python code for parsing command prompt data

[venkaaaaat]

hi,

can you please help me with a sample python code to retrive data from command prompt which appears after execution of some commanad

for eg: ./vershion.sh
gives ouput as

version: 7.0.0.9
type : NAS

thanks in advance

You can use the Command class in this code snippet. You would write

com = Command("./vershion.sh").run()
if com.failed:
    print(com.error)
else:
    print(com.output)

thanks a lot

this code works good but i need only some of the fields in output like version,type,etc,.

can you please help me with text parsing of required fields.

[Gribouillis]

Well, you can use split()

s = """
version: 7.0.0.9
type : NAS
"""

lines = s.strip().split("\n")
lines = [tuple(x.strip() for x in y.split(":")) for y in lines]

print(lines)

""" my output -->
[('version', '7.0.0.9'), ('type', 'NAS')]
"""

thank you for the code

here we assumed to get all the parameters in the output.
if there are more number of parameters, out of which we need to print version and type only

can you please help with the code to get out this

You have to post an example of how the other parameters look.
There are many ways to do this,if data is unformatet/changing regex can be and option.

import re

data = '''\
abc : 123
version: 7.0.0.9
type : NAS
ggg.2 : 4444
version: 8
type : FOO
hg.1234: test'''

result = re.findall(r"version.*|type.*", data)
print result
print zip(*[iter(result)]*2)
print [tuple(x.strip() for x in y.split(":")) for y in result] 

"""Output-->
['version: 7.0.0.9', 'type : NAS', 'version: 8', 'type : FOO']
[('version: 7.0.0.9', 'type : NAS'), ('version: 8', 'type : FOO')]
[('version', '7.0.0.9'), ('type', 'NAS'), ('version', '8'), ('type', 'FOO')]
"""

You must try some python code. We already gave 2 methods, where is your python code to extract the data ?

[vankaat]

is there any other way to get required fields, can it is possible with awk command
