### Working with CsvManager
|
|
|
|
This class is designed to write and extract information from csv files
|
|
|
|
The CsvManager class takes three arguments: the newline character newline (default is an empty string), the encoding of the opened files encoding (default is UTF-8), and the delimiter used in the CSV file delimiter (default is ";").
|
|
|
|
```py
|
|
|
|
from ipars import CsvManager
|
|
|
|
c = CsvManager()
|
|
```
|
|
|
|
### Brief Overview of CsvManager Methods
|
|
|
|
1. The **writerow** method writes a row to the CSV file. The method takes the path to the CSV file, the write mode, and a list of data that will be written to the file's row.
|
|
|
|
2. The **writerows** method takes the same arguments as writerow, but the 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 as there are in the double list.
|
|
|
|
3. The **getRows** method is used to retrieve a list of rows in the CSV file. The method takes the path to the file from which the rows will be obtained.
|
|
|
|
4. The **pprint** method is the same as that of Pars.
|

### Example of Using CsvManager
|
|
|
|
```py
|
|
from ipars import CsvManager
|
|
c = CsvManager()
|
|
|
|
# writing headers
|
|
writer = c.writerow('./data.csv', 'w', ['Quantity', 'Price', 'Total'])
|
|
|
|
# writing data
|
|
writer = c.writerows('./data.csv', 'a', [
|
|
["5", "5", "25"],
|
|
["6", "6", "36"],
|
|
["7", "7", "49"],
|
|
])
|
|
|
|
# retrieving rows from the table
|
|
rows = c.getRows('./data.csv')
|
|
|
|
# printing table rows
|
|
c.pprint(rows)
|
|
```
