When the work is doneif you wanna make your work also fun: use Python!
######Exercise 2: Comments And Pound Characters
a, How do I comment out multiple lines?
[Put a # in front of each one.]
######Exercise 3: Numbers And Math
######Exercise 4: Variables And Names
a, What is the difference between = (single-equal) and == (double-equal)?
[The = (single-equal) assigns the value on the right to a variable on the left. The == (double-equal) tests if two things have the same value]
######Exercise 5: More Variables And Printing (embedded a variable in the string)
a, print "He's got %s eyes and %s hair." % (my_eyes, my_hair) ==> multiple format
b, %r is a very useful one. It's like saying "print this no matter what."
######Exercise 6: Strings And Text
######Exercise 7: More Printing (watch the comman at the end)
print end1 + end2 + end3 + end4 + end5 + end6,
print end7 + end8 + end9 + end10 + end11 + end12
######Exercise 8: Printing, Printing
formatter = "%r %r %r %r"
print formatter % (1, 2, 3, 4)
print formatter % ("one", "two", "three", "four")
######Exercise 9: Printing, Printing, Printing
######Exercise 10: What Was That?
a, This use of the \ (backslash) character is a way we can put Difficult-To-Type characters into a string.

\" Double-quote (")
\a ASCII bell (BEL)
\b ASCII backspace (BS)
\f ASCII formfeed (FF)
\n ASCII linefeed (LF)
\N{name} Character named name in the Unicode database (Unicode only)
\r ASCII Carriage Return (CR)

\v ASCII vertical tab (VT)

######Exercise 13: Parameters, Unpacking, Variables
a, [Remember that an important skill is paying attention to details.] <=================
b, code:
---from sys import argv
---script, first, second, third = argv ==>Easier way
