Checks if all elements in a list are equal.
|
|
|
|
- Use `set()` to eliminate duplicate elements and then use `len()` to check if length is `1`.
|
|
|
|
```py
|
|
def all_equal(lst):
|
|
return len(set(lst)) == 1
|
|
```
|
|
|
|
```py
|
|
all_equal([1, 2, 3, 4, 5, 6]) # False
|
|
all_equal([1, 1, 1, 1]) # True
|
|
```
