Conclusion 

1. Consider a string, tuple, and list of characters.

In []: a = 'acbde'

In []: b = ('a', 'b', 'c', 'd', 'e')

In []: c = ['a', 'b', 'c', 'd', 'e']

The values of a[3], b[3], and c[3] are all the same. In what ways are a, b, and c different? 

Strings can be printed and concatenated as a standard string.

Tuples can be appended and store different string lengths in each element.

A list of characters can only be read from.

2.  Why do computer programming languages almost always have a variety of variable types?    

Languages have different variable types because different variables' contents are incompatible by nature.

3.  Why can't everything be represented with an integer?

Technically speaking, everything COULD be represented as integers since computers store everything as 1s and 0s. But it would be difficult and inefficient.

Goals

• No More then 140 Characters
• That the following Characters were used ( ,  "  !  ?)

Code

def eligible(essay):
    a=0
    if len(essay)<=140:
        a+=1
    else:
        print ("Your essay is to long! It must be shorter than 140 characters!")
    if '?' in essay:
        a+=1
    else:
        print ("Your essay needs a question(?)!")
    if '"' in essay:
        a+=1
    else:
        print ("Your essay needs a quote("")!")
    if ', and' or ', or' or ', but' in essay:
        a+=1
    else:
        print ("Your essay needs a compound sentence(, and/, or/, but)!")
    if '!' in essay:
        a+=1
    else:
        print ("Your essay needs an exclaimation(!)!")
    if a==5:
        print ("Thank You! Your essay has been submited.")
    else:
        print ("Please fix your essay and resubmit it.")


Conclusion

1.       How many characters are in this sentence? Does it matter whether Python is storing the string as one byte per character or four bytes per character?

41 characters are in this sentence. Yes it matters, because it will take up four times more space

2.      This question asks you about something you have not learned. In fact, the question is asking about details that go beyond what you will learn in this course. However, wondering what is going on at a lower level of abstraction – and talking about it – can be a useful strategy when learning about computing.

Describe what you think occurs in memory when the following code is executed.

In []: a = 'one string'

In []: b = 'another'

In []: c = a[:3] + ' and ' + b

In []: print(c[6:10])

 a and b are saved in the code and c is defined as a[:3] + 'and' +b. When these variables are called, the code will take what is defined and use it for the variables.
