In Python, a list stores a collection of different pieces of information as a sequence under a single variable name.
For example: grocery_list = [“Milk”, “Eggs”, “Rice”,

Now we need to get input from the user. We can do it like this:

Write an if statement that checks to see if the string is not empty.
If the string is not empty, print the user's word.
Otherwise (else), print "empty" if the string is empty.

"""
Pig Latin only works with words, so we need to check if the user
typed in a word or something like 238asdf23819.
Thankfully, Python can check for this using the isalpha() function.
Modify your if statement to look like this and test it out:
if len(original) > 0 and original.isalpha():
Make sure you SAVE, RUN and test it out before moving on.
"""
# Exercise 4: Adding the "ay"
"""
Write the following code BEFORE your if statement:
Create a variable named pyg and set it equal 'ay'.
Convert what's stored in the variable 'original' to
all lowercase letters and store it as the variable 'word'
Create a new variable called "first" and set it to the first letter of
the variable "word"
"""
# Exercise 5: Checking for Vowels
'''
If the user's word starts with a vowel (a,e,i,o,u), you just add "ay" to the end
For example, "apple" becomes "appleay"
If the user's word starts with anything else, you move the first letter of the word
to the end and add "ay"
For example, "banana" becomes "ananabay"
Let's check to see if the users word starts with a vowel.
Add a new if/else block nested inside of your existing one.
The new if should check to see if the first letter of word is a vowel.
If it is, your code should print "vowel".
If the first letter of word is not a vowel,
your code should print "consonant".
You can remove the "print original" line from your code.
'''
THE CLASS STOPPED THIS LESSON TO LESSON 6
# Exercise 6: appleay!
'''
Now it's time to translate a little bit.
If the word typed by the user is a vowel, translating is easy!
Create a variable called 'new_word' that contains the result of
appending "ay" to the end of the word.
Remember you created a pyg variable that stores the "ay" string
Replace the "print 'vowel'" text and print the 'new_word' variable instead
'''
# Exercise 7: ogday!
'''
Inside the else part of your if/else block that checks the first letter of the word,
set the new_word variable equal to the translation result for a word that starts with a consonant.
Remember, you want to take the whole word (without the first letter) and append the first letter
to the end, and then append "ay" to the end of that.
Create a variable called rest and set it to the rest of the word (without the first letter)
To get the whole word without the first letter, you can slice it using the pattern s[i:j].
For example, if s = "foo", then s[1] gives you "oo"
Replace the print 'consonant' bit with print new_word. Make sure to test your code
with a word that starts with a consonant!
'''
# Exercise 8: Testing, testing!

Make sure you test your program several times and use different kinds of input.
You never know what people will type, so try lots of things (numbers, letters, symbols)
to make sure that it works properly!

