Know the smallest number with Function min()

I want to know the smallest number of this list, which I present below the code.

I don’t know where I’m going wrong, I think I need to convert the list.

Example:

lista=[1, 3, 5]
def min(values):
    smallest = None
    for value in values:
        if smallest is None or values < smallest:
           smallest = value
    return smallest

menorvalor=min(lista)

The mistake you make is this

Typeerror: '<' not supported between instances of 'list' and 'int'

python python-3.x
  • 1

    correct value < smallest

  • values < smallest - shouldn’t be value < smallest? (value in the singular instead of values plural)

The problem is you’re comparing the list values and not the individual value value.

Wrong:

if smallest is None or values < smallest:
#                           ^^^ Essa é sua lista, e não o valor iterado

Corrected:

if smallest is None or value < smallest:
#                          ^ Aqui estamos comparando um por um


Staying:

lista=[1, 3, 5]
def min(values):
    smallest = None
    for value in values:
        if smallest is None or value < smallest:
           smallest = value
    return smallest

menorvalor=min(lista)

See working on IDEONE, with a more "shuffled" list to highlight the test.


To better understand

The line for value in values: "says" more or less like this:"For each item in values, execute the indented code below, with the item in the variable value each iteration (each execution)"
