In other programming language like C,C++, JAVA, we have a increment(++) and decrement(--) operator which increase and decrease the value respectively.example -a=3a++a will become 4a--a--a will become 2-But in python this type of operation is not validprogram -a=3a++print(a)a--a--print(a)output- 

Set in python are also similar as the list but in set items can never be repeated but in list items may repeated. Set is a immutable data type because in set , items value are not changes or index operation is not allowed.Even in set any kind of index operation is not allowed.Example of set:- S

TCP can not keep segment data secure against the message eavesdropping attacks. TCP transports stream data used in the application layer. Since TCP does not provide any data encryption functions, anyone can gain any valuable information. TCP can not protect connections against the unauthorized acces

TCP is a reliable protocol that guarantees delivery of individual packets from the source to the destination. This is accomplished through the use of an acknowledgement system where the receiving system informs the sender that it has received the packet successfully.

For information on installing and the initial configuration of TCP/IP, refer to the Transmission Control Protocol/Internet Protocol section in Networks and communication management. For any number of reasons, the person who administers your system might have to meet a certain level of security.

What is type casting -Conversion of one data type to another type is called type casting that means in programming at runtime we change the type of the data or variable which store data.Possible Type casting -int to floatfloat to intint to stringnumeric string to intlist to stringlist to setset to l

String and list both are the different data type of different domain and structure of both data type is different. So when we want to convert list to string, we must aware of string as well as list in python.Example of conversion- List=['Hello','String']And we want to make a string which is loo

String and list both are the different data type of different domain and structure of both data type is different. So when we want to convert string to list, we must aware of string as well as list in python.Example of conversion-String1='Mytext'And we want to make a list which is look like �List=
