CSV is a flexible data format that can be easily opened and edited with both text editors and spreadsheet software. Below, I will write a simple example, with the code as follows:
# Example code to create CSV files
After running the code, there are three CSV files in the current directory: data_list.csv, data_list0.csv, and data_dict.csv. We will open them respectively.
Contents of data_dict.csv
Contents of data_list.csv
Of course, we can also read and output using csv.reader(f) in Python. This usage is similar to reading text files; we just change with open(“data_dict.csv”, “w”, newline=””, encoding=”utf-8-sig”) as f: from w to r. It is similar to the readlines() method for text operations. With this, processing JSON data becomes much easier, making it a powerful tool for web data scraping.
