Question
Write a function that takes a string (a) and a number (n) as argument. Return the nth character of 'a'.
Solution
Sure, here is a Python function that does what you asked for:
def nth_character(a, n):
if n <= len(a):
return a[n-1]
else:
return "Index out of range"
This function takes a string a and a number n as arguments. It checks if n is less than or equal to the length of the string a. If it is, it returns the nth character of a (Python uses 0-based indexing, so we subtract 1 from n). If n is greater than the length of a, it returns a message saying "Index out of range".
