#Frequent Words Problem (1A in book, pg. 7)

#Find the most frequent words in a string.
#Input: A string TEXT and an integer k. -- will be supplied as text file with TEXT on one line; k on next line
#Output: All most frequent k-mers in TEXT.

##Use argparse to read a file specified on the command line


#Associate contents of text file with variable - open the file


##Read in information from textfile
#Get text string from first line of file into variable text, strip newline

#Get value for k from second line of file into variable num, strip newline, assign to k


##Find all kmers and build a dictionary of kmers

    #move through text by each position from 0 to end of text less the value of k (length of kmer) e.g., for index in range(index_0,index_lenghtoftext-k)
    #define each kmer by getting substring of text from i to i+k

    
##Identify which kmers occur most often in text by looking at number of times each kmer seen in dictionary
#initialize highest total seen to 0


##Loop through kmer dictionary to find largest number of times a kmer was seen
#OR
##Get all values of kmer dictionary, sort list of values, grab highest total


##With most frequent total identified, go back through dictionary to get kmers with total matching highest total observed
#define the result variable as null

#loop through each kmer in the dictionary, obtaining value (times seen) and compare to current highest value seen

##Print list of most frequently occurring kmers
