python获取文件名的前缀和后缀

package main

import (
    "fmt"
    "path"
)
func main() {
    filename := "device/sdk/CMakeLists.txt"
    filenameall := path.Base(filename)    
    filesuffix := path.Ext(filename)
    fileprefix := filenameall[0:len(filenameall) - len(filesuffix)]
    //fileprefix, err := strings.TrimSuffix(filenameall, filesuffix)

    fmt.Println("file name:", filenameall)
    fmt.Println("file prefix:", fileprefix)
    fmt.Println("file suffix:", filesuffix)
}

file name: CMakeLists.txt
file prefix: CMakeLists
file suffix: .txt

path.Base(filename)：获取不包含目录的文件名

path.Ext(filename)：获取文件后缀

文件前缀 可以使用切片的方式获取：

fileprefix := filenameall[0:len(filenameall) - len(filesuffix)]

也可以使用 strings.TrimSuffix() 进行获取：

import "strings"

fileprefix, err := strings.TrimSuffix(filenameall, filesuffix)
