+This is another example using `filter()` list in Python.
 
 For example, this algorithm filters the `all_numbers` list and returns a new list with only the odds numbers:
 
 ```py
 all_numbers = [23,12,35,5,3,2,3,54,3,21,534,23,42,1]
 
-def my_function(numb):
- return numb % 2 == 0
+def my_function(number):
+ return number % 2 == 0
 
 odd_numbers = list(filter(my_function, all_numbers))
 print(odd_numbers)
 ```
 
 ## 📝 Instructions:
