Native list operations

These list operations have fast, optimized implementations. Other list operations use generic implementations that are often slower.

Construction

Construct list with specific items:

• [item0, ..., itemN]

Construct empty list:

• []
• list()

Construct list from iterable:

• list(x: Iterable)

List comprehensions:

• [... for ... in ...]
• [... for ... in ... if ...]

Operators

• lst[n] (get item by integer index)
• lst[n:m], lst[n:], lst[:m], lst[:] (slicing)
• lst1 + lst2, lst += iter
• lst * n, n * lst, lst *= n
• obj in lst

Statements

Set item by integer index:

• lst[n] = x

For loop over a list:

• for item in lst:

Methods

• lst.append(obj)
• lst.extend(x: Iterable)
• lst.insert(index, obj)
• lst.pop(index=-1)
• lst.remove(obj)
• lst.count(obj)
• lst.index(obj)
• lst.reverse()
• lst.sort()

Functions

• len(lst: list)
