Rédiger « Angosso.jpg » $ s[i] = x item i of s is replaced by x s[i:j] = t slice of s from i to j is replaced by the contents of the iterable t del s[i:j] same as s[i:j] = [] s[i:j:k] = t the elements of s[i:j:k] are replaced by those of t (1) del s[i:j:k] removes the elements of s[i:j:k] from the list s.append(x) same as s[len(s):len(s)] = [x] (2) s.extend(x) same as s[len(s):len(s)] = x (3) s.count(x) return number of i‘s for which s[i] == x s.index(x[, i[, j]]) return smallest k such that s[k] == x and i <= k < j (4) s.insert(i, x) same as s[i:i] = [x] (5) s.pop([i]) same as x = s[i]; del s[i]; return x (6) s.remove(x) same as del s[s.index(x)] (4) s.reverse() reverses the items of s in place (7) s.sort([cmp[, key[, reverse]]])
