Suppressing scientific notation in pandas?

Suppressing scientific notation in pandas?

You can suppress scientific notation in pandas by setting the display options for float formatting. You can do this using the pd.options.display.float_format attribute or the pd.set_option() function. Here's how to suppress scientific notation:

import pandas as pd # Sample DataFrame data = {'value': [12345.6789, 0.00012345, 123.45]} df = pd.DataFrame(data) # Set the display option to suppress scientific notation pd.options.display.float_format = '{:.2f}'.format # Alternatively, you can use pd.set_option() # pd.set_option('display.float_format', '{:.2f}'.format) # Display the DataFrame print(df)

In this example, we set the display option pd.options.display.float_format to format floating-point numbers with two decimal places ('{:.2f}'.format). You can adjust the number of decimal places as needed.

Now, when you display the DataFrame df, the numbers will be formatted without scientific notation:

 value 0 12345.68 1 0.00 2 123.45

This formatting will be applied to all floating-point numbers in your DataFrame. If you have multiple DataFrames and want to apply the formatting to all of them, you can set the option once at the beginning of your script or notebook.
