What is it called when you assign a value to a variable?
The first time a variable is assigned a value, it is said to be initialised. The = symbol is known as the assignment operator. It is also possible to declare a variable and assign it a value in the same line, so instead of int i and then i = 9 you can write int i = 9 all in one go.
What does it mean to assign a value to a variable give an example?
Assigning a value to a variable means storing a value to a variable. The second line stores the number 55 to our variable age. If you want, you could also combine those two lines into one, as : age = 55; In this one line above, we declare a variable called age when we assign the value 55.
What happens when you assign the value of one variable to another?
Earlier on, cheese was assigned to point to the same object as spam pointed to, which happened to be 42 at that time. Since you have not modified cheese, it still points to 42. Immutability has nothing to do with it in this case, since pointer assignment does not change anything about the object being pointed to.
When do you assign values to a variable in Python?
Now when you assign values to a variable, Python actually assigns references which are pointers to memory locations allocated to objects: Now when you assign objects of different type to the same variable, you actually change the reference so that it points to a different object (i.e. different memory location).
What happens when you add a NUM to a variable?
When we have a = num, nothing is being copied, but now both variables refer to the same object and a is added to the same namespace. This is where my book, Automate the boring stuff with Python, confuses me.
How to create a different variable in Python?
If you want different variable use slice operator: (Assignment statements in Python do not copy objects, they create bindings between a target and an object.). The problem you’re running into is that s1=s doesn’t copy.
