To verify that a string is a keyword you can use <a href="https://docs.python.org/3/library/keyword.html#keyword.iskeyword" rel="noreferrer"><code>keyword.iskeyword</code></a>; to get the list of reserved keywords you can use <a href="https://docs.python.org/3/library/keyword.html#keyword.kwlist" rel="noreferrer"><code>keyword.kwlist</code></a>:

<pre><code>&gt;&gt;&gt; import keyword
&gt;&gt;&gt; keyword.iskeyword('break')
True
&gt;&gt;&gt; keyword.kwlist
['False', 'None', 'True', 'and', 'as', 'assert', 'break', 'class', 'continue', 'def', 
 'del', 'elif', 'else', 'except', 'finally', 'for', 'from', 'global', 'if', 'import', 
 'in', 'is', 'lambda', 'nonlocal', 'not', 'or', 'pass', 'raise', 'return', 'try', 
 'while', 'with', 'yield']
</code></pre>

If you want to include built-in names as well (Python 3), then check <a href="https://docs.python.org/3/library/builtins.html" rel="noreferrer">the <code>builtins</code> module</a>:

<pre><code>&gt;&gt;&gt; import builtins
&gt;&gt;&gt; dir(builtins)

For Python 2 you'll need to use <a href="https://docs.python.org/2/library/__builtin__.html" rel="noreferrer">the <code>__builtin__</code> module</a>

Is the list of Python reserved words and builtins available in a library? I want to do something like:

<pre><code> from x.y import reserved_words_and_builtins

 if x in reserved_words_and_builtins:
 x += '_'
</code></pre>

Is the list of Python reserved words and builtins available in a library?

Python

库中有Python保留字和内置的列表吗？我想做一些类似的事情： from x.y import reserved_words_and_builtins if x in reserved_words_and_builtins:     x += '_'
