Write a program that prompts the user to enter a Social Security number in the format ddd-dd-dddd, where d is a digit. The program displays Valid SSN for a correct Social Security number or Invalid SSN otherwise.
ssn = input("Enter a valid Social Security number: ")
dashes = 0
nums = 0
message = "Invalid SSN"
if len(ssn) == 11:
for x in ssn:
if x.isdigit():
nums += 1
elif x == "-":
dashes += 1
if nums == 9 and dashes == 2:
message = "Valid SSN"
print(message)
I wrote my code in python 3.8. I hope this helps!
The program that prompts the user to enter a Social Security number in the format ddd-dd-dddd, where d is a digit can be implemented in Python using regular expressions. The regular expression pattern for the SSN format can be used to validate the input.
Pythons code:
```python
import re
ssn_pattern = re.compile(r'^\d{3}-\d{2}-\d{4}$')
ssn = input("Enter your Social Security Number (format: ddd-dd-dddd): ")
if ssn_pattern.match(ssn):
print("Valid SSN")
else:
print("Invalid SSN")
```
In the above code, we first import the `re` module to work with regular expressions.
We then define the regular expression pattern for the SSN format as `^\d{3}-\d{2}-\d{4}$`. This pattern matches any string that starts with three digits, followed by a hyphen, then two digits, another hyphen, and finally, four digits.
We then prompt the user to enter their SSN using the `input()` function. We then check if the entered SSN matches the pattern using the `match()` function of the regular expression object `ssn_pattern`.
If the SSN matches the pattern, we print "Valid SSN". Otherwise, we print "Invalid SSN".

Exercise 3.6.9: 24 vs. "24"5 points
Using the correct data type is important when math operators are involved.
Strings can also be “added” together. This is called concatenation.
A substring is part of an existing string. When strings are concatenated, each separate substring is combined to create a new string. Let’s check this out!
In this exercise, change the variables in the second code segment to strings and run the code. What do you notice?
# Code Segment One - Data Type - numbers
num_result = 24 + 24
print(num_result)
# Code Segment Two - Data Type - Strings
# Change both numbers to strings and run code
# Change only one number to a string and run code. What happens?
string_result = 24 + 24
print(string_result)
python
This is all you need to do for this one add quotes around the number to make it a string. Then for the question I don't know if you need to answer it but I said that when there is only one string it creates and addition problem of 24 + 24 and then when there are two strings it puts them right next to each other making it look like the number 2424.
The string in Python is indeed an unchangeable data type. A Unicode character is sequentially wrapped in single, double, or triple quotes. In Python, a whole number is null, negatively or positively ironclad, and has unlimited precise accuracy, such as 0, 100, -10.
Program Explanation:
In this code two-variable "num_result and string_result" is defined in which one is a string and one is an integer.In the integer and string variable, it adds two integer values with the "+" symbol.So, it will print the value that is "48" and "24 + 24".Program:
num_result = 24 + 24#defining an integer variable that use 2 integer value with "+" symbol
print(num_result)#print adding value
string_result = "24 + 24"#defining a string variable that use 2 integer value with "+" symbol
print(string_result)#print string value

Microsoft issued the Windows ME operating system. What was the impact of this 'rush to market' software product on users and Microsoft's reputation?
Answer:
The answer is below
Explanation:
Windows ME which originally meant Windows Millennium Edition. It was released in 2000. However, due to its poor functionality and efficiency, it appeared like it was rushed on the part of Microsoft to release the latest Operating System at the time. This led to some impacts on both the users and Microsoft.
1. On the Users' part: it was considered the most hated edition. Some even renamed it "Windows Mistake Edition." Users quickly dumped it for a later edition of Microsoft OS which was "Windows XP."
2. On Microsoft's part: it badly affected their reputation in the market at that period. It was the launch of Windows XP and later window 7 that revived the good reputation of Microsoft going forward.

What is while loop?A while loop is a control flow statement that enables code to be performed repeatedly based on a specified Boolean condition in the majority of computer programming languages. The while loop can be viewed as an iterative version of the if statement.
While a predetermined condition is satisfied, a while loop is a loop that repeatedly executes the code provided in its body, also known as a while statement. The loop ends if or when the condition is no longer satisfied.
We can repeat the execution of various statements using the do-while loop. When we need to run the loop at least once, the do-while loop is typically utilised.
The given program will run till the value of a will be equal to 4, so till then it will display 1, 2, and 3.
Thus, the correct option is B.

Answer:
Yes it can
Explanation:
The answer is Yes something approximating a hierarchical file system can be simulated.

what is difference between data analytics and data mining?
Answer:
Difference Between Data Mining and Data Analytics
Data mining is catering the data collection and deriving crude but essential insights. Data analytics then uses the data and crude hypothesis to build upon that and create a model based on the data. Data mining is a step in the process of data analytics.
Answer:
Data mining is an approach to finding unknown relationships in data, i.e. not attempting to confirm a specific hypothesis but looking for “interesting” relationships. A classic example is an engineer looking at a data set from a convenience store chain noticed the high correlation of men buying beer and diapers on Friday afternoons. (Despite urban legend, the store did not change anything because of it).
Data analytics is the use of statistical techniques to test hypotheses in order to improve decisions in business. Its really just a new name for things advanced companies have been doing for years. Big data is just hype to push a non-relational agenda

Answer:
Readable code is easy to understand and useful to other programmers working with the code, or C on Edge.
Explanation:
It's in the notes on edge in the "Readible Code" section
Readable code is code that is well-structured, commented, and easy to understand, making it useful to other programmers working with the code. Therefore, the correct answer is option C.
The most important part of writing readable code is making sure it is well-structured and easy to understand for other programmers. This means using consistent formatting such as clear indentations, consistent naming conventions, and including comments to explain logical operations. Additionally, making sure the code is written in a large font so that it is not too small can be helpful in improving readability. Finally, password protecting the code so only authorized programmers can access it can help prevent tampering and unauthorized modifications.
Therefore, the correct answer is option C.

Your company decided to upgrade to 10Gbps using 10GBASE-T networking. Which category of Ethernet cable would you use, to cover distance up to 100m (328ft)
Answer:
Cat 6A
Explanation:
Many networking experts agree that the Cat 6A (Category 6A) cable can offer highspeed internet access of up to 10Gbps.
Apart from the speed advantage it also has stability/scale advantages like being able to cover a maximum distance of up to 100m (328ft). However, other ethernet cables like Cat 6 are able to cover a length of just about 55 meters (180 ft) which lesser than Cat 6A. Hence, the Company should use a Cat 6A for the planned upgrade.
