Python: Compare `to string` conversion performance

main.py

from timeit import timeit

from dataclass_wizard.utils.type_conv import as_str


n = 100_000

print('(int) as_str():'.ljust(25), timeit('x = 42; as_str(x)', globals=globals(), number=n))
print('(int) str():'.ljust(25), timeit('x = 42; str(x)', globals=globals(), number=n))
print('(int) empty_if_none():'.ljust(25), timeit("x = 42; '' if x is None else str(x)", globals=globals(), number=n))
print()
print('(str) as_str():'.ljust(25), timeit('x = "hello world!"; as_str(x)', globals=globals(), number=n))
print('(str) str():'.ljust(25), timeit('x = "hello world!"; str(x)', globals=globals(), number=n))
print('(str) empty_if_none():'.ljust(25), timeit('x = "hello world!"; "" if x is None else str(x)', globals=globals(), number=n))
print()
print('(bool) as_str():'.ljust(25), timeit('x = True; as_str(x)', globals=globals(), number=n))
print('(bool) str():'.ljust(25), timeit('x = True; str(x)', globals=globals(), number=n))
print('(bool) empty_if_none():'.ljust(25), timeit("x = True; '' if x is None else str(x)", globals=globals(), number=n))

Results show that approach #2 or #3 are at least 2x faster than the first approach with as_str().
