List vs tuple python

mylist : list = [] # <-- a list variable can be defined either as [] or <varname> : list
mytuple : tuple = () # <-- a tuple variable can be defined either as () or <varname> : tuple

List vs tuple

# compare the size
import sys
my_list = [0, 1, 2, "hello", True]
my_tuple = (0, 1, 2, "hello", True)
print(sys.getsizeof(my_list), "bytes")
print(sys.getsizeof(my_tuple), "bytes")

# compare the execution time of a list vs. tuple creation statement
import timeit
print(timeit.timeit(stmt="[0, 1, 2, 3, 4, 5]", number=1000000))
print(timeit.timeit(stmt="(0, 1, 2, 3, 4, 5)", number=1000000))
