  Generated Python code

  try:
      web_page = open_web_page('runavelo.com', "Google Chrome", '30', None)
      click_web_element(web_page, ElementDescriptor('f65c8477-c610-4973-9cef-8d5463631c1a', "Download"), {"clickOption":"CDP Silent Click"})
  except OutOfTimeException as e:
      print_to_app(f'Timeout exception:{e}', {"renderHtml":False})
  except Exception as e:
      print_to_app(f'Other exceptions:{e}', {"renderHtml":False})

• Use a lock to serialize part of a parallel loop

  Generated Python code

  mylock = check_and_convert_vars(threading.RLock(), "Any type")
  def ____parallel_execute2(____rpa_gen_itr_loop_index, item):
      with mylock:
          print_to_app(f"Parallel execution: {item}", {"renderHtml":False})
          pause_sec(3)
          print_to_app(f"Execution completed: {item}", {"renderHtml":False})
  parallel_loop(['a','b','c'], False, ____parallel_execute2)

• Read a file with with

  [
      {
        "ins": "Indented Workflow",
        "in": "with open('hello.txt') as f:",
        "children": [
          {
            "ins": "Run Python Code",
            "in": {
              "Python Code": "result = f.read()"
            }
          },
          {
            "ins": "Print Log",
            "in": {
              "Log Content": "result",
              "Render HTML": "False"
            }
          }
        ]
      }
  ]
  

  Generated Python code

  with open("hello.txt") as f:
      result = f.read()
      print_to_app(result, {"renderHtml":False})

• In addition to using the Count Loop command, you can write a Python for statement in an Indented Workflow.

  [
    {
      "ins": "Indented Workflow",
      "in": "for i in range(3):",
      "children": [
        {
          "ins": "Print Log",
          "in": {
            "Log Content": "i",
            "Render HTML": "False"
          }
        }
      ]
    }
  ]

  Generated Python code

  for i in range(3):
      print_to_app(i, {"renderHtml":False})
