Is the following Python code valid?
>>> a=(1,2,3,4) >>> del a
What will be the output of the following Python code?
>>> a=(0,1,2,3,4) >>> b=slice(0,2) >>> a[b]
>>> a,b,c=1,2,3 >>> a,b,c
>>> a,b=1,2,3
>>> a=(1,2) >>> b=(3,4) >>> c=a+b >>> c
>>> a,b=6,7 >>> a,b=b,a >>> a,b
>>> import collections >>> a=collections.namedtuple('a',['i','j']) >>> obj=a(i=4,j=7) >>> obj
>>> a=2,3,4,5 >>> a
>>> a=(2,3,1,5)
>>> a.sort()
>>> a
