Question

Which of the following expressions results in an error?

(a) float(‘10’)

(b) int(‘10’)

(c) float(’10.8’)

(d) int(’10.8’)

I had been asked this question during an interview.

This intriguing question comes from Precedence and Associativity in chapter Precedence and Associativity, Bitwise & Boolean of Python

Answer 1

The correct answer is (d) int(’10.8’)

The best I can explain: All of the above examples show explicit conversion. However the expression int(’10.8’) results in an error.
