Python map() and lambda() Use Cases and Examples

-
Image
 In Python, map() and lambda functions are often used together for functional programming. Here are some examples to illustrate how they work. Python map and lambda top use cases 1. Using map() with lambda The map() function applies a given function to all items in an iterable (like a list) and returns a map object (which can be converted to a list). Example: Doubling Numbers numbers = [ 1 , 2 , 3 , 4 , 5 ] doubled = list ( map ( lambda x: x * 2 , numbers)) print (doubled) # Output: [2, 4, 6, 8, 10] 2. Using map() to Convert Data Types Example: Converting Strings to Integers string_numbers = [ "1" , "2" , "3" , "4" , "5" ] integers = list ( map ( lambda x: int (x), string_numbers)) print (integers) # Output: [1, 2, 3, 4, 5] 3. Using map() with Multiple Iterables You can also use map() with more than one iterable. The lambda function can take multiple arguments. Example: Adding Two Lists Element-wise list1 = [ 1 , 2 , 3 ]

3 top IT Skills every new IT Professionals learn to progress in software career

it skills
What are the skills needed by the new IT professionals or job seekers who help the organisation transition to IT-as-a-Service. In order to lead their organisations to the cloud, IT professionals must focus on three fundamental areas:

Core Virtualisation Skill Sets

IT professionals must think and operate in the virtual world. No longer can they be tied to the old paradigm of physical assets dedicated to specific users or applications.

They must think in terms of “services” riding on top of a fully virtualized infrastructure, and how applications will take advantage of shared resources with both servers and storage.

This requires comprehensive skills in both server and storage virtualization technology, and enough experience as a practitioner to understand the intricacies and critical elements of managing virtual platforms.

Rules of Old IT and New IT

Cross-training Competency

Leaders of IT innovation cannot be completely siloed and hyper-focused. Although there will still be a need for deep domain expertise, the architects who lead the transition must have broad skills.

They must understand enough about security, networking, storage, servers, databases, and applications to develop a vision and look at infrastructure holistically. 

As infrastructure is deployed and managed, these lead architects will then consult with, and rely on domain experts. To broaden their skills, it will be necessary for IT professionals to invest time in acquiring skills in fields adjacent to their own.

Business Skills

IT professionals will take on the role of business advisors and, in some ways, “brokers” of services. 

 They must collaborate with line-of-business and application owners, guiding the discussion to answer the questions “Where should this workload run?” “Cloud or dedicated?” “Public? Private? Hybrid?” 

 The new architect will be part technologist, part product manager, and part salesperson, helping assess needs and guiding end-users to the appropriate technology solution for a set of business requirements. 

Communication Skills

The requirements include not only communication and customer service skills, but also business analytics and finance, in order to align the right solution to end-user budgets.

 With these skills serving as the foundation for cloud computing leadership, it is more critical than ever that companies hire this talent or invest the time and money to develop it internally. However, organizational changes will be just as critical as evolving the skills within the IT organization.

SQL Query: 3 Methods for Calculating Cumulative SUM

SQL provides various constructs for calculating cumulative sums, offering flexibility and efficiency in data analysis. In this article, we explore three distinct SQL queries that facilitate the computation of cumulative sums. Each query leverages different SQL constructs to achieve the desired outcome, catering to diverse analytical needs and preferences. Using Window Functions (e.g., PostgreSQL, SQL Server, Oracle) SELECT id, value, SUM(value) OVER (ORDER BY id) AS cumulative_sum  FROM your_table; This query uses the SUM() window function with the OVER clause to calculate the cumulative sum of the value column ordered by the id column. Using Subqueries (e.g., MySQL, SQLite): SELECT t1.id, t1.value, SUM(t2.value) AS cumulative_sum FROM your_table t1 JOIN your_table t2 ON t1.id >= t2.id GROUP BY t1.id, t1.value ORDER BY t1.id; This query uses a self-join to calculate the cumulative sum. It joins the table with itself, matching rows where the id in the first table is greater than or
