Print sample set of columns from dataframe in Pandas?
提问by daniellemarie
How do you print (in the terminal) a subset of columns from a pandas dataframe?
如何打印（在终端中）来自 Pandas 数据帧的列子集？
I don't want to remove any columns from the dataframe; I just want to see a few columns in the terminal to get an idea of how the data is pulling through.
我不想从数据框中删除任何列；我只想在终端中看到几列，以了解数据是如何通过的。
Right now, I have print(df2.head(10))which prints the first 10 rows of the dataframe, but how to I choose a few columns to print? Can you choose columns by their indexed number and/or name?
现在，我可以 print(df2.head(10))打印数据框的前 10 行，但是如何选择要打印的几列？您可以按索引号和/或名称选择列吗？
回答by RagingRoosevelt
print(df2[['col1', 'col2', 'col3']].head(10))will select the top 10 rows from columns 'col1', 'col2', and 'col3'from the dataframe without modifying the dataframe.
print(df2[['col1', 'col2', 'col3']].head(10))将选择的前10行从列'col1'，'col2'以及'col3'从数据帧，而无需修改数据帧。
