Python exercise need explanations

Question

Q: Write a Python program which accepts a sequence of comma-separated numbers from user and generate a list and a tuple with those numbers.

Code:
values = input("Input some comma seprated numbers : ")

list = values.split(",")

tuple = tuple(list)

print('List : ',list)
print('Tuple : ',tuple)

Input some comma seprated numbers : 3,5,7,23
List : ['3', '5', '7', '23']
Tuple : ('3', '5', '7', '23')

I understand how tuples function, can someone explain to me how lost was created in this exercise ?

It is not recommended to use functions (e.g. list, tuple) as variable names as they can mess up with your code.
