 Python is very *nice* and will try to fix some common mistakes or oversights by itself.
 For example.

+#Logical Operators
+
+There is three types of logical operators. All operators returns boolean.
+
+| Operator        | Result                                       |
+|-----------------|----------------------------------------------|
+| **And**         | It send 'True' if all conditions are true    |
+| **Or**          | It send 'True' if one of conditions are true |
+| **Not**         | It reverse the boolean result                |
+
+
+Let's start example with 'And' operator!
+
+```python3
+CustomerName = "Jean"
+CustomerAgreement = True
+
+DealerName = "Paul"
+DealerAgreement = True
+
+if CustomerAgreement and DealerAgreement :
+    print(f"Youpi !!! {CustomerName} and {DealerName} are agreed ")
+else:
+    print(f"Oh no {CustomerName} and {DealerName} are disagreed ;( ")
+```
+As you can guess, Jean and Paul are agreeing to the deal. If I had put 'False' in DealerAgreement, the result will be inverse.

 The different built-in objects we've seen until now, such as `str` and `int` are simple [text](https://docs.python.org/3/library/stdtypes.html#text-sequence-type-str) and [numeric](https://docs.python.org/3/library/stdtypes.html#numeric-types-int-float-complex) types.
