== Why is this an issue?

include::../description.adoc[]

=== Noncompliant code example

[source,python]
----
import tempfile

filename = tempfile.mktemp() # Noncompliant
tmp_file = open(filename, "w+")
----

=== Compliant solution

[source,python]
----
import tempfile

tmp_file1 = tempfile.NamedTemporaryFile(delete=False) # Compliant; Easy replacement to tempfile.mktemp()
tmp_file2 = tempfile.NamedTemporaryFile() # Compliant; Created file will be automatically deleted
