(if you're not working in a virtualenv, you may need to do this with sudo.)

Synopsis:

See the docstrings in textgrid.py

Example:

This is a simple example of reading a TextGrid file.

import textgrid

# Read a TextGrid object from a file.
tg = textgrid.TextGrid.fromFile('test.TextGrid')

# Read a IntervalTier object.
print("------- IntervalTier Example -------")
print(tg[0])
print(tg[0][0])
print(tg[0][0].minTime)
print(tg[0][0].maxTime)
print(tg[0][0].mark)

# Read a PointTier object.
print("------- PointTier Example -------")
print(tg[1])
print(tg[1][0])
print(tg[1][0].time)
print(tg[1][0].mark)

The content of the file test.TextGrid is as below:

File type = "ooTextFile"
Object class = "TextGrid"

xmin = 0
xmax = 1
tiers? <exists>
size = 2
item []:
    item [1]:
        class = "IntervalTier"
        name = "words"
        xmin = 0
        xmax = 1
        intervals: size = 2
        intervals [1]:
            xmin = 0
            xmax = 0.5
            text = """Is anyone home?"""
        intervals [2]:
            xmin = 0.5
            xmax = 1
            text = "asked ""Pat"""
    item [2]:
        class = "TextTier"
        name = "points"
        xmin = 0
        xmax = 1
        points: size = 2
        points [1]:
            number = 0.25
            mark = """event"""
        points [2]:
            number = 0.75
            mark = """event"" with quotes again"

The following is the output of the above snippet:

------- IntervalTier Example -------
<IntervalTier words, 2 intervals>
Interval(0.0, 0.5, "Is anyone home?")
0.0
0.5
"Is anyone home?"
------- PointTier Example -------
<PointTier points, 2 points>
Point(0.25, "event")
0.25
"event"
