Write a shell (text-based) program, called first_word.py, that opens the file stuff.txt and prints out the first word of every l
postnew [5]

Answer:

See explaination

Explanation:

Please check below for the code for first_word.py file which will print first word of an input file stuff.txt. So the open function will open file in read mode. We had maintained a count variable so that we can skip printing first word of first line. Also the command line.strip() checks whether string is empty or not so that we will not get index error while calling split function over line to get first word.

#!/usr/local/bin/python

stuff = open("stuff.txt", "r");

count = 0;

for line in stuff:

count+=1;

if (count>1 and line.strip()):

print(line.split(maxsplit=1)[0])

The Synonyms submenu offers a list of synonyms for a word. Is it always a good idea to use whatever synonyms are presented on th
Ann [662]

Answer:

No

Explanation:

Synonyms are sometimes NEARLY the same. Not exactly the same. Therefore the meanings can change a bit. For example a synonym for "bad" is "careless."

"I think corn is bad."

and

"I think corn is careless." - this sentence wouldn't make sense.

That's why, no, you shouldn't ALWAYS use the synonym.
