8.2.3. File Stat
Write a Python program that reads the contents of a file and
determines the number of words in the file, the number of non-blank lines in the
file, and average number of words per non-blank line. For this program a word
is defined as any group of contiguous non-blank characters separated from other
characters by whitespace. Use the frontiero_v_richardson.txt file
to test your program.
Sample Output
Ensure your program’s output matches the provided samples exactly.
This includes all characters, white space, and punctuation. In the
samples, user input is highlighted like
this for clarity, but your program should not highlight user
input in this way.
Sample Output
$ python3 file_stats_login.py
Total number of words: 1271
Total number of lines: 61
Average number of words per line: 20.8
Deliverables
Save your finished program as file_stats_login.py, replacing
login with your Purdue login. Then submit it along with all the
deliverables listed in
Table 8.6 below.
