I am trying to retrive error(exit code importantly) thrown by any command line execution in python script itself. I am using subprocess for this. When I execute any wrong commands then it throws an error in terminal as usual, but then it stops executing python file and I can't get store error.
Look at the code. p_status is supposed to store exit code. But before printing it stops the script after throwing error in terminal.
process = subprocess.Popen([<command>], stdout = subprocess.PIPE)
output = process.communicate()
p_status = process.wait()
print(p_status)
I went through different solutions and tried all of them but couldn't get the required result.
Got this problem solved using the following code:
try:
subprocess.Popen([<command>], stdout = subprocess.PIPE)
except OSError as error:
print(error.errno) #for exit code
