It is a crucial step in the data science process as real-world data is often messy and inconsistent. [](https://www.youtube.com/watch?v=jp93e9DDBlo&list=PL9XvIvvVL50Fba7psesg6ynQXdipw-yoN&index=21 "Data Wrangling") The general steps to do `Data Wrnagling` in python are as follows: >**Steps to perform data wrangling on the Titanic dataset in Python using pandas library:** >The steps of data wrangling in Python typically include: 1. Importing necessary libraries such as Pandas, NumPy, and Matplotlib 2. Loading the data into a Pandas DataFrame 3. Assessing the data for missing values, outliers, and inconsistencies 4. Cleaning the data by filling in missing values, removing outliers, and correcting errors 5. Organizing the data by creating new columns, renaming columns, sorting, and filtering the data 6. Storing the cleaned data in a format that can be used for future analysis, such as a CSV or Excel file 7. Exploring the data by creating visualizations and using descriptive statistics 8. Creating a pivot table to summarize the data 9. Checking for and handling duplicate rows 10. Encoding categorical variables 11. Removing unnecessary columns or rows 12. Merging or joining multiple datasets 13. Handling missing or null values 14. Reshaping the data 15. Formatting the data 16. Normalizing or scaling the data 17. Creating new features from existing data 18. Validating data integrity 19. Saving the final data for future use 20. Documenting the data wrangling process for reproducibility Please note that the steps may vary depending on the data, the requirements, and the goals of the analysis. It's worth noting that these are general steps and the specific steps you take will depend on the dataset you are working with and the analysis you plan to perform. ---- Here is an example of how to perform data wrangling on the `titanic` dataset in Python using the pandas library: ```python # Import the necessary libraries import pandas as pd import numpy as np import matplotlib.pyplot as plt import seaborn as sns # Load the Titanic dataset into a pandas DataFrame titanic = sns.load_dataset('titanic') # View the first few rows of the dataset titanic.head() # View the column names and data types titanic.info() # Check for missing values print(data.isnull().sum()) # Handle missing values # Option 1: Drop rows with missing values titanic.dropna(inplace=True) # Option 2: Impute missing values titanic['Age'].fillna(titanic['Age'].mean(), inplace=True) # Check for outliers and remove or transform them as necessary sns.boxplot(x=titanic['age']) # Transform outliers titanic['Age'] = np.log(titanic['Age']) # Feature engineering titanic['family_size'] = titanic['sibsp'] + titanic['parch'] + 1 titanic['is_alone'] = 1 # initialize to yes/1 is alone titanic['is_alone'].loc[titanic['family_size'] > 1] = 0 # now update to no/0 if family size is greater than 1 # Group and aggregate data data = titanic.groupby('Pclass').mean() # Save the cleaned dataset titanic.to_csv('titanic_cleaned.csv', index=False) ``` This is just one example of how to perform data wrangling on the Titanic dataset, but there are many other ways you can handle missing values, outliers, and feature engineering. The important thing is to understand the data, and to make decisions based on the context of the problem you're trying to solve. Another way of treating the data is as follows: ```python # Import the necessary libraries import pandas as pd import numpy as np import matplotlib.pyplot as plt import seaborn as sns # Load the Titanic dataset data = pd.read_csv('titanic.csv') # View the first few rows of the dataset print(data.head()) # Check for missing values print(data.isnull().sum()) # Handle missing values data['age'].fillna(data['age'].median(), inplace=True) data['embarked'].fillna(data['embarked'].mode()[0], inplace=True) # Check for outliers # Option 1: Remove outliers q1 = data["fare"].quantile(0.25) q3 = data["fare"].quantile(0.75) iqr = q3-q1 fence_low = q1-1.5*iqr fence_high = q3+1.5*iqr data = data[(data["fare"] > fence_low) & (data["fare"] < fence_high)] # Option 2: Transform outliers data['fare'] = data['fare'].apply(lambda x: x if x < 100 else 100) # Feature engineering #if the titles are given in the dataset data['Title'] = data.Name.str.extract(' ([A-Za-z]+)\.', expand=False) data['Title'] = data['Title'].replace(['Lady', 'Countess','Capt', 'Col','Don', 'Dr', 'Major', 'Rev', 'Sir', 'Jonkheer', 'Dona'], 'Rare') data['Title'] = data['Title'].replace('Mlle', 'Miss') data['Title'] = data['Title'].replace('Ms', 'Miss') data['Title'] = data['Title'].replace('Mme', 'Mrs') data = data.drop(['Name'], axis=1) data = pd.get_dummies(data, columns = ["Title"]) # Group and aggregate data data = data.groupby(['Pclass', 'Sex']).mean() # Save the cleaned dataset data.to_csv('titanic_cleaned.csv', index=True) ``` In this example I have used IQR method to check for outliers, and I have used some feature engineering techniques, like extracting title from the name and creating dummies variables and also I have grouped the data by Pclass and Sex and taken the mean of the data. It's important to note that the steps you take during data wrangling will vary depending on the dataset and the specific analysis you plan to perform. The examples above should give you an idea of the types of tasks that are typically involved in data wrangling and how to perform them using the pandas library. --- ## **Day-16** ### **Machine Learning Basics** In this lecture we will learn what is machine learning and how we can implement that in our everyday life, projects and science themes.
