Some issues/fixes in your code 

<ul>
<li>You actually don't need <code>GetX</code> and <code>GetY</code>, you can refer the attributes <code>x</code> and <code>y</code> directly.</li>
<li><code>&amp;&amp;</code> is not valid syntax in Python, instead you use <code>and</code></li>
<li>The first argument of <code>__eq__</code> will be <code>self</code></li>
<li>You can use <code>f-strings</code> to format your string if you are using python3.6+, else you can use format strings</li>
<li>You can optionally raise a <code>TypeError</code> to ensure <code>other</code> is of type <code>Coordinate</code></li>
</ul>

Hence the updated code will look like

<pre><code>class Coordinate(object):
 def __init__(self, x, y):
 self.x = x
 self.y = y

 def __str__(self):
 #Use a f-string to format your string representation
 return f'&lt;{self.x},{self.x}&gt;'

 #If python3.5 and below, you can use format string as below
 #return '&lt;{},{}&gt;'.format(self.x, self.y)

 def __eq__(self, other):
 #If other is not an instance of Coordinate, raise TypeError
 if not isinstance(other, Coordinate):
 raise TypeError('An instance of class Coordinate is expected')
 #Compare both coordinates and return True or False
 return self.x == other.x and self.y == other.y
</code></pre>

Then you can use the class like as follows

<pre><code>c1 = Coordinate(5,5)
c2 = Coordinate(6,6)

print(c1)
#&lt;5,5&gt;
print(c2)
#&lt;6,6&gt;
print(c1 == c1)
#True
print(c1 == c2)
#False
print(c1 == 1)
#TypeError: An instance of class Coordinate is expected
</code></pre>

So many small mistakes ...

<ul>
<li><code>GetX</code> is not the same as <code>getX</code></li>
<li>an <code>if</code> statements needs a <code>:</code> at the end</li>
<li>the indentation of <code>__init__</code> clause is wrong</li>
<li><code>&amp;&amp;</code> does not exist in python, it's called <code>and</code></li>
<li>the <code>__eq__</code> function does not always return, it needs an <code>else</code> clause, or just return the boolean expression directly</li>
<li>the first argument of <code>__eq__</code> needs to be <code>self</code></li>
</ul>

<pre class="lang-py prettyprint-override"><code>class Coordinate(object):
 def __init__(self, x, y):
 self.x = x
 self.y = y
 def getX(self):
 # Getter method for a Coordinate object's x coordinate.
 # Getter methods are better practice than just
 # accessing an attribute directly
 return self.x
 def getY(self):
 # Getter method for a Coordinate object's y coordinate
 return self.y
 def __str__(self):
 return '&lt;' + str(self.getX()) + ',' + str(self.getY()) + '&gt;'
 def __eq__(self, otherPoint):
 return self.getX() == otherPoint.getX() and self.getY() == otherPoint.getY()
</code></pre>

I need to Add an eq method that returns True if coordinates refer to same point in the plane (i.e., have the same x and y coordinate) and am confused on how to do that. 

I have tried some code using eq and I am still getting errors and I am not quite sure why. 

<pre><code>class Coordinate(object):
 def __init__(self, x, y):
 self.x = x
 self.y = y
 def getX(self):
 # Getter method for a Coordinate object's x coordinate.
 # Getter methods are better practice than just
 # accessing an attribute directly
 return self.x
 def getY(self):
 # Getter method for a Coordinate object's y coordinate
 return self.y
 def __str__(self):
 return '&lt;' + str(self.getX()) + ',' + str(self.getY()) + '&gt;'
 def __eq__(Coordinate, otherPoint):
 if self.GetX() == otherPoint.getX()&amp;&amp; self.GetY() == otherPoint.getY()
 return True

x=5
y=5
</code></pre>

The expected output would return true if both coordinates were the same number and false if x and y were not the same numbers.

Modifying class in Python using __eq__

Python

我需要添加一个eq方法，如果坐标引用平面中的同一个点(即，具有相同的x和y坐标)，则返回True，但我对如何做感到困惑。我已经尝试了一些使用eq的代码，但我仍然收到错误，我不太确定为什么。class Coordinate(object):        def __init__(self, x, y):        ...
