1. Which line of code produces an error?

(a)  “one” + “2”

(b)  ‘5’ + 6

(c)   3 + 4

(d)  “7” + ‘eight’

• (a)

• (b)

• (c)

• (d)

Answer explanation

The correct answer is (b) '5' + 6.

In Python, you cannot concatenate (add) a string and an integer directly. '5' is a string and 6 is an integer, so attempting to add them together will result in a TypeError.

Here's a breakdown of the other options:

(a) "one" + "2" is a valid string concatenation.

(c) 3 + 4 is a valid integer addition.

(d) "7" + 'eight' is a valid string concatenation.

1. Identify the invalid variable name in python?

(a)  this_is_a_variable = 7

(b)  abc = 10.22

(c)  ThisBook = “python”

(d)  %name = “xyz”

• (a)

• (b)

• (c)

• (d)

Find the output of this code:

• loop

• No Output

• Infinite Looping

• Error
