+# Iterate Over A Dictionary
+
+Let's say we have a `dict` that contains counts of occurrences for each word in
+some sample text:
+
+```python
+words_frequency = {
+    "the": 4,
+    "a": 3,
+    "dog": 1,
+    "bone": 1,
+    "wants": 1,
+    ...
+}
+```
+
+Here is how we can iterate over the `dict`, accessing both the keys and values:
+
+```python
+for word, count in word_frequency.items():
+    print(f"- {word} appears {count} time{'' if count == 1 else 's'}")
+```
+
+Using the
+[`items()`](https://docs.python.org/3/library/stdtypes.html#dict.items) method,
+we're able to access both _key_ and _value_ with the for loop as it iterates.
+
+Another approach is to loop directly on the `dict` which implicitly surfaces the
+_key_ for iteration. This can then be used to get the value from the `dict`:
+
+```python
+for word in word_frequency:
+    print(f"- {word}: {word_frequency[word]}
+```
