添加重复单词的值并将其绘制出来

Question

word                  
steam               84
heating              9
horizontal well      4
electromagnetic      2
single well          1
steam                5
foam                 2
heating              1
solvent              5
hexane               7
steam foam           1
surfactant         106
miscible             1

我如何唯一地打印输出，以使重复单词的值相加而单词不重复

steam               89
foam                 2
heating             10
horizontal well      4
solvent              5
hexane               7
electromagnetic      2
steam foam           1
surfactant         106
single well          1
miscible             1

Answer 1

设置

s = pd.Series(
    [84, 9, 4, 2, 1, 5, 2, 1, 5, 7, 1, 106, 1],
    ['steam',
     'heating',
     'horizontal well',
     'electromagnetic',
     'single well',
     'steam',
     'foam',
     'heating',
     'solvent',
     'hexane',
     'steam foam',
     'surfactant',
     'miscible']
).rename_axis('word')
