<p>字典不包含重复的键。最后输入的<code>key</code>将由字典存储。你知道吗</p>
<pre><code>dictt = {'a' : 22, 'a' : 33, 'c' : 34, 'd' : 456}
# This is your dictionary.
# Now print the dictionary to see it.
print(dictt)
</code></pre>
<p>输出:-</p>
<pre><code>{'a': 33, 'c': 34, 'd': 456}
# Now this is your dictionary. Now on whatever the operation you will perform, you are perfroming on this dictionary.
</code></pre>
<p>我希望这对你有帮助。你知道吗</p>
