in python, what is a database "cursor" most like?
Answers
In Python, a database "cursor" is most like a file handle. It's an interface between the database and the program. Cursors are the most fundamental database abstraction in Python because they allow developers to access database records one by one.
Cursors are used to access and retrieve information from the database. They allow a database program to execute SQL queries and retrieve rows of data. When a database query is executed, the cursor is positioned at the beginning of the result set, which can then be navigated using a series of methods such as fetchone(), fetchmany(), and fetchall() that can return either a single row or a sequence of rows. Cursors can also be used to insert, delete, or update records in the database. Cursors are created and managed by the database connection object.
It's crucial to close cursors properly once they've been used because leaving them open can cause memory leaks. In summary, a database cursor in Python is like a file handle, in that it provides access to the underlying data, but in this case, the data is stored in a database rather than in a file.

(B) Volatile memory loses its contents when there is no electricity while non-volatile memory retains its content with or without electricity. (C) Non-volatile memory loses its contents when there is no electricity while volatile memory retains its content with or without electricity. (D) None of these
Answers
The difference between Volatile and Non-Volatile Memory is that volatile memory loses its contents when there is no electricity, while non-volatile memory retains its content with or without electricity. The correct option is B.
Volatile memory is a type of computer memory that requires an electrical charge to maintain the information stored. In contrast, non-volatile memory does not require an electrical charge to store data and retains information even when power is off.Examples of volatile memory include RAM (Random Access Memory) and Cache Memory. These are used to store data temporarily while the computer is running. Once the power is turned off, the contents of volatile memory are lost.On the other hand, non-volatile memory examples include ROM (Read-Only Memory), Flash Memory, and hard drives. These are used to store data permanently and retain information even when power is off. This makes non-volatile memory an ideal choice for long-term data storage such as operating system files, media files, and documents.

So, it should look like this:
1. Centrigrade: 50 --> Kelvin: 323.15
2. Centrigrade: 51 --> Kelvin: 324.15
3. Centrigrade: 52 --> Kelvin: 325.15
etc.
Answers
Answer:
for degree in range(50, 101):
kelvin = degree + 273.15
print("Centrigrade: {} --> Kelvin: {}".format(degree, kelvin))
Explanation:
*The code is in Python.
Create a for loop that iterates from 50 to 100 (Note that the starting value is included, but the ending value is not included in the range method. That is why you need to write range(50, 101) to iterate from 50 to 100)
Convert the centigrade to kelvin using formula (Note that the degree variable represents the each centigrade degree from 50 to 100 and you need to add 273.15 to convert it to Kelvin)
Print the result as in requested format
