Learning Python Programming is one of the common trends now-a-days as it gives you opportunities to explore your career goals. Considering the pandemic situation if you wish to learn this then you can try for online courses offered by Coursera, Udemy or HP. The teachers are very interactive there and

Pandas is an open source python library which supports data structures for data based operations associated with data analyzing and data Manipulation . Pandas with its rich sets of features fits in every role of data operation,whether it be related to implementing different algorithms or for solving complex business problems.

Functional programming is a coding style where the main source of logic in a program comes from functions.

Incorporating functional programming in our codes means writing pure functions.

Pure functions are functions that cause little or no changes outside the scope of the function. These changes are referred to as

Slicing is a process used to select a range of elements from sequence data type like list, string and tuple. Slicing is beneficial and easy to extract out the elements. It requires a : (colon) which separates the start index and end index of the field. All the data sequence

Python has a multi-threading package ,but commonly not considered as good practice to use it as it will result in increased code execution time.

Python has a constructor called the Global Interpreter Lock (GIL). The GIL ensures that only one of your ‘threads’ can execute at one time.The process makes

Flask supports a database-powered application (RDBS). Such a system requires creating a schema, which needs piping the schema.sql file into the sqlite3 command. Python developers need to install the sqlite3 command to create or initiate the database in Flask.

Flask allows to request for a database in three ways:

before_request():

Self is an object or an instance of a class. This is explicitly included as the first parameter in Python. On the other hand, in Java it is optional. It helps differentiate between the methods and attributes of a class with local variables.

The self variable in the init method

Nested Lists :

• Python lists are efficient general-purpose containers that support efficient operations like insertion,appending,deletion and concatenation.
• The limitations of lists are that they don’t support “vectorized” operations like element wise addition and multiplication, and the fact that they can contain objects of differing types mean that Python must store

Whenever Python exits, especially those Python modules which are having circular references to other objects or the objects that are referenced from the global namespaces are not always de-allocated or freed.

It is not possible to de-allocate those portions of memory that are reserved by the C library.

On exit,

Python comes with some file-related modules that have functions to manipulate text files and binary files in a file system. These modules can be used to create text or binary files, update their content, copy, delete, and more.

Some file-related modules are os, os.path, and shutil.os. The os.path module has
