Hi Alan
Thanks for replying,
Yes, I am having some challanges .
this is the example file :
so there are 2 dm (dm-30 and dm-31) wich 3 sample value
dm-30 1.47 36.48 2.82 0.66 270.84 148.56
240.96 0.06 44.99 18.27 6.36
dm-31 1.47 36.49 2.82 0.66 270.85 148.58
240.94 0.06 45.03 18.28 6.37
dm-30 0.00 0.00 0.00 0.00 0.00 0.00
0.00 0.00 0.00 2.00 1.00
dm-31 0.00 0.00 0.00 0.00 0.00 0.00
0.00 0.00 0.00 3.00 1.50
dm-30 0.00 0.00 0.00 0.00 0.00 0.00
0.00 0.00 0.00 0.40 0.50
dm-31 0.00 0.00 0.00 0.00 0.00 0.00
0.00 0.00 0.00 0.70 0.60
Basically I am interested with 10 and 11 ( last 2 column) with bellow 2 way
a) ignore the firsrt value for each dm ( so line number 1 and 2 will
totally ignore) : I am having trouble to do that
b) get the max value for clumn 10 and 11 for each dm (dm-30 and dm-31) : I
am having to do that
I went through this far : -
from operator import itemgetter
def _get_io():
with open (DM,'r')as f:
content=f.readlines()
return content
s_value= dict()
u_value=dict()
if __name__ == '__main__':
dm_data=_get_io()
for line in dm_data:
if fields[0] in s_value:
s_value[fields[0]].append(fields[10])
else:
s_value[fields[0]]=[fields[10]]
if fields[0] in u_value:
u_value[fields[0]].append(fields[11])
else:
u_value[fields[0]]=[fields[11]]
print s_value
print u_value
Python output:=
{'dm-30': ['18.27', '2.00', '0.40'], 'dm-31': ['18.28', '3.00', '0.70']}
{'dm-30': ['6.36', '1.00', '0.50'], 'dm-31': ['6.37', '1.50', '0.60']}
I wanted to combine s_value and u_value with each Max value like bellow
{'dm-30': ['2.0', '1.0'], 'dm-31': ['3.0', '1.50']}
or just get the Max value for each dm in s_value and u_value
like bellow
{'dm-30':2.00, 'dm-31': ['3.00]}
{'dm-30': [1.00], 'dm-31': [1.50]}
Any help will be really appreciable
