E$101$ Fall $2024$

Exam $1$

$6.)(15$ points$)$ Write a Python program that defines a function named cm$2$in$.$ This function takes one float as a parameter and returns a float. The parameter is the length in

centimeters. The function converts the length to inches by dividing it by $2\mathrm{.}54.$ The function then returns this value. The program should prompt the user for the length in centimeters, call the cm$2$in function to convert the length to inches, and then print the value returned from the function.

$5.)(15$ points$)$ Create a Python program that defines a function named count$\_1$s$.$ This function takes an arbitrarily long list of integers as a parameter. The function should look at each list element to determine if the value is $1.$ The function should return the total number of times the integer $1$ occurs in the list.

The program should call the function with the following list as the argument.

my$\_$list $=[1,2,3,4,5,2,3,5,1]$

Print the resulting count that is returned from the program.
