Writing a program in Python that reads a text file and organizes
the words in the file into a list without repeating words and in
all lowercase.
Here is what I have
#This program takes a user input file name and returns each word
in a list
#and how many different words are in the program.
while True: #While loop to loop program
words = 0

Program Behavior
Each time your program is run, it will prompt the user to enter
the name of an input file to analyze. It will then read and analyze
the contents of the input file, then print the results.
Here is a sample run of the program. User input is shown in
red.
Let's analyze some text!
Enter file name: sample.txt
Number of lines: 21
Number of words: 184
Number of long words: 49
Number of sentences: 14

JAVA PROGRAMMING: Write a program called TimeSymbolTables that
creates three symbol tables, each of a different implementation.
Each symbol table will contain as a key a word read from a text
file and as a value the number of times that word occurs in the
text file. Have the program fill the first symbol table with these
counts, keeping track of how long that takes using a Stopwatch
object. It then does the same thing with the second symbol table....

I am working on exercise 5.30 from Introduction to Computing
using python (Author: Perkovic).
I was looking at the solution and was able to understand what to
do. However, when I implement the temp function as indicated, I
keep getting this error "ValueError: the first two maketrans
arguments must have equal length". However, it seems my two
arguments are equal length, so I'm not sure what I am doing
wrong!
