pycc 2.0.0

基本示例

符号表（变量）查找一开始似乎并不昂贵。

# awesome_module.pyMAGIC_NUMBER=7forxinxrange(10000000):MAGIC_NUMBER*MAGIC_NUMBER

现在让我们做一个粗略的基准。

# Generate bytecode file to skip compilation at runtime.
python -m compileall awesome_module.py
# Now get a simple timer.
time python awesome_module.pyc

# real    0m0.923s
# user    0m0.920s
# sys     0m0.004s

PYCC对此有何评论？

pycc-transform awesome_module.py --constants

MAGIC_NUMBER=7forxinxrange(10000000):(7*7)

很好，但那有什么用呢？

pycc-compile awesome_module.py -- constants
time python awesome_module.pyc

# real    0m0.473s
# user    0m0.469s
# sys     0m0.004s

如何获得它

pip install pycc
