Python Tutorial | Python List | Access Items in List | Change Items in List | Slicing
In this video, You will learn Python Lists.
"""Python List"""
"""
1. Lists store multiple items in a single variable.
2. Lists can store different data types while Array can't store.
3. Lists are mutable i.e Lists can be changed.
4. Lists allow duplicate values.
5. Lists insertion order is maintained.
6. Lists are represented using square brackets [] and
values are separated using comma (,).

"# Slicing in Lists"
"# In Slicing, range of index is provided that is" \
"Start index and End index"
"# End index-1 "
"# Last index is not considered in output and " \
"it runs upto the second last end index"
"# Example 1"
"# Start index and End index"

"# Example 2"
"# Leave End Index"

"# Leave Start Index and End Index"
"# It will print the complete list"

"from start to end "
