<SYSTEM_TASK:>
Given the following text description, write Python code to implement the functionality described below step by step
<END_TASK>
<USER_TASK:>
Description:
 Segment (pyannote.core.segment.Segment)
Step1:  Segment instances are used to describe temporal fragments (e.g. of an audio file).
Step2:  Segment instances are nothing more than 2-tuples augmented with several useful methods and properties.
Step3:  Intersection
Step4:  Inclusion
Step5:  Other operations
Step6:  SlidingWindow (pyannote.core.segment.SlidingWindow)
Step7:  Iteration
Step8:  Cropping
Given an interval, .crop can be used to return every position of the sliding window within this interval.
Step9:  strict mode only returns fully contained positions.
Step10:  loose mode returns any intersecting position.
Step11:  center mode centers first and last position on interval boundaries.
Step12:  Need help?
You can always try the following...
Who knows? It might give you the information you are looking for!

Python Code:
from pyannote.core import Segment
Explanation: Segment (pyannote.core.segment.Segment)
End of explanation
# start time in seconds
s = 1.
# end time in seconds
e = 9.
segment = Segment(start=s, end=e)
segment
Explanation: Segment instances are used to describe temporal fragments (e.g. of an audio file).
End of explanation
start, end = segment
print 'from %f to %f' % (start, end)
print 'Segment %s ends at %g seconds.' % (segment, segment.end)
print 'Its duration is %g seconds.' % (segment.duration)
print 'Its middle stands as %g seconds.' % (segment.middle)
Explanation: Segment instances are nothing more than 2-tuples augmented with several useful methods and properties.
End of explanation
other_segment = Segment(4, 13)
if segment.intersects(other_segment):
    print 'Segment %s intersects other segment %s.' % (segment, other_segment)
    intersection = segment & other_segment
    print 'Their intersection is %s.' % (str(intersection))
notebook.crop = Segment(0, 15)
segment
other_segment
segment & other_segment
other_segment = Segment(13, 20)
if not (segment & other_segment):
    print 'Those two segments do not intersect.'
notebook.crop = Segment(0, 30)
segment
other_segment
Explanation: Intersection
End of explanation
other_segment = Segment(5, 6)
if other_segment in segment:
    print '%s in included in %s' % (other_segment, segment)
t = 23.
if not segment.overlaps(t):
    print '%s does not contain time %f' % (segment, t)
Explanation: Inclusion
End of explanation
other_segment = Segment(10, 30)
print 'Union of %s and %s is %s' % (segment, other_segment, segment | other_segment)
other_segment = Segment(14, 15)
print 'Gap between %s and %s is %s' % (segment, other_segment, segment ^ other_segment)
Explanation: Other operations
End of explanation
from pyannote.core import SlidingWindow, Timeline
Explanation: SlidingWindow (pyannote.core.segment.SlidingWindow)
End of explanation
notebook.crop = Segment(0, 10)
window = SlidingWindow(start=0.0, step=1.1, duration=2., end=10.)
Timeline(window)
Explanation: Iteration
End of explanation
interval = Segment(3., 7.5)
interval
Explanation: Cropping
Given an interval, .crop can be used to return every position of the sliding window within this interval.
End of explanation
indices = window.crop(interval, mode='strict')
Timeline(window[i] for i in indices)
Explanation: strict mode only returns fully contained positions.
End of explanation
indices = window.crop(interval, mode='loose')
Timeline(window[i] for i in indices)
Explanation: loose mode returns any intersecting position.
End of explanation
indices = window.crop(interval, mode='center')
Timeline(window[i] for i in indices)
Explanation: center mode centers first and last position on interval boundaries.
