Code to copy:

#Take the input file name

filename=input('Enter the input file name: ')

#Open the input file

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]));
