+# Python slice(start:stop[:step])
+
+`slice(start:stop[:step])` is an object usually containing a portion of a sequence. A slice is created using the subscript notation, [] with colons between numbers when several are given, such as in variable_name[1:3:5].
+
+## Arguments
+
+This function can be used to slice tuples, arrays and lists.
+
+The value of the `start` parameter (or None if not provided)
+
+The value of the `stop` parameter (or last index of sequence)
+
+The value of the `step` parameter (or None if not provided). It cannot be 0.
+
+All three must be of integer type.
+
+
+## Return
+
+If only `stop` is provided, it generates portion of sequence from index `0` till `stop`.
+
+If only `start` is provided, it generates portion of sequence after index `start` till last element.
+
+If both `start` and `stop` are provided, it generates portion of sequence after index `start` till `stop`.
+
+If all three `start`, `stop` and `step` are provided, it generates portion of sequence after index `start` till `stop` with increment of index `step`.
+
+
+
+## Example
+
+```python
+a = [ 1, 2, 3, 4, 5, 6, 7, 8]
+print(a[:5])    # prints [1, 2, 3, 4, 5]
+print(a[2:])    # prints [3, 4, 5, 6, 7, 8]
+print(a[2:5])    # prints [3, 4, 5]
+print(a[2:7:2])    # prints [3, 5, 7]

 # Python Range
 
-**TODO: `range` basic info**

 [Python Docs - Ranges](https://docs.python.org/3/library/stdtypes.html#ranges)
 
+Rather than being a function, range is actually an [immutable sequence type](https://docs.python.org/3/library/stdtypes.html#immutable-sequence-types) and is commonly used for looping a specific number of times in for loops.
+
 **Creation:**
 
 `ranges` are created using the `range` constructor. The parameters for the constructor are:
