Python- Everything is Object

In this project, I studied object instantiation in Python, delving into variable aliasing and object identifiers, types, and mutability. The project involved a series of quiz-like questions the answers to which I provided in single-line .txt files.

Tasks

• 0. Who am I?
• 0-answer.txt: What function would you use to print the type of an object?


• 1. Where are you?
• 1-answer.txt: How do you get a variable's identifier (which is the memory address in the CPython implementation)?


• 2. Right count
• 2-answer.txt: In the following code, do a and b point to the same object?

>>> a = 89
>>> b = 100 

• 3. Right count =
• 3-answer.txt: In the following code, do a and b point to the same object?

  >>> a = 89
  >>> b = 89 

• 5. Right count =+
• 5-answer.txt: In the following code, do a and b point to the same object?

  >>> a = 89
  >>> b = a + 1  

• 6. Is equal
• 6-answer.txt: What do these 3 lines print?

>>> s1 = "Best School"
>>> s2 = s1
>>> print(s1 == s2)

• 7. Is the same
• 7-answer.txt: What do these 3 lines print?

>>> s1 = "Best"
>>> s2 = s1
>>> print(s1 is s2)

• 8. Is really equal
• 8-answer.txt: What do these 3 lines print?

>>> s1 = "Best School"
>>> s2 = "Best School"
>>> print(s1 == s2)

• 9. Is really the same
• 9-answer.txt: What do these 3 lines print?

>>> s1 = "Best School"
>>> s2 = "Best School"
>>> print(s1 is s2)

• 10. And with a list, is it equal
• 10-answer.txt: What do these 3 lines print?

>>> l1 = [1, 2, 3]
>>> l2 = [1, 2, 3]
>>> print(l1 == l2)

• 11. And with a list, is it the same
• 11-answer.txt: What do these 3 lines print?

>>> l1 = [1, 2, 3]
>>> l2 = [1, 2, 3]
>>> print(l1 is l2)

• 12. And with a list, is it really equal
• 12-answer.txt: What do these 3 lines print?

>>> l1 = [1, 2, 3]
>>> l2 = l1
>>> print(l1 == l2)

• 13. And with a list, is it really the same
• 13-answer.txt: What do these 3 lines print?

>>> l1 = [1, 2, 3]
>>> l2 = l1
>>> print(l1 is l2)

• 14. List append
• 14-answer.txt: What does this script print?

l1 = [1, 2, 3]
l2 = l1
l1.append(4)
print(l2)

• 15. List add
• 15-answer.txt: What does this script print?

l1 = [1, 2, 3]
l2 = l1
l1 = l1 + [4]
print(l2)

• 16. Integer incrementation
• 16-answer.txt: What does this script print?

def increment(n):
    n += 1
a = 1
increment(a)
print(a)

• 17. List incrementation
• 17-answer.txt: What does this script print?

def increment(n):
    n.append(4)
l = [1, 2, 3]
increment(l)
print(l)

• 18. List assignation
• 18-answer.txt: What does this script print?

def assign_value(n, v):
    n = v
l1 = [1, 2, 3]
l2 = [4, 5, 6]
assign_value(l1, l2)
print(l1)

• 19. Copy a list object
• 19-copy_list.py: Python function def copy_list(l): that returns a copy of a list.
• 20. Tuple or not?
• 20-answer.txt: Is a a tuple?

a = ()

• 21. Tuple or not?
• 21-answer.txt: Is a a tuple?

a = (1, 2)
