1. Assignment:
Modify the Python program by adding the create_dictionary function. The parameter file_name
is the name of the csv file that contains several lines of ASCII encodings. The format of this file
is described in the link above. The function should return a dictionary where the keys are
characters and the values are the 8 bit representations. Note: use the characters for comma, quote,
and space characters, instead of the words comma, quote, and space.
Add the translate function. The parameter sentence consists of a number of characters. The
parameter dictionary is the dictionary returned by the create_dictionary function. The parameter
file_name is the name of the output file where all output should be sent. In the output file, the
text should be a binary string (zeros and ones only) with each 8 bit ascii code appearing one after
the other. (see sample transcripts)
If a character does not appear in the dictionary, the string "nUNDEFINEDn" should appear
instead of an 8 bit representation.
When the program is run, it should produce the following three output files: output-1.txt, output-
2.txt and output-3.txt.
Grading:
2 points - The create_dictionary function returns a dictionary that contains the correct binary
code for each character of length one.
1 point - The create_dictionary function returns a dictionary that contains the correct binary code
for comma, quote, and space.
3 points - When your program is tested with different values for the variable sentence, all
characters that exist in the dictionary are translated correctly.
1 point - When your program is tested with different values for the variable sentence, characters
that do NOT exist in the dictionary are translated correctly to the word UNDEFINED on a line of
its own.
1 point - The format of any output files created match the format of the sample output files
exactly. def create_dictionary(f): # f is the filename; rename the parameter as you wish pass #
open the file for reading and assign to a file handle variable* # make a dictionary variable -- it
can be empty to start with # use the file handle variable step through each line doing this.." #
make the line into a list, splitting it up at the commas # optional: temporarily try printing it out.
What you expected? # assign the binary number to a variable as a string # optional: temporarily
try printing it out. What you expected? # assign the character to a variable as a string #
optional: temporarily try printing it out. What you expected? # use the two new variables to add
an entry to the dictionary # optional: temporarily try printing it out. What you expected? #
Note: you will want the comma, space, and quote mark keys to be those actual characters.". #
