rstrip()方法返回字符串的副本，其中删除了尾随字符(基于传递的字符串参数)。如果未传递任何参数，它将删除尾随空格。
用法:
string.rstrip([chars])
参数：
chars(optional) – a string specifying the set of characters to be removed.
返回值：
returns a copy of the string with trailing characters stripped
代码1：
# Python3 program to demonstrate the use of
# rstrip() method using optional parameters
# string which is to be stripped
string = "geekssss"
# Removes given set of characters from
# right.
print(string.rstrip('s'))
输出：
geek
代码2：
# Python3 program to demonstrate the use of
# rstrip() method using optional parameters
# string which is to be stripped
string = " for "
# Leading whitespaces are removed
print("Geeks" + string.rstrip() + " Geeks ")
输出：
Geeks for Geeks
代码3：
# string which is to be stripped
string = "geeks for geeks"
# Argument doesn't contain trailing 's'
# So, no characters are removed
print(string.rstrip('ek'))
输出：
geeks for geeks
代码4：
# string which is to be stripped
string = "geeks for geeks"
# Removes given set of characters from
# right.
print(string.rstrip('ske'))
输出：
