 # pyPtr
  Pointers for Python
+
+## Usage
+ To create a new `Pointer`:
+ ```python
+ import ptr
+
+ num: int = 10
+ num_pointer: ptr.Pointer = ptr.Pointer(num)
+ ```
+
+ To get the address and value that the pointer points to:
+ ```python
+ num_pointer_address: int = num_pointer.getAddress()
+ num_pointer_value: int = num_pointer.getVal()
+ ```
+ 
+ To perform calculations:
+ ```python
+ # += and -=
+ num_pointer.increment()
+ num_pointer_value_after_plus_equals: int = num_pointer.getVal()
+
+ num_pointer.decrement()
+ num_pointer_value_after_minus_equals: int = num_pointer.getVal()
+
+
+ # + and -
+ num_pointer.add(10)
+ num_pointer_value_after_plus: int = num_pointer.getVal()
+
+ num_pointer.sub(15)
+ num_pointer_value_after_minus: int = num_pointer.getVal()
+
+
+ # ==, !=, <, >, <= and >=
+ other: int = 15
+ other_pointer: ptr.Pointer = ptr.Pointer(other)
+
+ are_addresses_equal: bool = num_pointer.eqeq(other_pointer)
+ are_addresses_equal: bool = num_pointer.ne(other_pointer)
+ are_addresses_equal: bool = num_pointer.gt(other_pointer)
+ are_addresses_equal: bool = num_pointer.lt(other_pointer)
+ are_addresses_equal: bool = num_pointer.lte(other_pointer)
+ are_addresses_equal: bool = num_pointer.gte(other_pointer)
+ ```
