List manipulation in Python :

List is one of the simplest data structures in Python.Its very important and Lists are enclosed in square brackets [ ]. each item is separated by a comma.Every List item assign unique index no. A list is mutable, meaning you can change its contents. Lists have many built-in control functions.

Methods of List objects are:

Creation:

```
L = ['yellow', 'red', 'blue', 'green', 'black'] 
```

print L :

```
['yellow', 'red', 'blue', 'green', 'black'] 
```

Accessing/Indexing :

```
L[0]  = 'yellow' 
```

Slicing:

```
L[1:4]  = ['red', 'blue', 'green'] 
```

```
L[2:]   = ['blue', 'green', 'black']
L[:2]   =  ['yellow', 'red']
L[-1]   =  'black'
L[1:-1] = ['red', 'blue', 'green']
```

Lengthof items in list :

```
len(L)  =  5 
```

Sorting the list :

```
sorted(L) = ['black', 'blue', 'green', 'red', 'yellow'] 
```

Append to end of list:

```
L.append("pink")
```
