== Noncompliant Code Example

----
import tempfile

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

== Compliant Solution

----
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
----
