English algorithm explanation

Write a program that asks the user for the name of a file in the current directory. Then, open the
file and process the content of the file.
1)If the file contains words that appear more than once, print “We found duplicates.”
2)If the file does not contain duplicate words, print “There are no duplicates.”

Answer 1

Code:

fi=open("duplicate.txt","r")
#Here we open the file in read mode
data=fi.read()
#Here we read the data from the file
words=data.split()
#Here we convert the data into the list
if(len(words)!=len(set(words))):
#Here we find the lenght of the list
#and compare it with the length of the set of same list
#Set removes all duplicate elements of the list
#If boath the lenghts are not equal then duplictes are present
print("We found duplicates")
else:
# if boath the lengths are equal Duplicates are not present
print("There are no duplicates")
