una lista che non contiene
' ', 'pippo' , 'pluto'
Allora vuoi che tutte e tre le condizioni siano soddisfatte allo stesso
tempo: quindi un and.. per esempio
>>> l = [' ', 'pippo', 'pluto', 'peppa pig', 'mario', 'foo', 'homer']
>>> new_list = []
>>> for word in l:
if word != ' ' and word != 'pippo' and word != 'pluto':
print word, "oh yes!"
new_list.append(word)
else:
print word, 'bye bye..'
bye bye..
pippo bye bye..
pluto bye bye..
peppa pig oh yes!
mario oh yes!
foo oh yes!
homer oh yes!
>>> new_list
['peppa pig', 'mario', 'foo', 'homer']
Qualche altro esempio...
>>> word == 'pippo'
>>> word == ' ' or word == 'pippo' or word == 'pluto'
True
>>> word != ' ' or word != 'pippo' or word != 'pluto'
True
>>> word2 = 'mario'
>>> word2 == ' ' or word == 'pippo' or word == 'pluto'
True
>>> word2 == ' ' or word2 == 'pippo' or word2 == 'pluto'
False
>>> word2 != ' ' or word2 != 'pippo' or word2 != 'pluto'
True
>>> word2 != ' ' and word2 != 'pippo' and word2 != 'pluto'
True
>>> not word == ' ' or not word == 'pippo' or not word == 'pluto'
True
>>> not word2 == ' ' or not word2 == 'pippo' or not word2 == 'pluto'
True
Ciao
