1. Write a Python program “Lab7B.py” to complete the following: • Define a method/function randoms_to_file(n, n1, n2, filename) such that n random integers (positive or negative) in the range of [n1, n2] are generated and will be written to the file with the name of “filename”. • Define a method/function read_file_and_process() such that: o Prompt for a filename of file to be opened for inputs, you need to use while-loop with try except in case of the incorrect input of the file n...

1. 1. After having completed the above Q1, then write a Python program “Lab6B.py” to complete the following: • Define a class Student with 3 data attributes: name, college, major o The class should have __init__ method for initiation of the above data attributes. o Define __str__ method, in this way, the object created from this class can be “printed out” giving the object information. (Hints: refer website at Define a sub-class GraduateStudent (that inherits class Student defined ...

1. 1. A palindrome is a word or a phrase that reads the same way backwards as forwards. Write a function that accepts a text string as input and determines whether or not the text string is a palindrome. Then write a program “Lab5B” that uses this function. Prompt the user to enter a word or phrase and then inform the user whether or not the text entered qualifies as a palindrome. [Hint: there is a REVERSE method for a string. But to compare a string reversed this way, you need to convert to...

1. Write a program “Lab4B” that prompts the user to enter a string and then: 1. Display the length of the string. 2. Convert all the vowels into lowercase and display the modified string. 3. Display a count of each of the vowels and the total number of vowels in the string. 4. Convert the string into list of words and display the length of the list. (Note: the input vowels may be either uppercase or lowercase letters.) 2. Write a program “Lab4B”that keeps prompting the user (unti...

1. Write a program “Lab3B” that prompts the user to enter a number in the range 1 to 999.99 (inclusive) and validates the input by using while-loop. Loop until user enters: 555.55. Print the inputted number with 2 decimal places 2. Write a program “Lab3B”that creates a list of 5 integers (prompting for inputs and add to the list one by one), print the list. Then convert the list to a tuple (simply with use of the function tuple(..) ) and print the tuple in reversed order. You need...
