Can t upvote so I ll repost  jfs comment cause I think it should be more visible       AnneTheAgile  shell True is not required  Moreover you should not use   it unless it is necessary  see   valid s comment   You should pass   each command-line argument as a separate list item instead e g   use     command    arg 1    arg 2   instead of  command  arg 1   arg 2          jfs Mar 3  15 at 10 02

No such file or directory can be also raised if you are trying to put a file argument to Popen with double-quotes   For example   call args     mv     path to file with spaces txt     somewhere     In this case  you need to remove double-quotes   call args     mv    path to file with spaces txt    somewhere

Use shell True if you re passing a string to subprocess call   From docs      If passing a single string  either shell must be True or   else the string must simply name the program to be executed without   specifying any arguments    subprocess call crop  shell True    or   import shlex subprocess call shlex split crop
