ConceptPython (United Kingdom pronunciation:/?pa?θ?n/American pronunciation:/?pa?θɑ?n/) is an object-oriented, interpreted computer programming language, invented by Dutch Guido van Rossum in 1989, and the first public offering was released in 1991. featuresPython is purely free software, the source code and the interpreter CPython follow the GPL (GNU general public License) protocol, with a rich and powerful library, a concise and clear syntax, one of the features is mandatory whitespace (white
In my opinion, the process of implementing UI Automation testing has always been a happy thing, and maintaining them is just like a nightmare, especially BVT testing the build of each CI, and because development doesn't tell you any changes to the UI, the test results you get will be red. However, for projects with relatively stable interfaces, there are a number of projects required for regression testing, and a high ROI for UI Automation.I recently implemented a UI Automation test on Mac OSX f
As we all know, Python is known for its elegance, simplicity, low threshold, and can be engaged in Linux operations, Python web site engineers, Python automation testing, data analysis, artificial intelligence and other positions, pay rise trend. A lot of people want to learn python, so what are the 0 basic Python learning basics?python Primer One: Interpreter. python is an object-oriented, interpretive computer programming language, so you have to understand the interpreter to learn python well

Code should is written in a-the-does not disadvantage-other implementations of Python (PyPy, Jython, Ironpytho N, Cython, Psyco, and such). For example, does not rely on CPython ' s efficient implementation of in-place-string concatenation for statements in the F orm A + = b or a = a + b . Those statements run more slowly in Jython.

over 23 years old, it was originally released in 1991, earlier than HTTP 1.0 protocol 5 and earlier than Java 4. At present, there is a famous example of using Python early in 1996: Google's first successful web crawler.If you're curious about the long history of Python, Python's author Guido van Rossum has prepared the whole story for you.

results in the same Python code being executed under both interpreters. If your code is to be executed under PyPy, you need to understand the differences between PyPy and CPython.(4) JythonJython is a Python interpreter running on the Java platform that compiles python code directly to Java bytecode execution.(5) IronPythonIronPython is similar to Jython, except that IronPython is a Python interpreter running on the Microsoft.

Running Python at the command line is starting the CPython interpreter2.ipython:ipython is an interactive interpreter based on CPython, meaning that IPython is only enhanced interactively, but the functionality and CPython of executing Python code are exactly the same.

(crouching trough, look at others)Python's application involves every aspect! Don't say it, too much. Python is interpreted as a language:Python generates bytecode files during execution, but bytecode files are not saved and the next time they are re-interpreted to executePython bytecode files are also retained, only when the module is importedPyhon code cannot encrypt (now all popular open source, add what secret!) )Types of Python interpreters:

Personal opinion----This is a very good place for me to write class and Python scripts for test engineers, it's clear that Python scripts are easier to start with and lower thresholds. Easy to generalize, and Python's rich third-party libraries also have great scalability. But the problem now is the problem of Debug. Because the order in which they are executed is Monkeyrunner.jar->jython->python script. So in eclips, whether we specify Monkeyrunner
CPython is the python that is specifically implemented in C, which is the original python.
The word cpython is used because Python has other implementations, such as Jython, the Java version of Python, and the brain-burning pypy, which is also implemented using Python.
The following is an official description of CPython:
CPython is Guido van Rossum ' s reference version of the Python computing language. It ' s most often called simply "Python"; Speake
