Question

I am trying to solve this Python homework question in MyProgrammingLab that I have:

Given the list value_list, assign the number of nonduplicate values to the variable distinct_values.

Here are the answers I need to get: https://imgur.com/a/lX3g1kR

Is there an easy way to solve this? My programmingLab says I shouldn't be using print or insert statements

Answer 1

For that python has the set function:
distinct_values = set(value_list)

Answer 2

Benjamin Jürgens answer is right...

however, this give you a set, not the length of the set ^^

to get count of distinct values, you should do:

distinct_values_count = len(set(value_list))

Answer 3

if print is not allowed then make a function with return statement.

Answer 4

looks like you may have to do a loop.

for value in value_list:
distinct_values = len(set(value))

Answer 5

Thank you all for your help with my question.
