The code works in changing the shapes in the chart to what word u input. My question is how is that chart built up or if i wish to build same in my web page or blog, how do i do it?
Can somebody explain this code:
my_number = 847595593392818109495
my_number * 2
my_number / 4
*** I would assume this is the code for block 1, 2, and 3? What is the = 8475--------, *2, and /4?
This is a new question, not a reply to a previous comment.
When writing variables in code, do they always have to have the underscore in the middle? In this lesson, they give the long number the variable name of my_number. Do you always have to write variable names like that? I’m a bit confused as to why it is written like that and notjust without the underscore, ie: mynumber?
The use of snake-case is very common in Python, with the chief aim to make variable names more readable. The underscore is not needed, but we can see the difference it makes when the names are rather verbose.
I’m REALLY starting at the beginning so will be asking lot of dummy questions. On Basics of Programming p.2 - the difference that I see is that I’m only typing in in each variable once instead of three times like I did in on the previous page - is that right?
yes, that is why the lesson is called reusing variable, for example:
one = 'grass'
two = 'rocks'
three = 'forest'
now i would just do:
draw(one) // draws grass
draw(two) // draws rocks
draw(three) // draws forest
draw(one) // draws grass
draw(two) // draws rocks
draw(three) // draws forest
draw(one) // draws grass
draw(two) // draws rocks
draw(three) // draws forest
and i get 9 fields like in the example, i reuse the grasslands (and the other ones as well)
and then i only need to change 'grass' to to 'rocks' in one place to change 3 fields
Variable at the very basics of learning to program. We can store data in a variable, so we can programmatically access this value later. We don’t replace the number with a variable, we store the number in the variable.
