用多个字符分割字符串（python）[重复]

Ok so I know I can split a string using the .split method every time a character/a sequence of characters appears - for example, in the following code, when I use the .split method, the <string> is splitted every time : appears in it

<string>.split(":")

但是我不能给它提供多个参数，因此，如果出现其中一个参数，则字符串将被拆分。

例如，给定此输入字符串：

input_string = """ \ hel\lo ="world"""

I want to split the input_string every time \, =, ", or <blank space> appears, so that i get the following output:

['hel', 'lo', 'world']

我知道解决方案可能是：

non_alfanumeric = """\\=" """
input_string = """ \ hel\lo ="world"""

for char in non_alfanumeric:
    input_string = input_string.replace(char, " ")

list = input_string.split(" ")
while "" in list:
    list.remove("")

but this would be too much computationally slow if the input string is very long, because the code has to check the whole string 4 times: first time for \, second time for =, third time for ", fourth time for <blank space>.

还有什么其他解决方案？
