<code>ax.set_title()</code> should set the titles for separate subplots:

<pre><code>import matplotlib.pyplot as plt

if __name__ == "__main__":
 data = [1, 2, 3, 4, 5]

 fig = plt.figure()
 fig.suptitle("Title for whole figure", fontsize=16)
 ax = plt.subplot("211")
 ax.set_title("Title for first plot")
 ax.plot(data)

 ax = plt.subplot("212")
 ax.set_title("Title for second plot")
 ax.plot(data)

 plt.show()

Can you check if this code works for you? Maybe something overwrites them later?

A shorthand answer assuming 
<code>import matplotlib.pyplot as plt</code>:

<pre><code>plt.gca().set_title('title')
</code></pre>

as in:

<pre><code>plt.subplot(221)
plt.gca().set_title('title')
plt.subplot(222)
etc...
</code></pre>

Then there is no need for superfluous variables.

blocks|key|4589473|text|如果你想让它更短，你可以这样写：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4589474|import+matplolib.pyplot+as+plt

 plt.subplot(2,2,i+1).set_title('Subplot n°{}' .format(i+1))
plt.show()

It makes it maybe less clear but you don't need more lines or variables

You are able to give every graph a different title and label by Iteration only.
<pre><code>titles = {221: 'First Plot', 222: 'Second Plot', 223: 'Third Plot', 224: 'Fourth Plot'}
fig = plt.figure()

As of matplotlib 3.4.3, the <a href="https://matplotlib.org/stable/api/figure_api.html#matplotlib.figure.Figure.add_subplot" rel="nofollow noreferrer">Figure.add_subplot</a> function supports kwargs with title as:
<pre><code>fig.add_subplot(311, title=&quot;first&quot;)
fig.add_subplot(312, title=&quot;second&quot;)
</code></pre>

I have one figure which contains many subplots.

<pre><code>fig = plt.figure(num=None, figsize=(26, 12), dpi=80, facecolor='w', edgecolor='k')
fig.canvas.set_window_title('Window Title')

# Returns the Axes instance
ax = fig.add_subplot(311) 
ax2 = fig.add_subplot(312) 
ax3 = fig.add_subplot(313) 
</code></pre>

How do I add titles to the subplots?

<code>fig.suptitle</code> adds a title to all graphs and although <code>ax.set_title()</code> exists, the latter does not add any title to my subplots. 

Thank you for your help.

Edit:
Corrected typo about <code>set_title()</code>. Thanks Rutger Kassies
