Saving data to csv

[asifsultan-THD]

I was following your first video to store the data in the csv file. I am not able to read the csv file. I imported pandas and then trying to go open but it was showing me this error
"UnicodeDecodeError: 'utf-8' codec can't decode byte 0x80 in position 0: invalid start byte"

If you are using pandas, you could read csv by simply doing

import pandas as pd
data = pd.read_csv(filename, encoding= 'unicode_escape')

The default behaviour of save_data is to create a pickle file. You need to pass the to_format parameter to save_data.

For example

solution.save_data("filename.csv", ["Time [s]", "Terminal voltage [V]"], to_format="csv")
