# # Comparison Operators 
# 
# In this lecture we will be learning about Comparison Operators in Python. These operators will allow us to compare variables and output a Boolean value (True or False). 
# 
# If you have any sort of background in Math, these operators should be very straight forward.
# 
# First we'll present a table of the comparison operators and then work through some examples:
# 
# ## Table of Comparison Operators
# 
# <table class="table table-bordered">
# <tr>
# <th style="width:10%">Operator</th><th style="width:45%">Description</th><th>Example</th>
# </tr>
# <tr>
# <td>==</td>
# <td>If the values of two operands are equal, then the condition becomes true.</td>
# <td> (a == b) is not true.</td>
# </tr>
# <tr>
# <td>!=</td>
# <td>If values of two operands are not equal, then condition becomes true.</td>
# <td>(a != b) is true</td>
# </tr>
# <tr>
# <td>&lt;&gt;</td>
# <td>If values of two operands are not equal, then condition becomes true.</td>
# <td> (a &lt;&gt; b) is true. This is similar to != operator.</td>
# </tr>
# <tr>
# <td>&gt;</td>
# <td>If the value of left operand is greater than the value of right operand, then condition becomes true.</td>
# <td> (a &gt; b) is not true.</td>
# </tr>
# <tr>
# <td>&lt;</td>
# <td>If the value of left operand is less than the value of right operand, then condition becomes true.</td>
# <td> (a &lt; b) is true.</td>
# </tr>
# <tr>
# <td>&gt;=</td>
# <td>If the value of left operand is greater than or equal to the value of right operand, then condition becomes true.</td>
# <td> (a &gt;= b) is not true. </td>
# </tr>
# <tr>
# <td>&lt;=</td>
# <td>If the value of left operand is less than or equal to the value of right operand, then condition becomes true.</td>
# <td> (a &lt;= b) is true. </td>
# </tr>
# </table>

# Let's now work through quick examples of each of these.
# 
# ####Equal

# In[3]:


2 == 2


# In[4]:


1 == 0


# #### Not Equal

# In[5]:


2 != 1


# In[6]:


2 != 2


# In[7]:


2 <> 1


# In[8]:


2 <> 2


# #### Greater Than

# In[9]:


2 > 1


# In[10]:


2 > 4


# #### Less Than

# In[11]:


2 < 4


# In[12]:


2 < 1


# #### Greater Than or Equal to

# In[13]:


2 >= 2


# In[14]:


2 >= 1


# #### Less than or Equal to

# In[15]:


2 <= 2


# In[16]:


2 <= 4


# **Great! Go over each comparison operator to make sure you understand what each one is saying. But hopefully this was straightforward for you**
# 
# Next we will cover chained comparison operators
