true

false

error

none

Q13 | >>>print len(my_tuple)

error

Q14 | What is the data type of (1)?

tuple

integer

list

both tuple and integer

Q15 | ])

now, a=(1,2,4)

now, a=(1,3,4)

now a=(3,4)

error as tuple is immutable

Q16 | )

too many arguments for sum() method

the method sum() doesn’t exist for tuples

Q17 | What type of data is: a=[(1,1),(2,4),(3,9)]?

array of tuples

list of tuples

tuples of lists

invalid type

Q18 | Is the following Python code valid?>>> a,b=1,2,3

yes, this is an example of tuple unpacking. a=1 and b=2

yes, this is an example of tuple unpacking. a=(1,2) and b=3

no, too many values to unpack

yes, this is an example of tuple unpacking. a=1 and b=(2,3)

Q19 | Tuples can’t be made keys of a dictionary.

true

false

Q20 | ,)

yes, a=(1,2,3,4) and b=(1,2,3,4)

yes, a=(1,2,3) and b=(1,2,3,4)

no because tuples are immutable

no because wrong syntax for update() method
