How is the usage of df.to_csv in Python?
The method df.to_csv() is used on a DataFrame object to save the data frame as a CSV file. Its syntax is:
df.to_csv('filename.csv', sep=',', index=False)
The ‘filename.csv’ is the name of the file to be saved, the sep parameter indicates the delimiter used in the CSV file, which is comma (,) by default, and the index parameter indicates whether to save the row index to the file, which is True by default. The parameters can be adjusted as needed to save the CSV file.
