What will be the output of the following Python functions?

chr(‘97’)
chr(97)

For the first call chr('97'), the function chr() expects an integer representing a Unicode code point, not a string. When it receives the string '97', it attempts to convert it to an integer, but it raises a TypeError because it cannot directly convert a string to an integer in this context. Hence, it results in an error.

For the second call chr(97), the argument passed is an integer, which represents the Unicode code point for the character 'a'. Therefore, this call to chr() returns the character 'a'.

So, the output is "Error" for the first call and "a" for the second call.
