python - 将 Pandas 中的一列转换为一个长字符串 (Python 3)

Question

如何将 pandas 列转换为一个长字符串？

例如，转换以下DF:

Keyword
James
Went
To
The
Market

读作

Keyword
James went to the market

有什么帮助吗？

Answer 1

您可以先使用.tolist 将列转换为列表，然后使用.join 方法将所有单独的单词连接在一起。

print(df)

  Keyword
0   James
1    Went
2      To
3     The
4  Market

' '.join(df['Keyword'].tolist())

# output: 'James Went To The Market'

# or to put them in a dataframe with 1 row 1 column
pd.DataFrame(' '.join(df['Keyword'].tolist()), columns=['Keyword'], index=[0])

                    Keyword
0  James Went To The Market
