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 more current version of hknust's first line would be:

df_data['vals'] = df_data['vals'].map(lambda x: '{0:.1}'.format(x))

To print without scientific notation:

df_data['vals'] = df_data['vals'].map(lambda x: '{0:.1f}'.format(x))
