Test a Palindrome Check

is_palindrome(text) returns True when text reads the same forwards and backwards once capitals and spaces are ignored, and False otherwise. Spaces are the only characters it ignores, and an empty string counts as a palindrome.

Write test_ functions with assert that pass on a correct version and fail on broken ones.

Examples

is_palindrome("level")       # True
is_palindrome("Top spot")    # True
is_palindrome("python")      # False
