Hello John. Some good process here. Rember you can assign number values to a variable - along with what you have done with strings already. Here's an example:



In [57]:

    
numb = 5
highnum = 15
print 5 + 15

There are many python modules that are not loaded by default. We can tell the program what to open by using the import command. random is a module worth getting to know.



In [58]:

    
import random



In [60]:

    
randnum = random.randint(0,20)

This will give you a random number between 0 and 20



In [63]:

    
print randnum

You should check out lists next - they are a great way of holding a bunch of data together. You can make something a list by using [ ]. Here's we go:



In [42]:

    
newlist = []
print newlist

[]

This makes a new empty list called newlist. There is nothing in it, but we can add to it with append



In [46]:

    
newlist.append(message)
print newlist









    



['John Thompson \tWas called the worst computer programmer at the place', 'John Thompson \tWas called the worst computer programmer at the place']

Lists are good because you can edit them. Another way of holding data is a tuple. These are made with ()



In [54]:

    
newtuple = ('hello', 'john', 'this is not a list')



In [55]:

    
print newtuple









    



('hello', 'john', 'this is not a list')



In [56]:

    
newtuple.count('hello')









    Out[56]:





1

Tuples can not be changed unlike lists.

print("This is a long line of text that has been \nedited with the new line command. \t\nThe tab command has been used as a further editing \nexercize")

print("mary had a pair of shoes that did not fit her")

Heading one



In [19]:

    
def addnum(mynumber):
    return mynumber + 5



In [21]:

    
addnum(-15)









    Out[21]:





-10



In [28]:

    
addnum(+35)









    Out[28]:





40

using markdown willgive auto notes.. Using heading gives pretty fonts format and compose by Simple function is def addnum(mynumber):then return mynumber (choose n+-) no multiply or division



In [31]:

    
print(type(3+7))
print(5*8)
print(type("Here is a written text"))









    



<type 'int'>
40
<type 'str'>



In [32]:

    
a = 3+5
b = a * a - a - 1
c = a * b
print(c)



In [36]:

    
a =3+5
b = a * a - a - 1
c = a * b
if (a>0):
    print(c)
else:
    print (c-a)

LISTS Remember the list begins at zero and you can change inividual values



In [37]:

    
a= [1, -7, 0, 0, 5, 10]
a [3]= "no number"
print a









    



[1, -7, 0, 'no number', 5, 10]



In [38]:

    
a [2]= 19
print a









    



[1, -7, 19, 'no number', 5, 10]
