Python Practice 5 - Tuple

Which of the following is a Python tuple?

• [1, 2, 3]

• (1, 2, 3)

• {1, 2, 3}

• {}

Suppose t = (1, 2, 4, 3), which of the following is incorrect?

• print(t[3])

• t[3] = 45

• print(max(t))

• print(len(t))

What will be the output of the following Python code?

>>>t=(1,2,4,3)

>>>t[1:3]

• (1, 2)

• (1, 2, 4)

• (2, 4)

• (2, 4, 3)

What will be the output of the following Python code?

>>>t=(1,2,4,3)

>>>t[1:-1]

• (1, 2)

• (1, 2, 4)

• (2, 4)

• (2, 4, 3)

What will be the output of the following Python code?

>>>t = (1, 2)

>>>2 * t

• (1, 2, 1, 2)

• [1, 2, 1, 2]

• (1, 1, 2, 2)

• [1, 1, 2, 2]

What will be the output of the following Python code?

>>>my_tuple = (1, 2, 3, 4)

>>>my_tuple.append( (5, 6, 7) )

>>>print len(my_tuple)

• 1

• 2

• 5

• Error

What will be the output of the following Python code snippet?

d = {"john":40, "peter":45}

print(d)

• “john”, 40, “peter”, 45

• {‘john’: 40, ‘peter’: 45}

• 40 and 45

• d = (40:”john”, 45:”peter”)

d = {"john":40, "peter":45}

d["john"]

• 40

• 45

• "john"

• "peter"

Suppose d = {“john”:40, “peter”:45}, to delete the entry for “john” what command do we use?

• d.delete(“john”:40)

• d.delete(“john”)

• del d[“john”]

• del d(“john”:40)

What will be the output of the following Python code snippet?

d = {"john":40, "peter":45}

print(list(d.keys()))

• [“john”, “peter”]

• [“john”:40, “peter”:45]

• (“john”, “peter”)

• (“john”:40, “peter”:45)
