Description
In this homework, you will be writing a short program in Python to find duplicate words in a file.
This assignment focuses on Chapter 5, specifically reading data from a file.
Program(Features(
A common mistake when writing is duplicating a word (“the the”). This is a big enough problem
that Microsoft Word and other text editing software will mark these mistakes as errors. In this
assignment, we will develop a short Python program that will find these duplicate words and alert
the user by printing out a simple message. I suggest using a for loop to read the file data line by line.
Once you have a line you will need to perform further string manipulations to determine if there s a
duplicate word.
Given the following (slightly mangled) text stored inside of quote.txt:
He that would make his own liberty liberty secure,
must guard even his enemy from oppression;
for for if he violates this duty, he
he establishes a precedent that will reach to himself.
— Thomas Paine
Running your program would produce the following output (user input is green):
Enter file name: quote.txt
Found word: “liberty” on line 1.
Found word: “for” on line 3.
Found word: “he” on line 4.
As shown above, your program should also be able to find duplicate words across(lines in the input
file.
Helpful(Hints(
We haven t gotten to lists yet, but we can make use of one for this assignment without knowing all
the details. Here s an example of how to get all of the words in a line and turn them into separate
strings:
line = “This is a line from a file”
words = line.split() # We saw split() in Chapter 4. It will break up
# our string into just the words (no whitespace)
# and maintain the order. So the variable words
# contains “This”, “is”, “a” “line”, “from”,
# “a”, and “file”.
# To access those individual words (separate strings) use a for loop:
for word in words:
print(word)
Each iteration of the for loop will print out a word. The variable word becomes “This”, then “is”
and so on, until all of the words have been printed. The result of the loop is shown below:
This
is
a
line
from
a
file
