  • main.py is a complicated program but it runs totally fine when executed directly with the terminal and with the same arguments. Commented Jun 12, 2016 at 7:06

    What errors are you getting when put inside the shell script? Is the shell script and the python script are on the same directory? Commented Jun 12, 2016 at 7:08
  • Yes, the shell script and the python script are in same directory. The error looks like this: ` Traceback (most recent call last): File "main.py", line 2, in <module> from cell import Cell File "/home/hasnain/Data/Studies/Courses/Current_Courses/Seminar/Code/Experiments/Without_LTS1/cell.py", line 9 def __init__(self, width:float, h:float=0.0, hu:float=0.0, hv:float=0.0, flux_r=array((0.0, 0.0, 0.0)), flux_l=array((0.0, 0.0, 0.0)), dt_cfl=0.0, kmax=0.0, k = 0.0): ^ SyntaxError: invalid syntax` Commented Jun 12, 2016 at 7:14

    Can you post the content of script.sh in full? Commented Jun 12, 2016 at 7:20
  • I have tried it both ways, with nested loops and with hardwired argumenrs In nested loops, it is like: ` arr_t=("1.0") arr_dt=("0.00158") arr_np=("10") for t in "${arr_t[@]}" do for dt in "${arr_dt[@]}" do for np in "${arr_np[@]}" do python main2.py $t $dt $np echo $t echo $dt echo $np done done done` Without loops it was: python main.py 1.0 0.1 10 It does not work either way.
