gtabview 0.9

Stand-alone usage

gtabview reads most text tabular data formats automatically:

gtabview data.csv
gtabview data.txt

If xlrd is installed, Excel files can be read directly:

gtabview file.xls[x]

Usage as a module

gtabview.view() can be used to display simple Python types directly in tabulated form:

from gtabview import view

# view a file
view("/path/to/file")

# view a list
view([1, 2, 3])

# view a dict (by columns)
view({'a': [1, 2, 3], 'b': [4, 5, 6], 'c': [7, 8, 9]})

# view a dict (by rows)
view({'a': [1, 2, 3], 'b': [4, 5, 6], 'c': [7, 8, 9]}, transpose=True)

# view a simple list of lists
view([[1, 2, 3], [4, 5, 6], [7, 8, 9]])

# view a simple list of lists (with headers)
view([['a', 'b', 'c'], [1, 2, 3], [4, 5, 6], [7, 8, 9]], hdr_rows=1)

gtabview includes native support for NumPy and all features of Pandas’ DataFrames, such as MultiIndexes and level names:

from gtabview import view

# numpy arrays up to two dimensions are supported
import numpy as np
view(np.array([[1, 2, 3], [4, 5, 6]]))

# view a DataFrame/Series/Panel
import pandas as pd
df = pd.DataFrame([[1, 2, 3], [4, 5, 6]],
                  columns=['a', 'b', 'c'], index=['x', 'y'])
view(df)

gtabview is designed to integrate correctly with matplotlib. If you’re using gtabview with matplotlib either directly or indirectly (for example, using the Pandas visualization API or Seaborn), be sure to include matplotlib first to correctly initialize gtabview.

gtabview will also use matplotlib’s interactive setting to determine the default behavior of the data window: when interactive, calls to view() will not block, and will keep recycling the same window.

To use gtabview in a Python Notebook with inline graphics, you’ll probably want to force the detached behavior. In the first cell of your notebook, initialize both gtabview and matplotlib as follows:

import gtabview
gtabview.DETACH = True
from gtabview import view
%matplotlib inline

When using view, a separate data window will show. The window can be kept around or closed, but will only be refreshed when evaluating the cell again. Jupyter is currently known not to work properly (https://github.com/TabViewer/gtabview/issues/32).

Requirements and installation

gtabview is available directly on the Python Package Index.

gtabview requires:

• Python 3 or Python 2

• PyQt5, PyQt4 or PySide

• setuptools (install-only)

Under Debian/Ubuntu, install the required dependencies with:

sudo apt-get install python3 python3-pyqt5
sudo apt-get install python3-setuptools

Then download and install simply via pip:

pip install gtabview

Install xlrd if direct reading of Excel files is desired:

pip install xlrd
