📊 Common Programming Tasks
💻 Example: Basic Python Program
The following example demonstrates basic Python syntax using variables, functions, and output.
basic_python.py
def greet(name):
return f"Welcome, {name}!"
student = "Machine Learning"
print(greet(student))💻 Example: Loading a Dataset
Pandas simplifies loading and inspecting structured datasets.
load_dataset.py
import pandas as pd
data = pd.read_csv("students.csv")
print(data.head())
print(data.shape)💻 Example: Training a Machine Learning Model
The following example trains a Decision Tree classifier using scikit-learn.
train_model.py
from sklearn.tree import DecisionTreeClassifier
X = [[1], [2], [3], [4]]
y = ["Low", "Low", "High", "High"]
model = DecisionTreeClassifier(random_state=42)
model.fit(X, y)
prediction = model.predict([[3]])
print("Prediction:", prediction[0])📦 Saving and Loading Models
Trained models can be saved and reused without retraining.
save_and_load_model.py
from joblib import dump, load
from sklearn.tree import DecisionTreeClassifier
model = DecisionTreeClassifier()
model.fit([[1], [2]], ["A", "B"])
dump(model, "model.joblib")
loaded_model = load("model.joblib")
print(loaded_model.predict([[2]]))🌍 Real-World Programming Applications
