Python Introduction | JNTUA | R19 | UNIT 1 | Functions
This document discusses functions in Python programming. It covers parameters and arguments, how local variables only exist within a function, and the differences between fruitful functions that return values and void functions that do not return values. Some built-in functions like math.sqrt require arguments, while math.pow requires two arguments for the base and exponent. Local variables declared within a function only exist in that function's scope. Fruitful functions like math.sqrt that returns a float value, while void functions like a greeting function that prints a value but does not return it explicitly.

Comp 220 ilab 7 of 7
This lab introduces students to the concepts of polymorphism, early binding, late binding, abstract classes, and virtual class functions. This will be done in the context of performing calculations on basic geometrical shapes. Polymorphism is a very powerful extension of inheritance, and by using pointers to the base class, it allows access to derived class objects and their functions based on the context that they are called in.
The lab will require the creation of a base geometric class, called Shape, and two sub classes, Circle and Rectangle, that are derived public from the class Shape. From there, objects of both the Circle and the Rectangle classes will be created, as will an array of pointers to the base class Shape. By using the instantiated objects and the object pointers, both static and dynamic binding will be demonstrated.

Recursion is defined as a function calling itself and examples of valid and infinite recursion are provided. The document also covers taking keyboard input in Python using the input function.
Application layer protocols
The document discusses several application layer protocols used in TCP/IP including HTTP, HTTPS, FTP, and Telnet. HTTP is used to access resources on the world wide web over port 80 and is stateless. HTTPS is a secure version of HTTP that encrypts communications over port 443. FTP is used to transfer files between hosts but sends data and passwords in clear text. Telnet allows users to access programs on remote computers.
Internet connectivity
Internet connectivity relies on a global network of routers that carry data packets from IP protocols from source to destination. Sources send data packets to destinations using standardized IETF formats. Internet connectivity principles involve routers transferring data packets across a global network using IP protocols and standardized formats.
Introduction for internet connectivity (IoT)
The document discusses key concepts related to internet connectivity including protocols, headers, packets and network interfaces. It defines common terms like IP header, TCP header, packet, IP address, port, socket and host. Packet refers to a set of bytes that travels through routers until reaching its destination. Headers include parameters encoded according to the IP and TCP protocols and travel with a packet. Network interfaces link layers and addresses and are identified by ports.
web connectivity in IoT
This document discusses various protocols for web connectivity, including communication gateways, HTTP, SOAP, REST, and WebSockets. Communication gateways allow different protocols to be used at each end of a connection. HTTP is the most widely used application layer protocol and uses request/response methods. SOAP is an XML-based protocol for exchanging objects between applications. REST is a simpler alternative to SOAP that uses HTTP methods like GET, POST, PUT and DELETE. WebSockets enable bidirectional communication over a single TCP connection.
message communication protocols in IoT
The document discusses various protocols for web connectivity and message communication, including request/response, publish/subscribe, resource directories, and pull/push data models. It defines terminology and describes several protocols in more detail, such as CoAP-SMS which uses SMS for message transport, CoAP-MQ which uses a message queue, and MQTT which is an open-source M2M protocol that uses topics and a broker.
web communication protocols in IoT
This document discusses various web communication protocols used for connectivity of devices over constrained and unconstrained environments. It describes protocols like CoAP, DTLS, JSON and TLV formats that allow small devices with limited resources to communicate securely over the web. CoAP is a specialized web transfer protocol that uses request/response model and supports resource discovery. DTLS provides security services like integrity, authentication and confidentiality for UDP-based applications. JSON and TLV are compact data formats used for message transmission.
introduction for web connectivity (IoT)

The document discusses various Python programming concepts including control statements, loops, strings, files and string manipulation. Control statements like if-else are used to conditionally execute code. Loops like for and while are used to repeatedly execute code while a condition is true. Strings can be manipulated using indexing, slicing and other string methods. Files can be read from and written to using file handling methods in Python.
Data enrichment
The document discusses the functions of a gateway in an IoT/M2M system. The gateway performs data enrichment, consolidation, and device management. It has several key functions including transcoding data formats, ensuring privacy and security, gathering and enriching data from devices, aggregating and compacting data, and managing device identities, configurations, and faults.
Communication technologies
This document discusses various wireless and wired communication technologies used for Internet of Things (IoT) systems, including Near-Field Communication (NFC), RFID, Bluetooth, ZigBee, Wi-Fi, cellular networks, USB, and Ethernet. It provides details on the standards, features, modes of operation, and applications of these different technologies for physical and data link layer communication functions in IoT/M2M systems.
M2M systems layers and designs standardizations
The document discusses standards and standardization bodies for Internet of Things (IoT) systems. The Internet Engineering Task Force (IETF), International Telecommunication Union (ITU-T), European Telecommunication Standards Institute (ETSI), and Open Geospatial Consortium (OGC) have all proposed standards and reference models for IoT layers, communication, and device/sensor capabilities. Specifically, ETSI defined domains and capabilities for machine-to-machine communication systems, while IETF, ITU-T, and OGC focused on network layers, transport protocols, and sensor discovery/metadata.
Business models for business processes on IoT
The document discusses business models for business processes on the Internet of Things. It covers key topics like IoT applications, business models, value creation using IoT, and business model scenarios for IoT. Business models need innovation to adapt to new customer access and interactions enabled by technologies like cloud computing and mobile communications. Value is created on IoT through addressing emergent needs, information convergence, and recurrent revenue from networked products. Example business model scenarios for IoT leverage data from multiple sources like sensors, M2M, and open data.

How to Make a Field Mandatory in Odoo 17
In Odoo, making a field required can be done through both Python code and XML views. When you set the required attribute to True in Python code, it makes the field required across all views where it's used. Conversely, when you set the required attribute in XML views, it makes the field required only in the context of that particular view.
