利用python实现关键词搜索文件功能。输入信息包括需要搜索的文件夹路径和文件关键词，输出结果为文件的绝对路径，如下给出三个函数，和程序执行用法：
#-*- coding:utf-8 -*- #===============================# #Brief : search file by keyword #Date : 2022-1-1 #Support : youcunwang1@163.com #===============================#
#=========================#
# import part
#=========================#
import os,sys
#
def search_file(ipath,keyword):
# get ./
if not os.path.isdir(ipath):
ipath = os.getcwd()
# file walk
x = os.walk(ipath)
for a, b, c in x:
for i in c:
if keyword in i:
key_path = os.path.join(a, i)
key_path = os.path.abspath(key_path)
print(' file get || abspath : %s' %(key_path))
#
def usage():
print("python xx.py <-ipath path> <-key keyword> ")
sys.exit(1)
#
def main():
argc = len(sys.argv)
if argc < 5:
usage()
#
for i,j in enumerate(sys.argv):
#
if j in ['-ipath']:
ipath = sys.argv[i+1]
#
elif j in ['-key']:
key = sys.argv[i+1]
#
elif j in ['-h']:
usage()
#
search_file(ipath,key)
#
# Entry
main()
如下给出简单示例：输入路径为当前所在路径，关键词为py，
python 03_search_key.py -ipath ./ -key py
输出结果为：
