        "xpath=//input[@name='fullName']",
        "xpath=//div[4]/div/label/input",
        "css=#react-root > section > main > div > div > div:nth-child(1) > div > form > div:nth-child(5) > div > label > input"

    },
    {
      "Command": "type",
      "Target": "name=password",
      "Value": "PASS_HERE",
      "Targets": [
        "name=password",
        "xpath=//*[@id=\"react-root\"]/section/main/div/div/div/div/form/div[6]/div/label/input",
        "xpath=//input[@name='password']",
        "xpath=//div[6]/div/label/input",
        "css=#react-root > section > main > div > div > div:nth-child(1) > div > form > div:nth-child(7) > div > label > input"
      ],
      "Description": ""
    }
  ]
}

So how to edit values of email,username and passowrd ones? Do i have to iterate over each Command dict? if so,how to find 'Command' that have email field for example? Because these dictionaries can be mixed and do not always follow each other

Answer 1

Problem solved.

Here is the solution. Just need to iterate over each Command Dict.

for each in data["Commands"]:
    if each["Target"] == 'name=fullName' :
        each['Value'] = 'New Value'  # just updating the required value.
