# LISTS -------------
# A list allows you to create a list of values and manipulate them
# Each value has an index with the first one starting at 0

# Insert item at given index
grocery_list.insert(1, "Pickle")

# Remove item from list
grocery_list.remove("Pickle")

# Sorts items in list

# Get length of list
print(len(to_do_list))

# Get the max item in list
print(max(to_do_list))

# Get the minimum item in list

# TUPLES -------------
# Values in a tuple can't change like lists

pi_tuple = (3, 1, 4, 1, 5, 9)

# Convert tuple into a list
new_tuple = list(pi_tuple)

# Convert a list into a tuple
# new_list = tuple(grocery_list)

# tuples also have len(tuple), min(tuple) and max(tuple)

# DICTIONARY or MAP -------------
# Made up of values with a unique key for each value
# Similar to lists, but you can't join dicts with a +

super_villains = {'Fiddler' : 'Isaac Bowin',
                  'Captain Cold' : 'Leonard Snart',

# Get the value for the passed key
print(super_villains.get("Pied Piper"))

# Get a list of dictionary keys
print(super_villains.keys())

# Get a list of dictionary values
print(super_villains.values())

# CONDITIONALS -------------
# The if, else and elif statements are used to perform different
# actions based off of conditions
# Comparison Operators : ==, !=, >, <, >=, <=

# The if statement will execute code if a condition is met
# White space is used to group blocks of code in Python
# Use the same number of proceeding spaces for blocks of code

age = 30
if age > 16 :
    print('You are old enough to drive')

# Use an if statement if you want to execute different code regardless
# of whether the condition ws met or not

if age > 16 :
    print('You are old enough to drive')
else :
    print('You are not old enough to drive')

# If you want to check for multiple conditions use elif
# If the first matches it won't check other conditions that follow

if age >= 21 :
    print('You are old enough to drive a tractor trailer')
elif age >= 16:
    print('You are old enough to drive a car')
else :
    print('You are not old enough to drive')

# You can combine conditions with logical operators
# Logical Operators : and, or, not

# FOR LOOPS -------------
# Allows you to perform an action a set number of times
# Range performs the action 10 times 0 - 9
for x in range(0, 10):
    print(x , ' ', end="")

print('\n')

# You can use for loops to cycle through a list
grocery_list = ['Juice', 'Tomatoes', 'Potatoes', 'Bananas']

for x in range(0,3):
    for y in range(0,3):
        print(num_list[x][y])

# WHILE LOOPS -------------

# times you'll have to loop
random_num = random.randrange(0,100)

        i += 1
        # Skips to the next iteration of the loop
        continue

    i += 1

# FUNCTIONS -------------
# Functions allow you to reuse and write readable code
# Type def (define), function name and parameters it receives
# return is used to return something to the caller of the function
def addNumbers(fNum, sNum):
    sumNum = fNum + sNum
    return sumNum

print(addNumbers(1, 4))

# Can't get the value of rNum because it was created in a function

newNum = 0;
def subNumbers(fNum, sNum):

    return newNum

print(subNumbers(1, 4))

# USER INPUT -------------
print('What is your name?')

# Stores everything typed up until ENTER
name = sys.stdin.readline()

print('Hello', name)

# STRINGS -------------
# A string is a series of characters surrounded by ' or "
long_string = "I'll catch you if you fall - The Floor"

# Retrieve the first 4 characters
print(long_string[0:4])

# Get the last 5 characters

# Concatenate part of a string to another
print(long_string[:4] + " be there")

# String formatting
print("%c is my %s letter and my number %d number is %.5f" % ('X', 'favorite', 1, .14))

# Capitalizes the first letter
print(long_string.capitalize())

# Returns the index of the start of the string
# case sensitive
print(long_string.find("Floor"))

# Returns true if all characters are letters ' isn't a letter
print(long_string.isalpha())

# Returns true if all characters are numbers
print(long_string.isalnum())

		<p>Derek,</p>
<p>   Where is the source code location for these tutorials?  I think I saw a link in one of the videos, but now I can’t seem to locate them.</p>
<p>   Thanks,</p>

		<p>Derek,</p>
<p>   Nevermind, I eventually found it.  I had a bug running video #8, OOP, and found when I clicked “more” on youtube, a note for the source code was listed.</p>
<p>   Thanks,</p>
<p>Michael</p>

		<p>Jeepers you are awesome. I hope you will make a video on how to manipulate postgreSQL databases with Python. I might use Django when I get some Python learned. I think pg is more intuitive to code, can’t stand to look at mysql commands. I want to make a database driven website, already know html, css, and some postgres and javascript.</p>

# A variable is a place to store values

# Its name is like a label for that value

name = "Derek"

print(name)

# A variable name can contain letters, numbers, or _

# but can't start with a number

# There are 5 data types Numbers, Strings, List, Tuple, Dictionary

# You can store any of them in the same variable

name = 15

print('\n' * 5)

# LISTS -------------

# A list allows you to create a list of values and manipulate them

# Each value has an index with the first one starting at 0

grocery_list = ['Juice', 'Tomatoes', 'Potatoes', 'Bananas']

print('The first item is', grocery_list[1])

