Hey everyone, I am really new to Python contribution community want to propose below methods for List object. Forgive me if this is not the format to send an email. 1. *list.replace( item_to_be_replaced, new_item )*: which replaces all the occurrences of an element in the list instead of writing a new list comprehension in place. 2. *list.replace( item_to_be_replaced, new_item, number_of_occurrences )*: which replaces the occurrences of an element in the list till specific number of occurrences of that element. The number_of_occurrences can defaulted to 0 which will replace all the occurrences in place. 3. *list.removeall( item_to_be_removed )*: which removes all the occurrences of an element in a list in place. What do you think about these features? Are they PEP-able? Did anyone tried to implement these features before? Please let me know. Thank you, Sukumar
