What does the following code output?
python
from math import ceil
number = 4.2
result = ceil(number)
print(result)
5
Identify the error in the following code:
python
import random
number = random.randit(1, 10)
print(number)
The function randint is misspelled as randit. It should be corrected to randint.
What does the following code output?
python
from math import pi
print(pi)
3.141592653589793
Identify the error in the following code:
python
from math import log
number = -5
result = log(number)
print(result)
The math.log() function will raise a ValueError because it is being called with a negative number, which is not allowed for natural logarithms.
What does the following code output?
python
from math import pow
result = pow(2, 3)
print(result)
8.0
Identify the error in the following code:
python
import statistics
data = [1, 2, '3', 4, 5]
result = statistics.mean(data)
print(result)
The statistics.mean() function will raise a TypeError because the list data contains a string element ('3') while it expects numerical values.
What does the following code output?
python
from random import random
print(random())
A pseudo-random floating point number between 0.0 and 1.0.
Identify the error in the following code:
python
from math import factorial
number = 5.5
result = factorial(number)
print(result)
The math.factorial() function will raise a ValueError because it only accepts non-negative integer arguments, not floats.
What does the following code output?
python
from math import floor
number = 5.9
result = floor(number)
print(result)
5
Identify the error in the following code:
python
from math import exp
number = 'ten'
result = exp(number)
print(result)
The math.exp() function will raise a TypeError because it expects a numerical argument, not a string.
How is the random library applied in real-world scenarios?
Generating random numbers for simulations, games, cryptography, and statistical sampling.
How is data abstraction applied in real-world scenarios?
Operating systems hide complex hardware interactions, providing a simplified user interface.
How are control structures applied in real-world scenarios?
Traffic light systems use selection (if/else) to control traffic flow based on sensor data.
How are APIs applied in real-world scenarios?
Social media platforms provide APIs for developers to integrate their applications with the platform's data and functionality.
How is cybersecurity applied in real-world scenarios?
Banks use encryption and multi-factor authentication to protect customer data and prevent unauthorized access to accounts.
How is data representation applied in real-world scenarios?
Images are represented as arrays of pixel values to be displayed on screens.
How is algorithm design applied in real-world scenarios?
Search engines use complex algorithms to rank web pages based on relevance and other factors.
How is the math library applied in real-world scenarios?
Engineering simulations use mathematical functions to model physical phenomena.
How is the concept of the digital divide relevant in education?
Students without access to computers and the internet at home may face disadvantages in completing assignments and accessing online resources.
How are data structures applied in real-world scenarios?
Social networks use graph data structures to represent relationships between users.
What is a module?
A pre-written block of code containing functions and procedures that can be imported into a program.
What is a software library?
A collection of pre-built procedures and functions that perform specific tasks, saving development time and effort.
What is an API?
Application Program Interface. A set of rules and specifications that define how software components should interact, providing instructions on how to use a library's procedures.
What is data abstraction?
Hiding complex implementation details and exposing only essential information to the user, simplifying interaction with complex systems.
What is the digital divide?
The unequal access to technology and the internet based on socioeconomic factors, geography, or other demographic variables.
What is cybersecurity?
The practice of protecting computer systems and networks from unauthorized access, theft, damage, or disruption.
What is an integer data type?
A data type that represents whole numbers without any fractional or decimal parts.
What is a float data type?
A data type that represents numbers with fractional or decimal parts.
What is a string data type?
A data type that represents a sequence of characters, typically used to store text.
What is a boolean data type?
A data type that represents logical values, either true or false.
