Hi, i am using ActivePython 2.7.2.5, and windows 8 professional.
well the original ex3.py is:
print "I will now count my chickens:"
print "Hens", 25 + 30 / 6
print "Roosters", 100 - 25 * 3 % 4
print "Now I will count the eggs:"
print 3 + 2 + 1 - 5 + 4 % 2 - 1 / 4 + 6
print "Is it true that 3 + 2 < 5 - 7?"
print 3 + 2 < 5 - 7
print "What is 3 + 2?", 3 + 2
print "What is 5 - 7?", 5 - 7
print "Oh, that's why it's False."
print "How about some more."
print "Is it greater?", 5 > -2
print "Is it greater or equal?", 5 >= -2
print "Is it less or equal?", 5 <= -2
And i have made ex3.py this way below
print "I will now count my chickens:"
print "Hens",25+30.0/6
print "Roosters",100 - 25.0 * 3.0 % 4
print "Now I will count the eggs:"
print 3+2+1-5.0+4.0%2-1/4.0+6
print "Is it true that 3+2<5-7?"
print 3+2<5-7
print "What is 3+2?",3+2
print "What is 5-7?",5-7
print "Oh, that's why it's False."
print "How about some more."
print "Is it greater?", 5>-2
print "Is it greater or equal?", 5>=-2
print "Is it less or equal?", 5<=-2
The author has given us extra credit to practice so here it is and the
5th point below, which i was asking.
Extra Credit
1. Above each line, use the # to write a comment to yourself explaining
what the line does.
2. Remember in Exercise 0 when you started python? Start python this way
again and using the above characters
and what you know, use python as a calculator.
3. Find something you need to calculate and write a new .py file that
does it.
4. Notice the math seems "wrong"? There are no fractions, only whole
numbers. Find out why by researching
what a "floating point" number is.
5. Rewrite ex3.py to use floating point numbers so it's more accurate
(hint: 20.0 is floating point).
