example usage of casefold, Counter and count
# setup main tuple
items=("Extra-Terrestrial", "Alien", "Planet", "Star",
"Galaxy", "Universe", "Black Hole", "White Hole",
"Astronomy", "Dark-Matter", "Dark-Energy")
# setup comparison tuple
compare=("extra-terrestrial", "alien")
''' use casefold -py3(or upper / lower -py2)
for context insensitive comparison '''
for item in items:
if any(i.casefold() in item.casefold() for i in compare):
print(item)
''' use counter to count all words in tuple'''
print(f'\n{Counter(compare)}\n')
''' use count to count how many times comparative
words appear in tuple'''
for c in compare:
tense="time" if items.count(c.title())==1 else "times"
print(f'{c.title()} appears {items.count(c.title())}
Output:
Extra-Terrestrial
Alien
Counter({'extra-terrestrial': 1, 'alien': 1})
Extra-Terrestrial appears 1 time in ('Extra-Terrestrial', 'Alien', 'Planet', 'Star', 'Galaxy', 'Universe', 'Black Hole', 'White Hole', 'Astronomy', 'Dark-Matter', 'Dark-Energy', '')
Alien appears 1 time in ('Extra-Terrestrial', 'Alien', 'Planet', 'Star', 'Galaxy', 'Universe', 'Black Hole', 'White Hole', 'Astronomy', 'Dark-Matter', 'Dark-Energy', '')
**note :
.count only takes into account the exact word - so words like
"alienesque" or "alien ship" would not be recognised as containing
the word alien.
