Problem with "while and a string of characters

[Faosry]

Okay, thanks but with this :

ligne1 = [2,0,5,5,1,4,4,2,1,3,5,3,2,4,2,1,4,4]                 
ligne2 = [0,0,0,5,1,3,1,2,2,5,3,2,4,4,1,3,5,2]
ligne3 = [3,0,3,0,4,5,0,1,0,4,3,1,0,3,5,2,5,1]

def facejaune90(ligne1,ligne2,ligne3):         
   m = ligne1[6]
   ligne1[6] = ligne3[6]
   ligne3[6] = ligne3[8]
   ligne3[8] = ligne1[8]
   ligne1[8] = m
   m = ligne1[7]
   ligne1[7] = ligne2[6]
   ligne2[6] = ligne3[7]
   ligne3[7] = ligne2[8]
   ligne2[8] = m
   m = ligne3[3]
   ligne3[3] = ligne1[17]
   ligne1[17] = ligne1[11]
   ligne1[11] = ligne3[12]
   ligne3[12] = m
   m = ligne3[4]
   ligne3[4] = ligne1[16]
   ligne1[16] = ligne1[10]
   ligne1[10] = ligne3[13]
   ligne3[13] = m
   m = ligne3[5]
   ligne3[5] = ligne1[15]
   ligne1[15] = ligne1[9]
   ligne1[9] = ligne3[14]
   ligne3[14] = m
   return ligne1,ligne2,ligne3

while (ligne1[8]!=4 and ligne3[5]!=1 and ligne3[12]!=0):
   ligne1,ligne2,ligne3 = facejaune90(ligne1,ligne2,ligne3)
   print("recherche en cours...")
print(ligne1)
print(ligne2)
print(ligne3)

The program not going in the "while". Why ? The conditions are true, so he must go inside. I don't understand...
