Python 字符串 removeprefix() 方法

描述

removeprefix() 方法在 Python 3.9 版本中引入。它会删除字符串开头的子串，并返回剩余的字符串。

语法

var.removeprefix(prefix)

参数

prefix − 要从字符串开头删除的字符串

返回值

removeprefix() 方法返回删除前缀字符串后的字符串。

示例

var = 'Explicit is better than implicit'
var1 = var.removeprefix('Ex')
print ("原始字符串:", var)
print ("删除前缀后:", var1)

var = "Explicit is better than implicit"
var2 = var.removeprefix('Explicit is ')
print ("原始字符串:", var)
print ("删除前缀后:", var2)

var = 'Explicit is better than implicit'
var3 = var.removeprefix("")
print ("原始字符串:", var)
print ("删除前缀后:", var3)

它将产生以下输出−

原始字符串: Explicit is better than implicit
删除前缀后: plicit is better than implicit
原始字符串: Explicit is better than implicit
删除前缀后: better than implicit
原始字符串: Explicit is better than implicit
删除前缀后: Explicit is better than implicit
