Output different precision by column with pandas.DataFrame.to_csv()?

Question

Question

Is it possible to specify a float precision specifically for each column to be printed by the Python pandas package method pandas.DataFrame.t

Answer 1

The to_string approach suggested by @mattexx looks better to me, since it doesn't modify the dataframe.

It also generalizes well when using jupyter notebooks to get pretty HTML output, via the to_html method. Here we set a new default precision of 4, and override it to get 5 digits for a particular column wider:

from IPython.display import HTML
from IPython.display import display

pd.set_option('precision', 4)

display(HTML(df.to_html(formatters={'wider': '{:,.5f}'.format})))
