One, Python file types

Python File types:

1. Source code file: with "py" as extension, interpreted by Python program

(a)
# Cat test1.py
print "Hello world!"
# python test1.py
Hello world!
(b)
# Cat test1.py
#!/usr/bin/python (this line specifies to be interpreted in Python language)
print "Hello world!"
# chmod +x test1.py
#./test1.py
Hello world!

2. Byte code file: compiled to generate a file with the extension "PYc" (binary file)

Compilation Method--Import Py_compile
Py_compile.compile ("test1.py")
(a)
# Cat test2.py
Import Py_compile
Py_compile.compile ("test1.py")
# python test2.py
# ls
test1.py Test1.pyc test2.py

3. Optimized code files: optimized source files with the extension ". Pyo" (binary file)

# Python-o-M Py_compile test1.py
# ls
test1.py TEST1.PYC test1.pyo test2.py
