do not use java and be clear please .... your answers not all right

so, please be clear in your answer

Extracted text: Exercise 1: Write a python program that reads from a text file whose name is provided by the user and including lines relating to the dimensions of three kinds of shapes: Circle, Triangle, Trapezoid (see figure below for a sample input file). For each shape compute and display its area: - Triangle area = base X height. - Circle area = n radius². - Trapezoid area =; (base 1 + basez)X height. Your program should consider the following erroneous cases: The file does not open/exist • The format of the data in the file is incorrect (e.g. shape name = 'Polygon'), the shape's dimensions are incorrect (e.g. negative value or number of values for a trapezoid not equal to 3: base,, base, and height, or), in which case RuntimeError exception should be raised and the processing should continue. Shape Area Triangle: Circle: -10 50 48 Triangle Circle Trapezoid: 10 12 70 1200.00 Trapezoid: 9 32 » invalid dimension Trapezoid Trapezoid 770.00 > missing data. Sample input file Sample output
