In Python, you can convert lists list and tuples tuple to each other by using list() and tuple().
Tóm lược đại ý quan trọng trong bài
For the sake of convenience, the word “convert” is used , but in reality a new object is generated, and the original object remains the same.
list() and tuple() return new list and tuple when given an iterable object such as list, tuple, set, range, etc.
In the following sample code, list, tuple, and range type objects are used as examples.
l = [0, 1, 2]
print(l)
print(type(l))
# [0, 1, 2]
#
t = (‘one’, ‘two’, ‘three’)
print(t)
print(type(t))
# (‘one’, ‘two’, ‘three’)
#
r = range(10)
print(r)
print(type(r))
# range(0, 10)
#
source: list_tuple.py
See the following article for details on range().

By passing an iterable object such as tuple as an argument of list(), list with the elements of passed iterable is generated.
tl = list(t)
print(tl)
print(type(tl))
# [‘one’, ‘two’, ‘three’]
#
rl = list(r)
print(rl)
print(type(rl))
# [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

Since tuple is immutable, you can not add, change or remove elements, but after making list with list() and adding, changing, deleting elements of list, you can get updated tuple by using tuple() again.
