python中split函数

String_0 = "bbb/QJ6252630247.jpg"
a = String_0.split("/")[-1]
b = String_0.split("/")[0]
print(a)
print(b)

# 结果：
# QJ6252630247.jpg
# bbb

str1= 'S1700028Y.svs'
c = str1.split('.')[0]
d = str1.split('.')[1]
e = str1.split('.')[-1]
print(c)
print(d)

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']
