have a list:

['123;G-12;http//www.g.ch/bidule_12', '456;G-422;http//www.g.ch/bidule_422', '789;G-562;http//www.g.ch/bidule_562']

I have a csv.file with following lines:
123;G-12;http//www.g.ch/bidule_12
456;G-422;http//www.g.ch/bidule_422
789;G-562;http//www.g.ch/bidule_562
breu
5555;G-0;http//www.g.ch/bidule_0

As a result, I want only these lines remaining in my csv.file:
breu
5555;G-0;http//www.g.ch/bidule_0

So, my python script is supposed to compare each element of my list with each line ; if they match, the line is deleted in the csv.file.

I tried (for a long time) loop + "replace" or "re.sub" with no success.

Any idea?

Thanks

What you have done so far?

g_complet_resultat = open("g_complet_resultat.csv", "r") # file including the mentioned lines
NumeroLigne = 0
for line in g_complet_resultat: # mentioned list
    NumeroLigne_supprimees = 0
    for ligne_supprimee in g_lignes_supprimees_en_liste_result:
        g_cherche = re.search(str(ligne_supprimee), line)
        if g_cherche:
            g_replace = re.sub(line, '', line)

    NumeroLigne_supprimees = +1
NumeroLigne = +1
g_resultat.close()

Problem : content of g_complet_resultat.csv does not change (no lines deleted).

This is because you open it for read and not for write.
I suggest you to create a second file for the output to be more robust and not lose data while you're testing the script.

g_lignes_supprimees_en_liste_result = ['123;G-12;http//www.g.ch/bidule_12', '456;G-422;http//www.g.ch/bidule_422', '789;G-562;http//www.g.ch/bidule_562']
with open("g_complet_resultat.csv", "r") as f_in:
    with open("out.csv", "w") as f_out:
        for line in f_in:
            # Removes the '\n' to compare with elements in the list
            line = line[:-1]
            if line not in g_lignes_supprimees_en_liste_result:
                f_out.write(line + '\n')

Is it a requisite to modify the same file? If so, let me know.

SO easy for you, gontajones.
I am grateful.
