(10条消息) python_split()函数使用方法_檬柠wan的博客-CSDN博客_python split()方法https://blog.csdn.net/qq_45664055/article/details/118111074?ops_request_misc=&request_id=&biz_id=102&utm_term=python%20split()%E6%96%B9%E6%B3%95&utm_medium=distribute.pc_search_result.none-task-blog-2~all~sobaiduweb~default-4-118111074.142^v9^control,157^v4^control&spm=1018.2226.3001.4187
split("/")中有参数时，会以参数作为分割条件，把字符串进行分割，得到的每个分割段作为列表的元素返回
String_0 = "www.com/aaa/bbb/QJ6252630247.jpg"
String_1 = "www.com-aaa-bbb-QJ6252630247.jpg"
String_2 = "www.com:aaa:bbb:QJ6252630247.jpg"
a = String_0.split("/")
b = String_1.split("-")
c = String_2.split(":")
print(a)
print(b)
print(c)
结果：
['www.com', 'aaa', 'bbb', 'QJ6252630247.jpg']
['www.com', 'aaa', 'bbb', 'QJ6252630247.jpg']
['www.com', 'aaa', 'bbb', 'QJ6252630247.jpg']
第二个参数表示分割几次
String_0 = "www:com:aaa:bbb:QJ6252630247.jpg"
a = String_0.split(":", 1)
b = String_0.split(":", 2)
c = String_0.split(":", 3)
d = String_0.split(":", 4)
print(a)
print(b)
print(c)
print(d)
结果：
['www', 'com:aaa:bbb:QJ6252630247.jpg']
['www', 'com', 'aaa:bbb:QJ6252630247.jpg']
['www', 'com', 'aaa', 'bbb:QJ6252630247.jpg']
['www', 'com', 'aaa', 'bbb', 'QJ6252630247.jpg']
