With just a few lines of code, you can clean, transform, filter, and aggregate datasets\u2014making it a favorite among data scientists and analysts.<\/p>\n<p>To get started, install pandas with <code>pip install pandas<\/code> and import it as <code>import pandas as pd<\/code>. You can create a DataFrame from a dictionary, a list of lists, or load external files like CSV using <code>pd.read_csv()<\/code>. Once your data is in a DataFrame, the real fun begins.<\/p>\n<p><img decoding=\"async\" src=\"https:\/\/sumberlaba.com\/wp-content\/uploads\/2026\/08\/article-1786903327434.jpg\" alt=\"Article illustration\" style=\"display:block;margin:20px auto;max-width:100%;height:auto;border-radius:8px;\" \/><\/p>\n<h2>Selecting and Filtering Data<\/h2>\n<p>Use label-based <code>.loc[]<\/code> and integer-based <code>.iloc[]<\/code> to access rows and columns. For example, <code>df.loc[df['age'] > 30, ['name', 'age']]<\/code> filters rows where age exceeds 30 and selects only name and age columns. Common techniques include:<\/p>\n<ul>\n<li><code>df['column']<\/code> \u2013 select a single column<\/li>\n<li><code>df[['col1', 'col2']]<\/code> \u2013 select multiple columns<\/li>\n<li><code>df[df['price'] > 100]<\/code> \u2013 filter rows by condition<\/li>\n<\/ul>\n<h2>Handling Missing Values<\/h2>\n<p>Real-world data is messy. Use <code>isna()<\/code> and <code>dropna()<\/code> to identify or remove missing entries, and <code>fillna()<\/code> to replace them\u2014for instance, <code>df['column'].fillna(df['column'].mean())<\/code> substitutes missing values with the column mean.<\/p>\n<h2>Grouping and Aggregating<\/h2>\n<p>The <code>groupby()<\/code> method splits your data into groups and applies aggregate functions. For example, <code>df.groupby('category')['sales'].sum()<\/code> returns total sales per category. You can combine multiple operations with <code>.agg(['sum', 'mean', 'count'])<\/code> for richer insights.<\/p>\n<h2>Combining Multiple DataFrames<\/h2>\n<p>Merge datasets using <code>pd.merge()<\/code> for SQL-style joins or <code>pd.concat()<\/code> for simple stacking along rows or columns. Set the <code>on<\/code> parameter to define the key column, or use <code>left_on<\/code> and <code>right_on<\/code> when column names differ.<\/p>\n<h3>Quick Recap<\/h3>\n<p>Pandas makes data manipulation fast and efficient. Master these core operations\u2014filtering, cleaning, grouping, and merging\u2014and you&#8217;ll be ready to tackle most real-world data tasks.
