Basic Python question?

Question

I'm using IDLE to learn Python and I'm wondering if

>>> x = 5
>>> x
5
>>> x = Hello
>>> x
Hello


If I were writing a Python program in Notepad, and I used that code in that order, does x=Hello only after I declare it, and does x = 5 only after I declare it and before I declare x = Hello

???

Thank you.

Answer 1

Yes.



That assumes that in your program you put quotes around your string Hello, so that it'll actually work. Right now you're setting x equal to the value of a variable called Hello, which you haven't defined.

Answer 2

Yes, you are correct. That is the difference between a PROCEDURAL language like Python (where each command is processed one after another) differs from a DECLARATIVE language like Html.



For each line, the program has a state. At the start, the state consists of x being undefined.

After 'x = 5', x is now 5 -- the line SETS x to be equal to 5. After 'x = Hello', x is changed to be hello.

Answer 3

because of the fact celsius you entered is a string, 3 * "a"="aaa", 3* "3"="333", convert celsius into an int via doing int(celsius), verify you assign the conversion to a variable via doing b=int(celsius) and multiply variable b via farenheit. or you're able to do: celsius=int(enter("temp in celsius")) in the 2d way you will use celsius because of the fact the variable. via the way python 3 is the main cutting-edge version, study 3 or atleast between the later variations of python 2

Answer 4

i too am sort of a noob at python but i know the answer to your question is yes

Answer 5

yep x equal what ever you set it to when you set it. So when you set it again, you overwrite the first value.
