Uh oh!
There was an error while loading. Please reload this page.
The public PyUnicodeWriter API enables overallocation by default and so is more efficient.
Benchmark:
python -m pyperf timeit \
-s 't = list[int, float, complex, str, bytes, bytearray, ' \
'memoryview, list, dict]' \
'str(t)'
Result:
1.49 us +- 0.03 us -> 1.10 us +- 0.02 us: 1.35x faster
Sorry, something went wrong.
