# LPTHW - Exercise 7: More Printing

LPTHW - Exercise 7

This is the start of a rote copying stretch. That said, I did a few bits of my own towards the bottom of the script as you'll see below.

Having a play around with the code helps me to get a feel for the different things it does. Just trying something to see what it does is a fun way to learn.

I think as time goes by actually reading up on docs first will start to become the more efficient way to do things, but I don't think we're at that stage just yet.

Output is below as usual...

``````print("Mary had a little lamb.")
print("It's fleece was white as {}.".format('snow'))
print("And everywhere that Mary went.")
print("." * 10) # prints 10 fullstops

end1 = "C"
end2 = "h"
end3 = "e"
end4 = "e"
end5 = "s"
end6 = "e"
end7 = "B"
end8 = "u"
end9 = "r"
end10 = "g"
end11 = "e"
end12 = "r"

print(end1 + end2 + end3 + end4 + end5 + end6, end=' ')
print(end7 + end8 + end9 + end10 + end11 + end12)

print(end1 + end2 + end3 + end4 + end5 + end6, end7 + end8 + end9 + end10 + end11 + end12)

print(end1 + end2 + end3 + end4 + end5 + end6)
print(end7 + end8 + end9 + end10 + end11 + end12)

print(''.join((end1,end2,end3,end4,end5,end6)),)
print(''.join((end7,end8,end9,end10,end11,end12)) )
``````

## Learn Python The Hard Way Study Drills

### 1. Go back through and write a comment on what each line does.

``````print("Mary had a little lamb.")
print("It's fleece was white as {}.".format('snow'))
print("And everywhere that Mary went.")
print("." * 10) # prints 10 fullstops

end1 = "C"
end2 = "h"
end3 = "e"
end4 = "e"
end5 = "s"
end6 = "e"
end7 = "B"
end8 = "u"
end9 = "r"
end10 = "g"
end11 = "e"
end12 = "r"

# A comma at the end of a line here will tell the print to output the next
# printout on the same line but with a space after the last variable.
print(end1 + end2 + end3 + end4 + end5 + end6, end=' ')
print(end7 + end8 + end9 + end10 + end11 + end12)

# This can be done but code and comments aren't really supposed to go over
# 80 character width for styling reasons.
print(end1 + end2 + end3 + end4 + end5 + end6, end7 + end8 + end9 + end10 + end11 + end12)

# This is two separate lines
print(end1 + end2 + end3 + end4 + end5 + end6)
print(end7 + end8 + end9 + end10 + end11 + end12)

#This is the same line but using ''.join
print(''.join((end1,end2,end3,end4,end5,end6)),)
print(''.join((end7,end8,end9,end10,end11,end12)) )
``````

Done, except for the print lines, those are pretty much in plain English already. Well, one print line is commented because it adds `* 10` to the line, which causes the string in the print statement to be printed 10 times.

Done.

## 3. From now on, when you make mistakes, write down on a piece of paper what kind of mistake you made.

I made a mistake originally in that I didn't copy a comma in the poor formatting example (over 80 characters), but it printed on one line anyway. Reading backwards caught it.

### 4. When you go to the next exercise, look at the mistakes you have made and try not to make them in this new one.

Wouldn't that be nice!

I knew it!
