Analyzing Project Data with pandas
When managing multiple freelance projects, you often need to analyze data such as hours worked, earnings from each project, and which clients give you the most work. The pandas library is a powerful tool that helps you organize and analyze this kind of data efficiently. With pandas, you can store your project information in a structured format and perform calculations or summaries with just a few lines of code. This makes it much easier to spot trends, track your progress, and make informed business decisions as a freelancer.
123456789101112import pandas as pd # Create a DataFrame with freelance project data data = { "Project": ["Website Redesign", "App Development", "Logo Design", "SEO Optimization", "Content Writing"], "Hours Worked": [30, 50, 10, 20, 15], "Earnings": [1500, 3000, 500, 1200, 600], "Client": ["Acme Corp", "Beta LLC", "Acme Corp", "Delta Inc", "Beta LLC"] } df = pd.DataFrame(data) print(df)
Once your data is in a pandas DataFrame, you can quickly analyze it using built-in methods. For example, you can calculate the total hours you have worked across all projects by using the sum() method on the "Hours Worked" column. To find out your average earnings per project, use the mean() method on the "Earnings" column. If you want to identify your most frequent client, the value_counts() method on the "Client" column will show you which client appears most often in your records. These methods help you gain insights into your workload, income, and client distribution with minimal effort.
