This program uses a for loop to print the numbers from 1 to 10. The range function is used to create a sequence of numbers from 1 to 10, which are then printed to the console.
In this code, we first load the iris dataset using the load_iris() function from scikit-learn. We then split the data into training and testing sets using the train_test_split() function. Next, we scale the features using the StandardScaler() function from scikit-learn. We then train the KNN model with n_neighbors = 3 using the KNeighborsClassifier() function. After training the model, we predict the species of the iris flowers in the testing set using the predict() function. Finally, we evaluate the performance of the model using the accuracy_score() , precision_score() , recall_score() , and f1_score() functions from scikit-learn. Note that the values of the metrics may vary slightly depending on the random seed used for splitting the dataset. # Import necessary libraries from sklearn.datasets import load_iris from sklearn.model_selection import train_test_split from sklearn.neighbors import KNeighborsClassifier from sklearn.preprocessing import StandardScaler from sklea...

We then load a dataset from a CSV file using the pd.read_csv() function from pandas . Next, we print the first 5 rows of the dataset using the head() method to get a quick glimpse of what the data looks like. We also print some summary statistics of the dataset using the describe() method to get an idea of the data's distribution. Finally, we create a scatter plot of two variables ...
