I can help you with that! Here's a sample Python script that will find all the capitalized words in a given text file and present them in alphabetical order:

filename = 'example.txt'  # Replace with your file name
capitalized_words = []

with open(filename, 'r') as file:
   text = file.read()
   # Use regular expression to find all capitalized words
   capitalized_words = re.findall(r'\b[A-Z][a-z]*\b', text)

# Sort the list of capitalized words in alphabetical order
capitalized_words.sort()

# Print the list of capitalized words
print("Capitalized words in alphabetical order:")
for word in capitalized_words:
   print(word)
```
In this script, we first define the filename of the text file we want to search for capitalized words. We then initialize an empty list `capitalized_words` to store the words we find.
Next, we open the file and read its contents into a string variable `text`. We use a regular expression to search for words that start with a capital letter and are followed by zero or more lowercase letters. The `\b` in the regularexpression specifies a word boundary, so we're only matching whole words.
We then sort the list of capitalized words in alphabetical order using the `sort()` method.
Finally, we print the list of capitalized words using a `for` loop. This will output the capitalized words in alphabetical order.

To count the number of negative values in the "temperatures" list, you can use the following Python code. Sum variable is used to add all the values.

In this program we can take values of temperature in decimal values by taking the data type of temp variable as float. Array is used to enter the ten temperature values. Sum variable is used to add all the values.

count = 0
for temp in temperatures:
   if temp < 0:
       count += 1

This code initializes a counter variable "count" to 0 and then iterates over each element "temp" in the "temperatures" list. For each element, it checks if the value is less than 0 (i.e. negative) and if so, it increments the counter by 1. Once the loop is complete, the "count" variable will hold the total number of negative values in the list.
Note that this assumes that the "temperatures" list contains numeric values. If the list contains non-numeric values, the code will throw an error.
