wholesale jewelry ring settings Did Python compile the text pre -compiled text

western jewelry pendants wholesale 1. Introduction
Relative to PY files, compilation into PYC and PYO is not much different from PY, but the loading speed of this module has increased, and the execution speed of the code is not improved. Generally, it is not necessary to use it. Take the initiative to compile PYC files, unless business provides to prevent the source code from leaking.
(1) What is pyc file
pyc is a binary file. It is a file generated by PY files and is generated. It is a Byte Code. It is improved, and PYC is a cross -platform bytecode, which is performed by Python's virtual machine. This is a concept similar to the Java virtual machine. The content of PYC is related to the version of Python. The PYC files compiled different versions of different versions are different. The Pyc file compiled 2.5 and Python in version 2.4 cannot be executed.
(2) What is PYO file
Pyo is the optimized compiled program Python -o source file to compile the source program as PYO file

2. Compile
The compilation of the Python file to PYC file (using commands), and then delete the source code.
(This file is similar to the class file in Java, but the 2.7 version of Python we use does not currently have
free version of counter -compilation tools, so it is not easy to crack at present, so you don't need to do it anymore Confusion)

(1) Command line compilation method:
python -m src/
echo compile finind ...
RM -RF SRC/*. PY

The compilation of PYO:
is to execute python -o -m py_compile file.py n
(2) Python program compilation method:
For separate compilation, you only need to use the Py_complie module. Can compile 2.7

The counter -compilation DEMO code:

import OS
import sys

DEF (file):
unpath = sys.
unpath = unpath [0: unpath.rfind (OS.SEP)]
newname = file [0: file.rfind (.)] .py nCommand = "python -u" unpath "scripts " File "> " Newname
try:
oS.System (Command)
except e:
print file
nif __name___main__: r r r r r r r r r r r r r

#Print unpath
print init
(E: test.pyc)
print finish
