Python 如何延迟一次打印一行多行字符串？

我想输出上面的例子，一次一行，延迟0.5秒。我发现了一种打印字符的方法，这种方法也有同样的效果，但打印字符时会有延迟。

分割行；打印时迭代每一行，然后在打印后休眠

string = """This is a
very long string,
containing commas,
that I split up
for readability"""

import time

string = """This is a
very long string,
containing commas,
that I split up
for readability"""

for line in string.splitlines():
    print(line)
    time.sleep(0.5)
