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.
