What is the difference between a module and a package in Python?

In the first example, we are going to explore the concept of a module in Python. A module is a file containing Python code that can define functions, classes, and variables. It allows you to organize your code into reusable components. Here is an example code snippet demonstrating the use of a module in Python: 
# Create a module named mymodule.py
# Define a function inside the module
def greet(name):
    return "Hello, " + name

In the code above, we have created a module named mymodule.py that defines a function called greet . This function takes a name as an argument and returns a greeting message. To use this module in another Python script, we can import it using the import keyword. 
import mymodule

message = mymodule.greet("Alice")
print(message)

When we run the above code, it will import the mymodule module and use the greet function to print a greeting message for the name "Alice". In the second example, we are going to discuss the concept of a package in Python. A package is a way of organizing related modules into a single directory hierarchy. It helps in structuring large Python projects and avoids naming conflicts between modules. Here is an example code snippet demonstrating the use of a package in Python: 
# Create a package named mypackage
# Inside the package, create two modules: module1.py and module2.py
# Define functions inside each module

# module1.py
def add(a, b):
    return a + b

# module2.py
def multiply(a, b):
    return a * b

In the code above, we have created a package named mypackage that contains two modules: module1.py and module2.py . Each module defines a function that performs a specific operation. To use these modules in another Python script, we can import them using the dot notation. 
from mypackage import module1, module2

result1 = module1.add(3, 4)
result2 = module2.multiply(2, 5)

print(result1)
print(result2)

When we run the above code, it will import the module1 and module2 modules from the mypackage package and use the functions defined in each module to perform addition and multiplication operations.

What are the different evaluation metrics used in machine learning?

In the first example, we are going to demonstrate how to use accuracy as an evaluation metric in machine learning using Python. Here is the code: from sklearn.metrics import accuracy_score y_true = [0, 1, 1, 0, 1] y_pred = [0, 1, 0, 0, 1] accuracy = accuracy_score(y_true, y_pred) print("Accuracy:", accuracy) Step 1: Import the accuracy_score function from sklearn.metrics. Step 2: Define two lists, y_true and y_pred, containing the true and predicted values. Step 3: Calculate the accuracy score by calling the accuracy_score function with y_true and y_pred as arguments. Step 4: Print out the accuracy score. In the second example, we are going to demonstrate how to use precision and recall as evaluation metrics in machine learning using Python. Here is the code: from sklearn.metrics import precision_score, recall_score y_true = [0, 1, 1, 0, 1] y_pred = [0, 1, 0, 0, 1] precision = precision_score(y_true, y_pred) recall = recall_score(y_true, y_pred) print("Precis...