# You can change the value stored in a list box

grocery_list[0] = "Green Juice"

print(to_do_list)

# Insert item at given index

grocery_list.insert(1, "Pickle")

# Remove item from list

grocery_list.remove("Pickle")

# Sorts items in list

# Get length of list

print(len(to_do_list))

# Get the max item in list

print(max(to_do_list))

# Get the minimum item in list

# TUPLES -------------

# Values in a tuple can't change like lists

pi_tuple = (3, 1, 4, 1, 5, 9)

# Convert tuple into a list

new_tuple = list(pi_tuple)

# Convert a list into a tuple

# new_list = tuple(grocery_list)

# tuples also have len(tuple), min(tuple) and max(tuple)

# DICTIONARY or MAP -------------

# Made up of values with a unique key for each value

# Similar to lists, but you can't join dicts with a +

super_villains = {'Fiddler' : 'Isaac Bowin',

'Captain Cold' : 'Leonard Snart',

'Weather Wizard' : 'Mark Mardon',

# Get the value for the passed key

print(super_villains.get("Pied Piper"))

# Get a list of dictionary keys

print(super_villains.keys())

# Get a list of dictionary values

print(super_villains.values())

# CONDITIONALS -------------

# The if, else and elif statements are used to perform different

# actions based off of conditions

# Comparison Operators : ==, !=, >, <, >=, <=

# The if statement will execute code if a condition is met

# White space is used to group blocks of code in Python

# Use the same number of proceeding spaces for blocks of code

age = 30

if age > 16 :

print('You are old enough to drive')

# Use an if statement if you want to execute different code regardless

# of whether the condition ws met or not

if age > 16 :

print('You are old enough to drive')

else :

print('You are not old enough to drive')

# If you want to check for multiple conditions use elif

# If the first matches it won't check other conditions that follow

if age >= 21 :

print('You are old enough to drive a tractor trailer')

elif age >= 16:

print('You are old enough to drive a car')

else :

print('You are not old enough to drive')

# You can combine conditions with logical operators

# Logical Operators : and, or, not

if ((age >= 1) and (age <= 18)):

# FOR LOOPS -------------

# Allows you to perform an action a set number of times

# Range performs the action 10 times 0 - 9

for x in range(0, 10):

print('\n')

# You can use for loops to cycle through a list

for x in range(0,3):

for y in range(0,3):

print(num_list[x][y])

# WHILE LOOPS -------------

# While loops are used when you don't know ahead of time how many

# times you'll have to loop

random_num = random.randrange(0,100)

while (random_num != 15):

print(random_num)

# Forces the loop to end all together

break

else:

# Shorthand for i = i + 1

i += 1

# Skips to the next iteration of the loop

continue

i += 1

# FUNCTIONS -------------

# Functions allow you to reuse and write readable code

# Type def (define), function name and parameters it receives

# return is used to return something to the caller of the function

def addNumbers(fNum, sNum):

sumNum = fNum + sNum

return sumNum

print(addNumbers(1, 4))

# Can't get the value of rNum because it was created in a function

# It is said to be out of scope

# If you define a variable outside of the function it works every place

newNum = 0;

def subNumbers(fNum, sNum):

newNum = fNum - sNum

return newNum

print(subNumbers(1, 4))

# USER INPUT -------------

print('What is your name?')

# Stores everything typed up until ENTER

name = sys.stdin.readline()

print('Hello', name)

# STRINGS -------------

# A string is a series of characters surrounded by ' or "

long_string = "I'll catch you if you fall - The Floor"

# Retrieve the first 4 characters

print(long_string[0:4])

# Get the last 5 characters

print(long_string[-5:])

# Everything up to the last 5 characters

print(long_string[:-5])

# Concatenate part of a string to another

print(long_string[:4] + " be there")

# String formatting

print("%c is my %s letter and my number %d number is %.5f" % ('X', 'favorite', 1, .14))

# Capitalizes the first letter

print(long_string.capitalize())

# Returns the index of the start of the string

# case sensitive

print(long_string.find("Floor"))

# Returns true if all characters are letters ' isn't a letter

print(long_string.isalpha())

# Returns true if all characters are numbers

print(long_string.isalnum())

# Returns the string length

print(len(long_string))

# Replace the first word with the second (Add a number to replace more)

print(long_string.replace("Floor", "Ground"))

# Remove white space from front and end

print(long_string.strip())

# Split a string into a list based on the delimiter you provide

quote_list = long_string.split(" ")

print(quote_list)

# FILE I/O -------------

# Overwrite or create a file for writing

test_file = open("test.txt", "wb")

# Get the file mode used

print(test_file.mode)

# Get the files name

print(test_file.name)

# Write text to a file with a newline

# Read text from the file

text_in_file = test_file.read()

print(text_in_file)

# Delete the file

os.remove("test.txt")

# CLASSES AND OBJECTS -------------

# The concept of OOP allows us to model real world things using code

# Every object has attributes (color, height, weight) which are object variables

# Every object has abilities (walk, talk, eat) which are object functions

class Animal:

# None signifies the lack of a value

# You can make a variable private by starting it with __

__name = None
