Write a function x_at_either_end(string) that takes a string string as a parameter, which may be empty, and returns a boolean. It returns True if and only if the string string starts or ends with the lower-case character x.We recommend using the startswith and endswith methods of str.
Question
Write a function x_at_either_end(string) that takes a string string as a parameter, which may be empty, and returns a boolean. It returns True if and only if the string string starts or ends with the lower-case character x.We recommend using the startswith and endswith methods of str.
Solution
Sure, here is a Python function that fulfills your requirements:
def x_at_either_end(string):
return string.startswith('x') or string.endswith('x')
This function takes a string as an argument and checks if it starts or ends with the lowercase character 'x'. It uses the startswith and endswith methods of the str class in Python, which return True if the string starts/ends with the specified value, and False otherwise. The or operator is used to return True if either of the conditions is True.
