Create a list of candidate strings by applying an edit operation

# data
word = 'dearz' # 🦌

Find all the ways you can split a word into 2 parts !

# splits with a loop
splits_a = []
for i in range(len(word)+1):
    splits_a.append([word[:i],word[i:]])

for i in splits_a:
    print(i)

['', 'dearz']
['d', 'earz']
['de', 'arz']
['dea', 'rz']
['dear', 'z']
['dearz', '']

# same splits, done using a list comprehension
splits_b = [(word[:i], word[i:]) for i in range(len(word) + 1)]

for i in splits_b:
    print(i)

('', 'dearz')
('d', 'earz')
('de', 'arz')
('dea', 'rz')
