Python字符串 – removesuffix()

如果字符串以后缀结尾并且后缀不为空，则str.removesuffix(suffix, /)函数将删除后缀并返回字符串的其余部分。如果未找到后缀字符串，则返回原始字符串。它是在Python 3.9.0 版本中引入的。

Syntax: str.removesuffix(suffix, /)

Parameters:

Suffix– suffix string that we are checking for.

Return value:

Returns: string[ : – len (suffix) ] if the string ends with suffix string and that suffix is not empty. Else it returns the copy of original string.

示例 1：

# Python 3.9 code explaining
# str.removesuffix()
  
# suffix exists
print('ComputerScience'.removesuffix('Science'))
  
# suffix doesn't exist
print('GeeksforGeeks'.removesuffix('for'))

输出：
