Fixing Floating Point Errors in Pandas DataFrames: A Step-by-Step Guide
The issue here is that the float values in your DataFrame are being interpreted as strings, not numbers. This is because the commas in the string representations of these floats are still present. To fix this, you can use the pd.options.display.float_format option to format the floats with no commas: import pandas as pd # assume df is your DataFrame pd.options.display.float_format = '{:.1f}'.format df.columns = [col.replace(',', '') for col in df.columns] Alternatively, you can also use the str.
