write a python code for writing the addition testcase of asus calculator by using appiumserver of desired capabilities like

desired_caps['platformName'] = 'Android'

desired_caps['deviceName'] = 'Pixel XL API 33'

desired_caps['appPackage'] = 'com.asus.calculator'

desired_caps['appActivity'] = 'com.asus.calculator.Calculator' If the testcase is getting success and the if the testcase gets failed the output of testcase gets into logs.txt file so I want to get the error lines in red colour and bold in colored_log file I need a detailed code for that by using appium code
