For Append To Extend
Sourcery refactoring id: for-append-to-extend
Description
Replace a for append loop with list extend
Before
games = []
for i in range(10):
for j in range(10):
if i != j:
games.append(play(i, j))
After
games = []
for i in range(10):
games.extend(play(i, j) for j in range(10) if i != j)
Explanation
Instead of looping through an iterator and appending to the list, we can make the intent clearer by explicitly stating that we are extending this list.
