What is the difference between showing and selecting. I assume when I select something it can be manipulated, but I may be wrong. I.e. SHOW columns FROM customers vs. SELECT * FROM customers. Is there a difference?

>>>a=10
>>>while a<=25:
a+=2
print(a)
>>>12,......26
Why this code print up to 26 when it is less than 25?
>>>a = 10
>>>while a <= 25:
print(a)
a+=2
>>>12,.......24
What is the difference between these two code & why they give different result?

I have an iphone 5s and when I test the code, I see no difference from thick and 700. I also wrote:
CSS:
.p thickest {
Font-size: 900;
}
Html:
<p .thickest>This should be "BOLDEST"
</p>
And the last 3 were the same size. Could it be the phone or is the code wrong?

If except can handle common errors very well, doesn't that make the use of raise redundant inside of a try-except block?
For example:
try:
print( 5 / 0 )
except ZeroDivisionError:
raise ValueError("An error occurred!")
What's the difference if we handle it this way:
try:
print( 5 / 0 )
except (ZeroDivisionError, ValueError):
print("An error occurred!")

The basic difference between Id and class it that, an ID can be applied to only single type of elements no matter how many times you apply or how many ids you create
but in slight edge class is same as id but can be applied to different types of elements
