Working with CsvManager
This class is intended for writing and retrieving information from CSV files.
The CsvManager class accepts three arguments:
-
newline — the newline character (default is an empty string).
-
encoding — the encoding of the files being opened (UTF-8).
-
delimiter — the delimiter used in the CSV file (;).
from ipars import CsvManager
c = CsvManager(newline="", encoding="UTF-8", delimiter=";")
Brief Overview of CsvManager Methods
-
The writerow method writes a row to a CSV file. This method accepts the file path, the write mode, and a list of data to be written in the row.
-
The writerows method accepts the same arguments as writerow, except row must be a double list with data for writing. The difference between these methods is that writerow writes one row, while writerows writes as many rows as there are in the double list.
-
The getRows method is used to obtain a list of rows from the CSV file. This method accepts the file path from which the rows will be retrieved.
-
The pprint method is the same as that of Pars.
Example Usage of CsvManager
from ipars import CsvManager
c = CsvManager()
nameFile = 'data.csv'
# Writing headers
c.writerow(nameFile, 'w', ['Quantity', 'Price', 'Total'])
# Writing data
c.writerows(nameFile, 'a', [
["5", "5", "25"],
["6", "6", "36"],
["7", "7", "49"],
])
# Retrieving rows from the table
rows = c.getRows(nameFile)
# Displaying the rows of the table
c.pprint(rows)
