Problem parsing the input

[Harish K Vishwanath]

Consider the code below :

x = """
... *****
... - Burst_Length not read from ini file
... ?      -
... + BurstLength not read from ini file
... *****
... - PilotTracking_Timing not read from ini file
... ? ^^^^^^^^^^^^^^
... + NumTimings not read from ini file
... - Burst Position = 89511samples
... + Analysis Time (Iterations = 1) = 0.562249s
... +  Rising Edge Time = 371683us
... -  Rising Edge Time = 371682us
... """
>>> x
'\n*****\n- Burst_Length not read from ini file\n?      -\n+ BurstLength not
read from ini file\n*****\n- PilotTracking_Timing not read from ini file\n?
^^^^^^^^^^^^^^\n+ NumTimings not read from ini file\n- Burst Position =
89511samples\n+ Analysis Time (Iterations = 1) = 0.562249s\n+  Rising Edge
Time = 371683us\n-  Rising Edge Time = 371682us\n'
>>> import re
*>>> num = re.compile('(?P<num>[0-9]+)[^.]')
>>> flt = re.compile('(?P<flt>[0-9]*\.[0-9]*)')
*>>> flt.findall(x)
['0.562249']
>>> num.findall(x)
['89511', '1', '562249', '371683', '371682']


Those regular expressions can fetch the required input.
