Basic python question
Hello, I am new to python and trying to do some basic things with python. I am writing a script that runs a df command and I need parts of that output saved in 2 different variables. Is this something that can be done? I can do this by running multiple df commands but would prefer to make only one call: -- inode_cmd = "/bin/df --output=pcent,ipcent /var| grep -v Use | tr '%' ' '" output = subprocess.check_output( inode_cmd, stderr=subprocess.STDOUT, shell=True ) -- But this would end up giving me the following: #df --output=pcent,ipcent /var | grep -v Use | tr '%' ' ' 5 1 I would like variable x to be 5 and variable y to be 1. Is there a easier way to do this? Thanks in advance for your guidance. -- https://mail.python.org/mailman/listinfo/python-list
Re: Basic python question
Thanks Aldwin that helps but it looks like it is reversing the numbers for some reason: the df command returns the following: 7 2 I used your example and did: x,y = set(output.split()) My assumption would be that x should be 7 and y should be 2. However, when I print x and y it seems to be reversed (x is 2 and y is 7). Am I missing something?

Re: Basic python question
Thanks again Aldwin. This seems to work, guess it is the set that is flipping the numbers: x,y = (output.split()) Much appreciated!

Print formatting
Hello, I am new to python and trying to write a script that outputs some data about users. I was able to write it and dump the data but can't seem to align the output in column 2 correctly. Here is what I am trying to do: -- output: user1 data1 username2 data2 user3 data3 snip from script: print(str(temp_list[0]) + "\t\t" + str(temp_list[1])) -- Adding the tabs does not seem to work and I am sure there is a better way to do this. Any help would be appreciated. Thanks, -J -- https://mail.python.org/mailman/listinfo/python-list
Re: Print formatting
I seem to have found a way to do this with the following:
print('{:<12s}{:>12s}'.format((temp_list[0]),(temp_list[3])))
Still let me know if there is a better way to format this output :)
Thanks,
-J

python2 vs python3
Hello,
I am writing my second python script and got it to work using
python2.x. However, realized that I should be using python3 and it
seems to fail with the following message:
--
Traceback (most recent call last):
File "test_script.py", line 29, in
test_cmd = ("diskcmd -u " + x + " | grep -v '\*' | awk '{print $1,
$3, $4, $9, $10}'" )
TypeError: Can't convert 'bytes' object to str implicitly
--
I then run this command and save the output like this:
--
test_info = (subprocess.check_output( test_cmd,
stderr=subprocess.STDOUT, shell=True )).splitlines()
--
Looks like the command output is in bytes and I can't simply wrap that
around str(). Thanks in advance for your help with this.
