If you don't escape the '\' python interprets your string as it should include a tab (to which the sign is \t). That is exactly why get 'heta' and a tab in front of it. The solution suggest by joris is also possible, since it tells python to pass a raw string to latex and not interpret it. WebThe most common technique is to use the command line program of libptp called ptpcam. You can put ptpcam in a bash shell script or run a system process from the language you are using. For example, in Python, you can use the subprocess module. In Dart, you can use the Process class. I am using the process_run package. arena kota kemuning https://joesprivatecoach.com
