PrettyTable's main goal is to let you print tables in an attractive ASCII form, like Settings, discussed later, are maintained. Not quite the same as creating a fresh table instance, though - style related The clear method takes no arguments and deletes all rows and all field names.Keeps the field names as they were so you that you can repopulate it with the same The clear_rows method takes no arguments and deletes all the rows in the table - but.The del_column method takes a field name of a single column to delete.The del_row method takes an integer index of a single row to delete.There are three ways to get data out of a PrettyTable, in increasing order of execute ( "SELECT field1, field2, field3 FROM my_table" ) mytable = from_db_cursor ( cursor ) Getting data out connect ( "mydb.db" ) cursor = connection. Module), then you can build a PrettyTable using a cursor object, like this: import sqlite3 from prettytable import from_db_cursor connection = sqlite3. an SQLite database accessible using the sqlite If you have your table data in a database which you can access using a library whichĬonfirms to the Python DB-API (e.g. If you have your table data in a comma-separated values file (.csv), you can read thisĭata into a PrettyTable like this: from prettytable import from_csv with open ( "myfile.csv" ) as fp : mytable = from_csv ( fp ) Importing data from a database cursor Kind of confusing for other people to read, though, so don't do this unless you have a Some of your table in one way and some of it in the other. If you really want to, you can even mix and match add_row and add_column and build add_column ( "Annual Rainfall" ,) Mixing and matching You are adding corresponds to, and a list or tuple which contains the column data: x.
Method, which takes two arguments - a string which is the name for the field the column You can add data one column at a time as well. add_rows (, ,, ,, ,, ] ) Column by column When you have a list of rows, you can add them in one go with add_rows: x. The field_names attribute, and then add the rows one at a time using the add_row
To do this you can set the field names first using Let's suppose you have a shiny new PrettyTable: from prettytable import PrettyTable x = PrettyTable ()Īnd you want to put some data into it.
