# Python | Check if a list exists in given list of lists

Given a list of lists, the task is to check if a list exists in given list of lists.

```Input :
lst = [[1, 1, 1, 2], [2, 3, 4], [1, 2, 3], [4, 5, 6]]
list_search = [4, 5, 6]

Output:  True

Input :
lst = [[5, 6, 7], [12, 54, 9], [1, 2, 3]]
list_search = [4, 12, 54]

Output:  False
```

Let’s discuss certain ways in which this task is performed.

Method #1: Using Counter
The most concise and readable way to find whether a list exists in list of lists is using Counter.

 `# Python code find whether a list  ` `# exists in list of list. ` `import` `collections ` ` `  `# Input List Initialization ` `Input` `=` `[[``1``, ``1``, ``1``, ``2``], [``2``, ``3``, ``4``], [``1``, ``2``, ``3``], [``4``, ``5``, ``6``]] ` ` `  `# List to be searched ` `list_search ``=` `[``2``, ``3``, ``4``] ` ` `  `# Flag initialization ` `flag ``=` `0`  ` `  `# Using Counter ` `for` `elem ``in` `Input``: ` `    ``if` `collections.Counter(elem) ``=``=` `collections.Counter(list_search) : ` `        ``flag ``=` `1` `     `  `# Check whether list exists or not.     ` `if` `flag ``=``=` `0``: ` `    ``print``(``"False"``) ` `else``: ` `    ``print``(``"True"``) `

Output:

```True
```

Method #2: Using in

 `# Python code find whether a list  ` `# exists in list of list. ` ` `  `# Input List Initialization ` `Input` `=` `[[``1``, ``1``, ``1``, ``2``], [``2``, ``3``, ``4``], [``1``, ``2``, ``3``], [``4``, ``5``, ``6``]] ` ` `  `# List to be searched ` `list_search ``=` `[``1``, ``1``, ``1``, ``2``] ` ` `  `# Using in to find whether  ` `# list exists or not ` `if` `list_search ``in` `Input``: ` `    ``print``(``"True"``) ` `else``: ` `    ``print``(``"False"``) `

Output:

```True
```

Method #3: Using `any`

 `# Python code find whether a list  ` `# exists in list of list. ` ` `  `# Input List Initialization ` `Input` `=` `[[``1``, ``1``, ``1``, ``2``], [``2``, ``3``, ``4``], [``1``, ``2``, ``3``], [``4``, ``5``, ``6``]] ` ` `  `# List to be searched ` `list_search ``=` `[``4``, ``5``, ``6``] ` ` `  `# Using any to find whether  ` `# list exists or not ` `if` `any``(``list` `=``=` `list_search ``for` `list` `in` `Input``): ` `    ``print``(``"True"``) ` `else``: ` `    ``print``(``"False"``) ` `    `

Output:

```True
```
