Given a string, check whether it is a panagram or not. A panagram is a sentence that uses every letter at least once. The most famous example is: he quick brown fox jumps over the lazy dog. Note: A panagram in one language isn't necessarily a panagram in another. This module assumes the english language. Hence, the Finnish panagram 'Trkylempijvongahdus' won't pass for a panagram despite being considered a perfect panagram in its language. However, the Swedish panagram 'Yxmrdaren Julia Blomqvist p fktning i Schweiz' will pass despite including letters not used in the english alphabet. This is because the Swedish alphabet only extends the Latin one. Returns whether the input string is an English panagram or not. Parameters: string str: A sentence in the form of a string. Returns: A boolean with the result.
