如何在使用Python时阻止空格？

my_string = "Hello World"
my_string = my_string.replace(" ", "\0")

my_strings = ["Hello", "World"]
my_string = "".join(["\0" for _ in range(len(my_strings))]) + "".join(my_strings)

my_string = "Hello World"
my_strings = my_string.split(" ")
my_string = "".join(["\0" for _ in range(len(my_strings[0]))]) + my_strings[0] + "".join(["\0" for _ in range(len(my_strings[1]))]) + my_strings[1]
