Python Interview Questons nswers
1) What is Python? What are the benefits of using Python?
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.
2) What is PEP 8?
PEP 8 is a coding convention, a set of recommendation, about how to write your Python
code more readable.
3) What is pickling and unpickling?
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.
4) How Python is interpreted?
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.
5) How memory is managed in Python?
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.
6) What are the tools that help to find bugs or perform static analysis?
