Programming

Upload your .py file using the Student File Upload link by 11:59 pm on the due date. For each problem, start your solution by using the characters #%% on the first line of your solution. These three characters create a cell in Spyder. For questions that do not require you to write a program, write your answers using Python comments which start with the hash symbol #. For example, if you were asked to explain what the int function does then you would type the following in the Spyder editor:

#%% Problem 1

# The int() function is a built-in function that returns

# an integer object constructed from a number

# or string, or returns 0 if no arguments are given.

Or you can use triple quotes:

#%% Problem 1

""" The int() function is a built-in function that returns

an integer object constructed from a number

or string, or returns 0 if no arguments are given."""

Problems

1. What are the data types introduced in Chapter 1? Give an explicit code example of when it is not possible to convert one data type into another.
2. Do a Google search for "python built-in functions" and list four functions not already discussed in Chapter 1 of the textbook. Briefly explain the purpose of each function and use each one in an explicit code example.
3. Why does the expression below cause an error? How can you fix it?

   "On average, the Bills score" + 27 + "points at a home game."

4. What are the seven basic math operators supported by Python? List each one and for each one give an explicit code example.
5. Write a program that asks the user to input a distance in kilometers and outputs the distance in miles. For example, if the user inputs 230 for kilometers, your program would print to the screen:

   "230 kilometers equals 143 miles."

   Remember that the function input returns a string and you cannot do math operations with strings.
6. Write a program that asks the user to input two numbers, the first number is "the numerator" and the second is "the denominator", and outputs the corresponding fraction as a string and the nearest integer to the fraction. For example, if the user inputs 5 as the numerator and 2 as the denominator, then the printed string should be:

   "The fraction 5/2 rounded to the nearest integer is 2."
