Is the following Python code valid?
>>> a=(1,2,3) >>> b=a.update(4,)
What will be the output of the following Python code?
>>> a=[(2,4),(1,2),(3,9)] >>> a.sort() >>> a
nums = set([1,1,2,3,3,3,4,4])
print(len(nums))
a = [5,5,6,7,7,7]
b = set(a) def test(lst): if lst in b: return 1 else: return 0 for i in filter(test, a):
print(i,end=" ")
>>> a={5,4} >>> b={1,2,4,5} >>> a<b
>>> a={4,5,6} >>> b={2,8,6} >>> a+b
