1What is the difference between a variable declared with = and a constant in Python?
What is the difference between a variable declared with = and a constant in Python?
คำตอบ
Python does not have true constants at the language level. By convention, UPPERCASE variables are considered constants and should not be modified, but nothing technically prevents reassignment. This PEP 8 convention relies on developer discipline rather than language enforcement.
2What data type does the expression 3 / 2 return in Python 3?
What data type does the expression 3 / 2 return in Python 3?
คำตอบ
In Python 3, the / operator always performs floating-point division, returning 1.5 in this case. To get integer division, use the // operator. This is a major difference from Python 2 where / performed integer division between two integers.

What is the difference between a list and a tuple in Python?
