Question:

How can I Find the Largest Prime Value in a Dictionary of ASCII Sums?

Problem:

I'm working on a Python script that reads a text file, splits it into a list of strings, and calculates the sum of ASCII values for each string. I've stored this data in a dictionary where the strings are the keys and the ASCII sums are the values. Now, I need help finding the largest prime value from this dictionary. Any suggestions or code examples would be greatly appreciated!

if __name__ == "__main":

# Opening the file in read mode with all words in a txt file

my_file = open("english FILTERED.ALL.txt", "r")

# Reading the file

data = my_file.read()

# Replacing and splitting the text when newline ('\n') is seen.

data_into_list = data.split("\n")

print(data_into_list)

my_file.close()

# Create a dictionary to store the list values and the ASCII values with them

result_dict = {}

# Loop through the list and calculate the sum of ASCII values for each string

for x in data_into_list:

ascii_sum = sum(ord(char) for char in x)

result_dict[x] = ascii_sum

# Printing the original list

print("The original list: " + str(data_into_list))

# Printing the dictionary containing string-sum pairs

print("String and their ASCII sum: " + str(result_dict))

I have successfully calculated the sum of ASCII values for each string and stored them in a dictionary. However, I'm now trying to find the largest prime value among these sums.

Here is currently an example of my current output

String and their ASCII sum : {'ACM': 209, 'ANSI': 299, 'ASAP': 293, 'ASCII': 361, 'Achilles': 805, 'Ada': 262, 'Afghanistan': 1124, 'Africa': 582, 'African': 692, 'Africans': 807, 'Airedale': 791, 'Alabama': 671, 'Alabamian': 886, 'Alaska': 589, 'Albania': 680, 'Albanian': 790, 'Albanians': 905, 'Alcibiades': 993, 'Alden': 484, 'Algeria': 693}

I'm seeking guidance on how to efficiently identify the largest prime value from a dictionary of ASCII sums, as I want to find the largest prime ASCII sum in my dictionary.

Solution:

Is_prime function implemented to call. Iterating on the dictionary that u created, and it finds the largest prime number.

Sample Code:

def is_prime(n):

if n <= 1:

return False

if n <= 3:

return True

if n % 2 == 0 or n % 3 == 0:

return False

i = 5

while i * i <= n:

if n % i == 0 or n % (i + 2) == 0:

return False

i += 6

return True

result_dict = {'ACM': 209, 'ANSI': 299, 'ASAP': 293, 'ASCII': 361, 'Achilles': 805, 'Ada': 262, 'Afghanistan': 1124, 'Africa': 582, 'African': 692, 'Africans': 807, 'Airedale': 791, 'Alabama': 671, 'Alabamian': 886, 'Alaska': 589, 'Albania': 680, 'Albanian': 790, 'Albanians': 905, 'Alcibiades': 993, 'Alden': 484, 'Algeria': 693}

largest_prime = None

for string, ascii_sum in result_dict.items():

if is_prime(ascii_sum):

if largest_prime is None or ascii_sum > largest_prime:

largest_prime = ascii_sum

if largest_prime is not None:

largest_prime_strings = [string for string, ascii_sum in result_dict.items() if ascii_sum == largest_prime]

print("The largest prime:", largest_prime)

print("Key:", largest_prime_strings)

else:

print("No prime values")

Output:
