hi everybody,
            I have a file:
A_16_P21360207   304
A_14_P136880    783
A_16_P21360209    795
A_16_P21360210    173
A_16_P03641959    1177
A_16_P03641960    1944
A_16_P03641962    999
A_16_P03641963    3391
A_16_P41563649    3626
A_16_P03641964    180
A_16_P41563655    1216
A_16_P03641965    1170
A_16_P03641966    194
A_16_P21360229    290
 my script:
import math
values_lis = []
fh = open('test5','r')
for line in fh.readlines():
        data = line.strip().split('\t')
        probe = data[0].strip()
        values= data[1].strip()
        value  = values[0].strip()
        value =float(values)
        old = 0
        if value >=old:
                old = value
                print '%s\t%s'%(probe,old)
   I am aiming to remove the lowest values in the second column by iterating
one over the other....say for example 304 , is lesser than the

second row value  783 so i omit the first column first value.. in the same
case in the third row 795  is greater the 783 so i omit the 783the second
row... this to be carried out for attaining my destination... i have written
the sript but it doesnot not remove the lesser values...can you please chek
where i go wrong...
