Create two separate lists, a = [1, 2] and b = [1, 2]. Print their equality comparison and identity comparison.

Starter Code

a = [1, 2]
b = [1, 2]
# Print equality and identity checks

Expected Output:True False

Write a program that attempts to convert the string "hello" to an integer. If conversion fails, print "Invalid integer".

Starter Code

text = "hello"
# Attempt the conversion and handle the expected error

Expected Output:Invalid integer

Create variables count = 7, ratio = 2.5, label = "ready", and active = True. Print the type of each value on its own line.

Starter Code

count = 7
ratio = 2.5
label = "ready"
active = True

# Print each value type

Expected Output:<class 'int'> <class 'float'> <class 'str'> <class 'bool'>

Without running the code, predict the output. Then run it and explain why int(6.8) produces the displayed result.

Starter Code

value = 6.8
print(int(value))
print(type(value))

Expected Output:6 <class 'float'>

Given profile = {"name": "Asha", "active": True}, print whether "name" is a key and whether "Asha" is a value.

Starter Code

profile = {"name": "Asha", "active": True}
# Check the key and the value

Expected Output:True True

Given a = 5 and b = 8, swap their values using Python multiple assignment. Print both values on one line separated by a space.

Starter Code

a = 5
b = 8
# Swap values
# Print a and b

Expected Output:8 5
