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 radius?. - Trapezoid area = %3D ; (base 1 + base2)X height. 2 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.

Implement a function alterCase in Python that converts a word to "alterCase". Given a word, using any mix of upper and lower case letters, the function then returns the same word, except that the first letter is upper case, the second is lower case, and then cases of letters alternate throughout the rest of the word. >>> alterCase('apple')'ApPlE'
This is for Python version 3.8.5 and please include pseudocode. Write Python code that defines a void function named divide that takes two numbers as parameters and then prints the quotient accurate to 1 decimal place when the first parameter is divided by the second one.
n this lab, you complete a prewritten Python program for a carpenter who creates personalized house signs. The program is supposed to compute the price of any sign a customer orders, based on the following facts: The charge for all signs is a minimum of $35.00. The first five letters or numbers are included in the minimum charge; there is a $4 charge for each additional character. If the sign is make of oak, add $20.00. No charge is added for pine. Black or white characters are included in the minimum charge; there is an additional $15 charge for gold-leaf lettering.
Write a Python program with the following specifications: Write a program to simulate a clothing store that sells shirts, pants, and shoes. Define a function for each of these items, and use random number generation to assign a color, type, and size to each item. For example, one run of the shoe function may result in "BROWN BOOTS, 10.5" while another run might give you "RED SNEAKERS, 9.0". Output a list of items, the number of items on this list being either normally or exponentially distributed. Explain, using the context, why you selected the mean of this normal or exponential distribution, and, if it’s normal, the standard deviation.

In Java: Forms often allow a user to enter an integer. Write a program that takes in a string representing an integer as input, and outputs yes if every character is a digit 0-9. Ex: If the input is: 1995 the output is: yes Ex: If the input is: 42,000 or 1995! the output is: no Hint: Use a loop and the Character.isDigit() function.
