quitWhen you type quit at the help’s command prompt, python shell prompt will appear by closing the help window automatically

  1. Names must start with a letter or _.
  2. Names must contain only letters, digits, and _.

Pickle module accepts any Python object and converts it into a string representation and dumps it into a file by using dump function, this process is called pickling.  While the process of retrieving original Python objects from the stored string representation is called unpickling.

By using the inbuilt function str().

Framework called Web2py, PAMIE (Python automation Module for I. E.), The py.test framework

There are good tools for helping Python development such as Notepad++ with the PyNPP plugin and Eclipse with PyDev and PyUnit

PEP 8 is a coding convention, a set of recommendation, about how to write your Python code more readable.

copy.copy () or copy.deepcopy()

Python language is an interpreted language. Python program runs directly from the source code. It converts the source code that is written by the programmer into an intermediate language, which is again translated into machine language that has to be executed.

print(‘hello’ + ‘-‘ + ‘how’ + ‘-‘ + ‘are’ + ‘-‘ + ‘you’)

Python is a programming language with objects, modules, threads, exceptions and automatic memory management. The benefits of pythons are that it is simple and easy, portable, extensible, build-in data structure and it is an open source.

Generators are the means to implement iterators. It is a normal function except that it yields “expression” in the “function”.

No. Built-in functions such as max(), min(), filter(), map(), etc is not apparent immediately as they are available as part of standard module.To view them, we can pass the module ” builtins ” as an argument to “dir()”. It will display the built-in functions, exceptions, and other objects as a list.>>>dir(__builtins )

[‘ArithmeticError’, ‘AssertionError’, ‘AttributeError’, ……… ]

  1. To generate test data; parse test results; generate reports; testing API calls etc.
  2. Python to extract requirements from a Word document.
  3. For testing tasks automation, setting up environments for tests, extracting performance data, etc…
  4. Testers use Python extensively in many companies with Selenium for test automation.
  5. For writing desktop applications used by testers.
  6. Test data manipulation.
  7. To build test environment
  8. Testing with IronPython on .NET

  • Python memory is managed by Python private heap space. All Python objects and data structures are located in a private heap. The programmer does not have an access to this private heap and interpreter takes care of this Python private heap.
  • The allocation of Python heap space for Python objects is done by Python memory manager.  The core API gives access to some tools for the programmer to code.
  • Python also have an inbuilt garbage collector, which recycle all the unused memory and frees the memory and makes it available to the heap space.

Python performs some amount of compile-time checking, but most of the checks such as type, name, etc are postponed until code execution. Consequently, if the Python code references a user -defined function that does not exist, the code will compile successfully. In fact, the code will fail with an exception only when the code execution path references the function which does not exists.
