Output of tuple creation with single element

What is the output of this code?

t = (5)
print(type(t))

Python

t = (5)
print(type(t))

A <class 'list'>

B <class 'int'>

C SyntaxError

D <class 'tuple'>

💡 Hint

Remember that parentheses alone do not create a tuple unless there is a comma.

Parentheses around a single value without a comma do not create a tuple. So (5) is just the integer 5 in parentheses, not a tuple.

Creating a tuple with one element

What is the output of this code?

t = (5,)
print(type(t))

Python

t = (5,)
print(type(t))

A <class 'int'>

B SyntaxError

C <class 'tuple'>

D <class 'list'>

💡 Hint

Check the comma after the element inside parentheses.

A comma after a single element inside parentheses creates a tuple with one element.

Output of tuple unpacking with multiple elements

What is the output of this code?

a, b, c = (1, 2, 3)
print(a + b + c)

Python

a, b, c = (1, 2, 3)
print(a + b + c)

A 6

B 123

C TypeError

D SyntaxError

💡 Hint

Unpacking assigns each tuple element to a variable.

The tuple elements 1, 2, 3 are assigned to a, b, c respectively. Their sum is 6.

Output of tuple creation without parentheses

What is the output of this code?

t = 1, 2, 3
print(type(t))

Python

t = 1, 2, 3
print(type(t))

A <class 'tuple'>

B <class 'list'>

C <class 'int'>

D SyntaxError

💡 Hint

Parentheses are optional when creating tuples with multiple elements.

Comma-separated values without parentheses create a tuple by default.

Output of nested tuple unpacking

What is the output of this code?

t = (1, (2, 3), 4)
a, (b, c), d = t
print(b * c + a + d)

Python

t = (1, (2, 3), 4)
a, (b, c), d = t
print(b * c + a + d)

A TypeError

B 10

C SyntaxError

D 11

💡 Hint

Unpack the nested tuple carefully and then do the math.

a=1, b=2, c=3, d=4; calculation is 2*3 + 1 + 4 = 6 + 1 + 4 = 11.
