BeautifulTable
(maxwidth=80, default_alignment=ALIGN_CENTER, default_padding=1, precision=3, serialno=False, serialno_header='SN', detect_numerics=True, sign=SM_MINUS, **kwargs)[source]¶ Utility Class to print data in tabular format to terminal.
Parameters: - maxwidth (int, optional) – maximum width of the table in number of characters. this is ignored when manually setting the width of the columns. if this value is too low with respect to the number of columns and width of padding, the resulting table may override it(default 80).
- default_alignment (int, optional) – Default alignment for new columns(default beautifultable.ALIGN_CENTER).
- default_padding (int, optional) – Default width of the left and right padding for new columns(default 1).
- precision (int, optional) – All float values will have maximum number of digits after the decimal, capped by this value(Default 3).
- serialno (bool, optional) – If true, a column will be rendered with serial numbers(DEPRECATED).
- serialno_header (str, optional) – The header of the serial number column if rendered(DEPRECATED).
- detect_numerics (bool, optional) – Whether numeric strings should be automatically detected(Default True).
- sign (SignMode, optional) – Parameter to control how signs in numeric data are displayed. (default beautifultable.SM_MINUS).
-

BTColumnCollection
(table, default_alignment, default_padding)[source]¶ -
padding
¶ Set width for left and rigth padding of the columns of the table.
-
header
¶ get/set headings for the columns of the table.
It can be any iterable with all members an instance of str or None.
-
alignment
¶ get/set alignment of the columns of the table.
It can be any iterable containing only the following:
- beautifultable.ALIGN_LEFT
- beautifultable.ALIGN_CENTER
- beautifultable.ALIGN_RIGHT
-
width
¶ get/set width for the columns of the table.
Width of the column specifies the max number of characters a column can contain. Larger characters are handled according to width_exceed_policy. This can be one of ‘auto’, a non-negative integer or an iterable of the same length as the number of columns. If set to anything other than ‘auto’, the user is responsible for updating it if new columns are added or existing ones are updated.
-

Left Width of the padding specifies the number of characters on the left of a column reserved for padding. By Default It is 1.
-
padding_right

Right Width of the padding specifies the number of characters on the rigth of a column reserved for padding. By default It is 1.
-
width_exceed_policy
¶ Attribute to control how exceeding column width should be handled.
It can be one of the following:
Option Meaning beautifulbable.WEP_WRAP An item is wrapped so every line fits within it’s column width. beautifultable.WEP_STRIP An item is stripped to fit in it’s column. beautifultable.WEP_ELLIPSIS An item is stripped to fit in it’s column and appended with …(Ellipsis).
-
default_alignment

-
separator
¶ Character used to draw the line seperating two columns.
-
pop
(index=-1)[source]¶ Remove and return column at index (default last).

Raises: - TypeError: – If index is not an instance of int, or str.
- IndexError: – If Table is empty.
-
update
(key, value)[source]¶ Update a column named header in the table.
If length of column is smaller than number of rows, lets say k, only the first k values in the column is updated.
Parameters: Raises: - TypeError: – If length of column is shorter than number of rows.
- ValueError: – If no column exists with heading header.
-
insert
(index, column, header=None, padding_left=None, padding_right=None, alignment=None)[source]¶ Insert a column before index in the table.
If length of column is bigger than number of rows, lets say k, only the first k values of column is considered. If column is shorter than ‘k’, ValueError is raised.
Note that Table remains in consistent state even if column is too short. Any changes made by this method is rolled back before raising the exception.
Parameters: - index (int) – List index rules apply.
