String
Concatenation

Concepts
variables are place holders
assignment of values, data flow, goes from right to left
conditionals
loops
if/else statements
Nested structures
loops allow you to execute set of instructions multiple times
indentation tells python what instructions belong to the loop

Syntax

# assign 54 to variable x
x = 54

# Display a message
print("My name is Lily")

# Display a product 
print( 3 * 2 )

# Display the content of a variable
x = 54
print(x)

Conditionals and loops

# prompt the user for input - allows data from keyboard to your program
name = input("what is your name? ")

# prompt the user for a number
# input assigns a string value
# so it must be converted to integer for math operations or comparisons
age = int(input("What is your age? "))

# Display messages and string variables using the concatenation operator +
print("My name is " + name + " and yours? ")

# Display messages and numerical variables
print("My age is ", age, " and yours? ")
or
print("My age is " + str(age) + " and yours? ")



# checking conditions
if x > y:
   print( x," is larger than ",y)



# loops
while yesNo = "y":
   

Random Module

randNumber = random.randrange(1,8)
random.randrange([start], stop[, step])

Lists
working with lists of numbers
Printing all the items in a list:

>>> intList = [54,32,78,23,45]
>>> for i in intList:
	print(i,end=' ')

	
54 32 78 23 45 
>>> 

Adding all the items in a list

>>> intList = [54,32,78,23,45]
>>> total = 0
>>> for i in intList:
	total += i

	
>>> total
232
>>> 

or
>>> sum(intList)
232
>>> 

>>> len(intList) # number of items in the list
5
>>> import random
>>> ranList=[]
>>> ranList=[0,0,0,0,0,0,0,0,0,0,0,0,0]
>>> # assign random integers from 3 through 51 included to a list
>>> for i in range(len(ranList)):
	ranList[i]=random.randint(3,51)

>>> ranList
[43, 51, 43, 44, 37, 12, 7, 25, 32, 46, 14, 32, 20]

working with lists of strings

>>> wordList = ['red','yellow','black','green','blue']
>>> for word in wordList:
	print(word, end=' ')

	
red yellow black green blue 
>>> for word in wordList:
	print(word)

	
red
yellow
black
green
blue
>>> 

>>> for i in range(len(wordList)):
	print(i,wordList[i])

	
0 red
1 yellow
2 black
3 green
4 blue
>>> 

>>> wordList = ['red','yellow','black','green','blue']
>>> len(wordList)
5
>>> wordList[0]
'red'
>>> wordList[4]
'blue'
>>> print(random.randint(0,len(wordList)-1))
1
>>> print(random.randint(0,len(wordList)-1))
4
>>> print(random.randint(0,len(wordList)-1))
1
>>> print(random.randint(0,len(wordList)-1))
1
>>> print(random.randint(0,len(wordList)-1))
2
>>> print(random.randint(0,len(wordList)-1))
0
>>> 

# Now we can select randomly any item in the list as many times as we want
>>> print(wordList[random.randint(0,len(wordList)-1)])
red
>>>
