You can type cast a sequence of elements to a list using the list() function. The code below turns a tuple into a list.

t1 = ( "apple", "banana", "cherry" )
print( t1 )
print( type( t1 ) )
fruitlist = list( t1 )
print( fruitlist )
print( type( fruitlist ) )

This is sometimes necessary, in particular when you have an “iterator” available and you want to use the elements in a list format. An iterator is a function that generates a sequence (more on iterators is given in Chapter 24¹). An example of an iterator that I already discussed is the range() function. The range() function generates a sequence of numbers. If you want to use these numbers as a list, you can use list casting.

numlist = range( 1, 11 )
print( numlist )
numlist = list( range( 1, 11 ) )
print( numlist )

You can turn a string into a list of its characters by using a list casting on the string.
