> **Note**: **`itertools`** is a module in Python that provides functions. These functions help in iterating through iterables.

The **`tee()`** method in the `itertools` module gets independent iterators for the given iterable. The number of iterators to return is specified as a function argument. The tee iterators do not ensure thread safety.

#    
## Syntax

```python
itertools.tee(iterable, n=2)
```

## Parameters

- **`iterable`**: The iterable for which iterators need to be returned.
- **`n`**: The number of iterators to return.

## Example 1

import itertools

lst = ['a', 'b', 'c']

iter_1, iter_2 = itertools.tee(lst, 2)

print("Iterator 1 - ", list(iter_1))
print("Iterator 1 - ", list(iter_1))
print("Iterator 2 - ", list(iter_2))

# 
## Explanation

- Line 1: We import the `itertools` module.
- Line 3: We define a list of characters called `lst`.
- Line 5: Two iterators are obtained from `lst` using the `tee()` method where `lst` and `2` (`n`) are passed as arguments.
- Lines 7–9: The iterators obtained are printed by converting them to `list`.

The output shows that line 8 prints an empty list, indicating that `iter_1` is already traversed in line 7.

## Coding example 2

import itertools

lst = range(4, 10)

iter_1, iter_2 = itertools.tee(lst, 2)

print("Iterator 1 - ", list(iter_1))
print("Iterator 1 - ", list(iter_1))
print("Iterator 2 - ", list(iter_2))

# 
## Explanation

- Line 1: We import the `itertools` module.
- Line 3: We define the iterable of numbers called `lst` ranging from `4` to `10`. We use the `range()` method for this.
- Line 5: Two iterators are obtained from `lst` using the `tee()` method where `lst` and `2` (`n`) are passed as arguments.
- Lines 7–9: The iterators obtained are printed by converting them to `list`.

The output shows that line 8 prints an empty list, indicating that `iter_1` is already traversed in line 7.

What is the itertools.tee() method in Python?

The tee() method in Python's itertools module creates independent iterators from a provided iterable. The number of iterators is specified by the user.
