#105895 — Using python heredoc to substitute the external file read by python script.

Hi all,

See the following python codes:

import os
from subprocess import check_output

# POSIX: name shall not contain '=', value doesn't contain '\0'
output = check_output("source /home/werner/env-intel-toolchains.sh;
         env -0", shell=True, executable="/bin/bash")


In the above codes, I use the file /home/werner/env-intel-toolchains.sh 
for subprocess.check_output to use for its operation.

If I want to use python heredoc to substitute this external file for the 
above codes.  Is this possible?  

Regards

What do you mean by “Python heredoc”? What Python feature are you
referring to?

I find the following methods currently:

import subprocess

subprocess.Popen(
"""
cat <<EOF > new.txt
Hello World!
EOF""", shell=True)

subprocess.Popen(
"""
cat <<EOF | sh
source /opt/intel/composer_xe_2011_sp1.11.339/bin/ifortvars.sh intel64
source /opt/intel/composer_xe_2011_sp1.11.339/bin/iccvars.sh intel64
source /opt/intel/composer_xe_2011_sp1.11.339/mkl/bin/mklvars.sh intel64 
lp64 mod
source /opt/intel/impi/4.1.0.024/intel64/bin/mpivars.sh
env -0
EOF
""", shell=True,
executable = "/bin/bash",)

or 

import subprocess
subprocess.check_output(
"""
cat <<EOF | sh
source /opt/intel/composer_xe_2011_sp1.11.339/bin/ifortvars.sh intel64
source /opt/intel/composer_xe_2011_sp1.11.339/bin/iccvars.sh intel64
source /opt/intel/composer_xe_2011_sp1.11.339/mkl/bin/mklvars.sh intel64 
lp64 mod
source /opt/intel/impi/4.1.0.024/intel64/bin/mpivars.sh
env -0
EOF
""", shell=True,
executable = "/bin/bash",)

It seems the above code will do the job for me.

I don't understand what you're trying to do. But I think you have fixed
your problem:

If I understand correctly this sentence, you now have a satisfactory
solution. Good!
