     The idea is to handle complicated code response (even multi lines).
     We get the status code in two ways:
     - extracting the code from the last valid line in the response
-    - getting it from the 3first digits in the code
-    After a comparaison between the two values,
+    - getting it from the 3 first digits in the code
+    After a comparison between the two values,
     we can safely set the code or raise a warning.
 
     Examples:
-        - get_code('200 Welcome') == 200
+        - get_status_code_from_code_response('200 Welcome') == 200
 
         - multi_line_code = '226-File successfully transferred\n226 0.000 seconds'
-          get_code(multi_line_code) == 226
+          get_status_code_from_code_response(multi_line_code) == 226
 
-        - multi_line_with_code_conflits = '200-File successfully transferred\n226 0.000 seconds'
-          get_code(multi_line_with_code_conflits) == 226
+        - multi_line_with_code_conflicts = '200-File successfully transferred\n226 0.000 seconds'
+          get_status_code_from_code_response(multi_line_with_code_conflicts) == 226
