Mastering pandas - Second Edition

Appending a single row to a DataFrame

We can append a single row to a DataFrame by passing a series or dictionary to the append method:

    In [152]: 
    algos={'search':['DFS','BFS','Binary Search','Linear'],
            'sorting': ['Quicksort','Mergesort','Heapsort','Bubble Sort'],
           'machine learning':['RandomForest','K Nearest Neighbor','Logistic Regression','K-Means Clustering']}
    algoDF=pd.DataFrame(algos);algoDF
    Out[152]: machine learning    search      sorting
    0    RandomForest        DFS      Quicksort
    1    K Nearest Neighbor   BFS      Mergesort
    2    Logistic Regression  Binary Search Heapsort
    3    K-Means Clustering   Linear       Bubble Sort
    
    In [154]: 
    moreAlgos={'search': 'ShortestPath'  , 'sorting': 'Insertion Sort',
                'machine learning': 'Linear Regression'}
     algoDF.append(moreAlgos,ignore_index=True) ...
