如何获得两个下划线之间的字符串？

Question

str = "IV_04.03.2019-10-56-45_example_c584536f-ab26-40ce-b5b6-386f755ba747_1.csv"

我想提取example部分和这个c584536f-ab26-40ce-b5b6-386f755ba747

Answer 1

>>> "IV_04.03.2019-10-56-45_example_c584536f-ab26-40ce-b5b6-386f755ba747_1.csv".split("_")[1:-1]
['04.03.2019-10-56-45', 'example', 'c584536f-ab26-40ce-b5b6-386f755ba747']

这将提取被下划线包围且内部不包含下划线的所有子字符串。你知道吗

Answer 2

str = "IV_04.03.2019-10-56-45_example_c584536f-ab26-40ce-b5b6-386f755ba747_1.csv"
s1= str.split("_")[2]
s2= str.split("_")[3]
print (s1)
print (s2)

输出：

example
c584536f-ab26-40ce-b5b6-386f755ba747
