This code goes throught the "tweet" and if one thing is not included then it will not go through the code, but instead will stop and tell you if you arte missing something.
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?
There are forty one characters in that sentence and it does not matter if because it is recognizing how many characters not bites.

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])
First it stores 'one string' into a, 'another' into b, and a[:3] + 'and' + b. c would then equal "one and another". then c[6:10] is printed. That would be "d an".
