Python字符串 rsplit() 方法
Python String rsplit()方法在用指定的分隔字符串字符串返回字符串列表。
Syntax:
str.rsplit(separator, maxsplit)
Parameters:
- separator: The is a delimiter. The string splits at this specified separator starting from the right side. It is not provided then any white space is a separator.
- maxsplit: It is a number, which tells us to split the string into a maximum of provided number of times. If it is not provided then there is no limit.
Return:
Returns a list of strings after breaking the given string from the right side by the specified separator.
Error:
We will not get any error even if we are not passing any argument.
示例 1
Python3
# Python code to split a string
# using rsplit.
# Splits at space
word = 'geeks for geeks'
print(word.rsplit())
# Splits at 'g'. Note that we have
# provided maximum limit as 1. So
# from right, one splitting happens
# and we get "eeks" and "geeks, for, "
word = 'geeks, for, geeks'
print(word.rsplit('g', 1))
# Splitting at '@' with maximum splitting
# as 1
word = 'geeks@for@geeks'
print(word.rsplit('@', 1))Python3
word = 'geeks, for, geeks, pawan'
# maxsplit: 0
print(word.rsplit(', ', 0))
# maxsplit: 4
print(word.rsplit(', ', 4))
word = 'geeks@for@geeks@for@geeks'
# maxsplit: 1
print(word.rsplit('@', 1))
# maxsplit: 2
print(word.rsplit('@', 2))Python3
word = 'geeks for geeks'
# Since separator is 'None',
# so, will be splitted at space
print(word.rsplit(None, 1))
print(word.rsplit(None, 2))
# Also observe these
print('@@@@@geeks@for@geeks'.rsplit('@'))
print('@@@@@geeks@for@geeks'.rsplit('@', 1))
print('@@@@@geeks@for@geeks'.rsplit('@', 3))
print('@@@@@geeks@for@geeks'.rsplit('@', 5))输出：
['geeks', 'for', 'geeks']
['geeks, for, ', 'eeks']
['geeks@for', 'geeks']示例 2
Python3
word = 'geeks, for, geeks, pawan'
# maxsplit: 0
print(word.rsplit(', ', 0))
# maxsplit: 4
print(word.rsplit(', ', 4))
word = 'geeks@for@geeks@for@geeks'
# maxsplit: 1
print(word.rsplit('@', 1))
# maxsplit: 2
print(word.rsplit('@', 2))
输出：
['geeks, for, geeks, pawan']
['geeks', 'for', 'geeks', 'pawan']
['geeks@for@geeks@for', 'geeks']
['geeks@for@geeks', 'for', 'geeks']示例 3
Python3
word = 'geeks for geeks'
# Since separator is 'None',
# so, will be splitted at space
print(word.rsplit(None, 1))
print(word.rsplit(None, 2))
# Also observe these
print('@@@@@geeks@for@geeks'.rsplit('@'))
print('@@@@@geeks@for@geeks'.rsplit('@', 1))
print('@@@@@geeks@for@geeks'.rsplit('@', 3))
print('@@@@@geeks@for@geeks'.rsplit('@', 5))
输出：
['geeks for', 'geeks']
['geeks', 'for', 'geeks']
['', '', '', '', '', 'geeks', 'for', 'geeks']
['@@@@@geeks@for', 'geeks']
['@@@@', 'geeks', 'for', 'geeks']
['@@', '', '', 'geeks', 'for', 'geeks']
