A file concordance tracks the unique words in a file and their frequencies. Write a program that displays a concordance for a file. The program should output the unique words and their frequencies in alphabetical order. Variations are to track sequences of two words and their frequencies, or n words and their frequencies.

Below is an example file along with the program input and output:

example.txt

I AM SAM I AM SAM SAM I AM

inputFile = open(filename,"r+")

#Define the dictionary.

list={}

#Read and split the file using for loop

for word in inputFile.read().split():

#Check the word to be or not in file.

if word not in list:

list[word] = 1

#increment by 1

else:

list[word] += 1

#Close the file.

inputFile.close();

#print a line

print();

#The word are sorted as per their ASCII value.

fori in sorted(list):

#print the unique words and their

#frequencies in alphabetical order.

print("{0} {1} ".format(i, list[i]));
