# obspy.core.stream.Stream.print_gaps

`Stream.``print_gaps`(min_gap=None, max_gap=None)

  Print gap/overlap list summary information of the Stream object.

  Parameters: | min_gap All gaps smaller than this value will be omitted. The value is assumed to be in seconds. Defaults to None. max_gap All gaps larger than this value will be omitted. The value is assumed to be in seconds. Defaults to None.

  Example

  Our example stream has no gaps:

      >>> from obspy import read, UTCDateTime
      >>> st = read()
      >>> st.get_gaps()
      []
      >>> st.print_gaps()
      Source            Last Sample                 Next Sample ...
      Total: 0 gap(s) and 0 overlap(s)

  So let’s make a copy of the first trace and cut both so that we end up with a gappy stream:

      >>> tr = st[0].copy()
      >>> t = UTCDateTime("2009-08-24T00:20:13.0")
      >>> st[0].trim(endtime=t)
      <...Trace object at 0x...>
      >>> tr.trim(starttime=t+1)
      <...Trace object at 0x...>
      >>> st.append(tr)
      <...Stream object at 0x...>
      >>> st.get_gaps()
      [[..., UTCDateTime(2009, 8, 24, 0, 20, 13), ...
      >>> st.print_gaps()
      Source            Last Sample                 ...
      BW.RJOB..EHZ      2009-08-24T00:20:13.000000Z ...
      Total: 1 gap(s) and 0 overlap(s)

  And finally let us create some overlapping traces:

      >>> st = read()
      >>> tr = st[0].copy()
      >>> t = UTCDateTime("2009-08-24T00:20:13.0")
      >>> st[0].trim(endtime=t)
      <...Trace object at 0x...>
      >>> tr.trim(starttime=t-1)
      <...Trace object at 0x...>
      >>> st.append(tr)
      <...Stream object at 0x...>
      >>> st.get_gaps()
      [[...'EHZ', UTCDateTime(2009, 8, 24, 0, 20, 13), ...
      >>> st.print_gaps()
      Source            Last Sample                 ...
      BW.RJOB..EHZ      2009-08-24T00:20:13.000000Z ...
      Total: 0 gap(s) and 1 overlap(s)
