(Solved) : Q1 List Value Appears Python Program Basically Thinks Take New Sheet Paper Write Values P Q44082668 . . .
Q1
When a list value appears in a Python program, it basicallythinks “take out a new sheet of paper, and write some values onit.”
You probably have heard of, or even met, identical twins. Theylook very much alike, often dress alike, and maybe even have manyother things in common, but they are still two separate people withdifferent identities. And their being separate at least opens thepossibility of dressing differently if they feel like it.
Now, here is where things start getting interesting, especiallyto those who have prior programming experience in otherlanguages:
y = xid(y)
Group of answer choices
a) This has the same identity as x
b) SyntaxError: multiple statements found while compiling asingle statement —- if you’ve gotten this answer every singletime, you should probably go back to question 1 and read thedirections more carefully!
c) This has a different identity from x
Q2
Many other languages introduce variables as if they name boxesto put values into (each box having a different identity) and thatassigning one variable to another copies a value from one box tothe other.
Python is very different in this respect. The values themselveshave the identities, and variable names are just names given tothose values.
Probably the best analogy is to consider that many people havedifferent names. Someone named “William” might also be called”Will” or “Bill”. “Trump”, “The Donald”, and “POTUS”, at the timeof this question are all different names for the same person. (Iwon’t list other names people call him by)
The real world uses the word ‘alias’ to refer to an alternatename. Computer science also uses ‘alias’ (or ‘aliasing’) to referto this phenomenon, which is the cause of some of the hardest bugsto find, especially in C and C++ programs.
In this case, we had a little slip of paper with 4 values on it,that was previously called ‘x’, and is now called ‘y’. This has asurprising effect in some cases:
y.append(5)y.append(6)y.append(7)yx
Group of answer choices
a) X got changed by these operations!
b )Nothing seems to have happened
c) x and y are different from each other, because only ychanges
