Keep open a cmd window

Question

I have a python code in a program that opens a cmd window and runs there another program. The code looks like:

os.chdir('C:/Abaqus_JOBS' + JobDir)
os.system('abaqus job=' + JobName + '-3_run_rel2 user=FalseworkNmm41s interactive')

Now everything works but I get an error in the cmd window and next it closes very quickly not letting me see what was the error. How can I prevent this cmd window to close?

Answer 1

Add + " & timeout 15" or + " & pause" to the string you pass to os.system :

os.chdir('C:/Abaqus_JOBS' + JobDir)
os.system('abaqus job=' + JobName + '-3_run_rel2 user=FalseworkNmm41s interactive' + " & timeout 15")

consider using popen ( Difference between subprocess.Popen and os.system ) instead.

Answer 2

只需使用命令“暂停”，它会要求您按一个键继续。

Answer 3

os.chdir('C:/Abaqus_JOBS' + JobDir)
os.system('abaqus job=' + JobName + '-3_run_rel2 user=FalseworkNmm41s interactive')
raw_input("Press Enter...")

Answer 4

All of these work. I prefer the input("press enter"), but at fist I imported time, and added time.sleep(500), which would give me 500 secs to see what's going on. You can put in even more seconds.
