1. Explain PEP 8 in Python ? Answer: PEP 8 is considered as a coding convention, a set of recommendation, about how to write your Python code more readable. |
2.Explain generators in Python?
Answer:
The way of implementing iterators are known as generators. It is a normal function except that it yields expression in the function.
3.. How to convert string as a variable name in python?
Answer:
The simplest way to convert string as a variable name is by using vars().
4. What is the use of Def keyword for method?
Answer:The Def keyword in python is used to form a new user-defined function. The def keywords mark the beginning of function header. The functions are the objects through which one can easily organize the code.
5.Can we use hybrid inheritance in Python?
Answer:
No, python doesn’t support hybrid inheritance. But we can use straight method and round diamond method we can achieve it.
6. range vs xrange in Python?
Answer:
In python the range and xrange are two functions that are used repeat number of time in for loops. The major difference between range and xrange is that the xrange returns the xrange object while the range returns a python list objects. The xrange is not capable for generating the static list at run-time. On the other hand range can do that.

7.What is monkey patching in Python?
Answer:
You can make dynamic modifications to a module or class during the run-time. This process is called monkey patching in Python.

An inbuilt Python module helpful in creating GUI applications is known as Tkinter.
14.Explain multiple exception handling in python?Answer:
To handle multiple exception in python you can use try statement. You can also use these blocks:
Answer:
A tuple is a group of specific data structure under Python is immutable. They mean similar to progressions, really prefer the lists. Also, that tuples follow parentheses as including, but these programs have square sections in their syntax.
16.What is the use of Isalpha() In Python?
Answer:
Python has been provided that built-in isalpha() value function for each string manipulating purpose. It reflects the True value function if all types in this string value function are of alphabet type number, else value function it returns False.
17.What does the meaning of Slicing in python?
Answer:
Python Slicing is defined as Lists of Tuples and Arrays Volume function. The Lists element function has a default bit fo the functionality while slicing. If there is a no consequence of before that first colon, it expects to begin at the start index of the list.
18.What is the use of beautifulSoup module in python?
Answer:
We are using the module for pulling the data from HTML and XML files
19.What is TKIner in python?
Answer:
TKIner is a python inbuilt library for developing the GUI

Answer:
Pip is a python package installer. Whenever we need third party library like paramiko,pandas etc
We can use pip command to install the packages
Ex: pip install paramiko
21.What is pandas in python?
Answer:
Pandas is data science library which deal with large set of data. pandas define data as data frame and processes it. Pandas is a third party library which we need to install.
22.What is decorators in python?
Answer:
The decorators are special functions which will very useful when tweaking the function or class.it will modify the functionality of another function.
An inbuilt Python module helpful in creating GUI applications is known as Tkinter.
14.Explain multiple exception handling in python?Answer:
To handle multiple exception in python you can use try statement. You can also use these blocks:
- The try/except blocks
- The finally blocks
- The raise keywords
- Assertions
- Defining your own exception

Answer:
Map and filter are called higher order functions which will take another functions as an argument.
25.Why a tuple is best over a list in python?
Answer:
We can use tuple as a dictionary key because it is hash able and tuple accessing very fast compare to a list.
26.What is list in python?
Answer:
A list is a mutable sequential data items enclosed with in[] and elements are separated by comma.
Ex: var_list=[5,5.2,’nishant’,’Besant’,[6,9,5]]
In a list we can store any kind of data and we can access them by using index

Answer:
If the objects translated from string then it seems to be pickling
If the String is dumped to objects then it seems to unpickling.

Answer:
Args:
It doesn’t know how many arguments are used.
