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 ]

Grid: -Information service -Security Service -Data management -Execution Manageement Cloud: - Maintains up-to-date information of resources -Create VMs according to user requirement -Application deploment -User management 2) What are the different cloud standards? -Interoperability standards -Security standards -Portability Standards -Governance and Risk standards 3) What are the two different sub-systems in Cloud computing ? -Management sub system -Resource sub system 4)What is Cloud compouting? The promise of cloud computing is ubiquitous access to a broad set of applications and services, which are delivered over the network to multiple customer. 5) Why we need specialized network for Cloud services? The public Internet is the simplest choice for delivering cloud-based services. In this model, the cloud provider simply purchases Inter

Cloud Case Study Part-2

Present case study is in Health Care:   Practo Technologies was formed in year 2008. The vision of the company was to make medical information digitally accessible to patients and doctors. With all these features at pleasing price, solutions providers like Practo aimed to create the most efficient healthcare experience for people in India and gradually around the world. The aim was to improve the patient experience for finding and meeting a doctor.   Traditionally the healthcare records were created manually and stored on shelves. Managing of records stored in files traditionally was of not much use. With the evolution of technology, there has been a paradigm shift in the manner the healthcare industry functions.   The medical records are electronically stored and managed. With the acceptance of cloud computing the healthcare patient data is stored at a remote server location on the internet.   The following companies offering CLOUD based health care