and will translate them into Pig Latin
"""
# Exercise 0 : Welcome!
"""
Write a print statement that says "Welcome to the English to Pig Latin translator!"
"""
print "Welcome to the English to Pig Latin translator!"
# Exercise 1 : User Input
"""
Now we need to get input from the user. We can do it like this:
var = raw_input("Insert message here...")
Create your own user input statement.
Instead of "var", name your variable "original"
and make the message say "Please input an English word: "
"""
original = raw_input ("Please input an English word: ")
print original
# Exercise 2 : Check the input
"""
Write an if statement that checks to see if the string is not empty.
If the string is not empty, print the user's word.
Otherwise (else), print "empty" if the string is empty.
HINT: You can check to see if the string is empty by getting its length
For example, len("HELLO") is 5
len("") is 0
When you think you've got it, SAVE and RUN your program and test it out!
"""
pyg = "ay"
if len(original) > 0 and original.isalpha():
word = original.lower()
first = word[0]
if first == "a" or first == "e" or first == "i" or first == "o" or first == "u":
print "vowel"
else:
print "consonant"
else:
print "empty"
# Exercise 3: More checking
"""
Pig Latin only works with words, so we need to check if the user
typed in a word or something like 238asdf23819.
Thankfully, Python can check for this using the isalpha() function.
Modify your if statement to look like this and test it out:
if len(original) > 0 and original.isalpha():
Make sure you SAVE, RUN and test it out before moving on.
"""
# Exercise 4: Adding the "ay"
"""
Write the following code BEFORE your if statement:
Create a variable named pyg and set it equal 'ay'.
Convert what's stored in the variable 'original' to
all lowercase letters and store it as the variable 'word'
Create a new variable called "first" and set it to the first letter of
the variable "word"
"""
# Exercise 5: Checking for Vowels
'''
If the user's word starts with a vowel (a,e,i,o,u), you just add "ay" to the end
For example, "apple" becomes "appleay"
If the user's word starts with anything else, you move the first letter of the word
to the end and add "ay"
For example, "banana" becomes "ananabay"
Let's check to see if the users word starts with a vowel.
Add a new if/else block nested inside of your existing one.
The new if should check to see if the first letter of word is a vowel.
If it is, your code should print "vowel".
If the first letter of word is not a vowel,
your code should print "consonant".
You can remove the "print original" line from your code.
'''
THE CLASS STOPPED THIS LESSON TO LESSON 6
# Exercise 6: appleay!
'''
Now it's time to translate a little bit.
If the word typed by the user is a vowel, translating is easy!
Create a variable called 'new_word' that contains the result of
appending "ay" to the end of the word.
Remember you created a pyg variable that stores the "ay" string
Replace the "print 'vowel'" text and print the 'new_word' variable instead
'''
# Exercise 7: ogday!
'''
Inside the else part of your if/else block that checks the first letter of the word,
set the new_word variable equal to the translation result for a word that starts with a consonant.
Remember, you want to take the whole word (without the first letter) and append the first letter
to the end, and then append "ay" to the end of that.
Create a variable called rest and set it to the rest of the word (without the first letter)
To get the whole word without the first letter, you can slice it using the pattern s[i:j].
For example, if s = "foo", then s[1] gives you "oo"
Replace the print 'consonant' bit with print new_word. Make sure to test your code

Monday, May 20, 2013
I am very glade to be part of this python class for today, May 20th, 2013.
I learned a lot today, below arethe details:
Instructor Zane Cocchran started up with our last class lesson 2 Tip Calculator and went up to the math Operators wherein I learned how to add, subtract, multiply, divide, exponants and modules.
- I also learned String methods in this methods are pre-built pieces of code that the program used
- make certain tasks easier
- and they are quick to used.
- len() this has to do with numbers
- lower() this hasto do with small letter joseph
- upper()this has to do with capital letter JOSEPH
- str() this hasto do with age 34yrs
Also learned about Advanced Printing
Advanced Printing
e String Formatting
dessert_1 = cake
dessert_2 = cookies
print ”I like %s and %s" %
(dessert_1 , dessert_2 )
⇒ “I like cake and cookies”
These are examples of what I learned onthis day (20-05-2013) below.

Lesson 2 : Tip Calculator

We're going to create a tip calculator for when we eat at a restaraunt.
This will help us determine what our final bill is after we eat.

What did learn about today?
In my second day of lesson in this python class, I learned a lot about the following below:
In my second day of lesson in this python class, I learned a lot about the following below:
- Variables & Data type -
- Variables is the one of the most common concepts of programming,
- Data Types is in four faces in that there is
- Integer (Int): These are whole number and Negative or positive. Example 26, -56
- Floating points (float) These are numbers with Desmond number. Example 1.34
- Boolean These are true or false value. Example Liberian
- String these are words and this is the only data type that goes. with cotation. Example "Hello"
- Whitespace & Statements
- White space does matters in programming.
- Comments- in commits, there were two things that i learned in that you can start a simple commits with hatch # and in double commits you can used single or double codes
- What kinds of programs did you write?
- They are as below:
- GCC 4.6.3] on linux2
