safer way to close. LGTM.
As a side note, the finally
block also hooks into the __del__
behavior of generators
def my_gen():
try:
for j in range(5):
print('in loop', j)
yield j
finally:
print('finally')
In [3]: list(my_gen())
in loop 0
in loop 1
in loop 2
in loop 3
in loop 4
finally
Out[3]: [0, 1, 2, 3, 4]
In [4]: g = my_gen()
In [5]: next(g)
in loop 0
Out[5]: 0
In [6]: next(g)
in loop 1
Out[6]: 1
In [7]: del g
finally
If you dig into the __die() method in pymongo driver, it does something similar. It doesn't hurt being safe
