python - 如何在Python中将单词数转换为实际单词列表

我有以下每一个单词频率的Pandas数据框：

d = {'Count' : pd.Series([2, 3, 5]), 'Term': pd.Series(['Cool', 'New', 'Very'])}
df = pd.DataFrame(d)

表格（打印df）：

  Count     Term
0   2       Cool
1   3       New
2   5       Very

但是，我想将每个单词的文字频率转换为一个名为“Term”的列中每个频率的单词列表：
输出如下：

c = {'Term': pd.Series(['Cool', 'Cool', 'New','New','New','Very', 'Very','Very','Very','Very'])}
df_2 = pd.DataFrame(c)
print df_2


        Term
0       Cool
1       Cool
2       New
3       New
4       New
5       Very
6       Very
7       Very
8       Very
9       Very

？

最佳答案

IIUC pandas repeat

df.Term.repeat(df.Count)
Out[350]:
0    Cool
0    Cool
1     New
1     New
1     New
2    Very
2    Very
2    Very
2    Very
2    Very
Name: Term, dtype: object
