Explanation:
The output of this program is 5 7, because the first time bruce is printed, his value is 5, and the second time, his value is 7. The comma at the end of the first print statement suppresses the newline after the output, which is why both outputs appear on the same line.
Here is what multiple assignment looks like in a state diagram:

With multiple assignment it is especially important to distinguish between an assignment operation and a statement of equality. Because Python uses the equal sign (=) for assignment, it is tempting to interpret a statement like a = b as a statement of equality. It is not!
First, equality is symmetric and assignment is not. For example, in mathematics, if a = 7 then 7 = a. But in Python, the statement a = 7 is legal and 7 = a is not.
Furthermore, in mathematics, a statement of equality is always true. If a = b now, then a will always equal b. In Python, an assignment statement can make two variables equal, but they don’t have to stay that way:
a = 5
Answer:
D. # pick up the turtle and move it to (-100,200)
Explanation:
goto() option lets the user to move to a particular location.
so, goto(-100, 200) picks up the turtle and moves to the starting location will be used to indicate location to begin writing the word.
Answer:
A loop in a computer program is an instruction that repeats until a specified condition is reached. In a loop structure, the loop asks a question. If the answer requires action, it is executed. ... A computer programmer who needs to use the same lines of code many times in a program can use a loop to save time

Answer:
1. SSH/Telnet.
2. SMTP.
3. DNS.
4. DHCP.
5. HTTPS/SSL.
6. FTP
Explanation:
1. Provides connections to computers over a TCP/IP network: the standard protocol used for this is SSH/Telnet, through port number 22 and 23 respectively.
SSH is acronym for secure shell.
2. Sends e-mail over a TCP/IP network: SMTP using port number 25.
SMTP is an acronym for Simple Mail Transfer Protocol and it uses the standard port number of 25 to provide clients with requested services.
3. Translates URLs to IP address: DNS using port number 53.
A Domain Name System (DNS) can be defined as a naming database in which internet domain names (website URLs) are stored and translated into their respective internet protocol (IP) address. This simply means that, DNS is used to connect uniform resource locator (URL) or web address with their internet protocol (IP) address.
4. Automates assignment of IP address on a network: DHCP using port number 67.
Dynamic Host Configuration Protocol (DHCP) is a standard protocol that assigns IP address to users automatically from the DHCP server.
5. Securely transports web pages over a TCP/IP network: HTTPS/SSL using port number 443.
HTTPS is acronym for Hypertext Transfer Protocol Secure while SSL is acronym for Secure Sockets Layer (SSL).
6. Transports files over a TCP/IP network: FTP using port number 20 or 21.
FTP is an acronym for file transfer protocol.
