如何使用Python將文件名及其目錄路徑保存在文本文件中

Question

我正在嘗試查找目錄下文件中包含的字符串。 然后使其存儲在新文本文件或其他內容下的文件名和目錄。 我到了它正在通過目錄查找字符串的位置，然后打印結果。 但是不確定下一步。

請幫忙，我是編碼和python的新手。

import glob, os



#Open a source as a file and assign it as source
source = open('target.txt').read()
filedirectories = []

#locating the source file and printing the directories.
os.chdir("/Users/a1003584/desktop")
for root, dirs, files in os.walk(".", topdown=True):
    for name in files:
        print(os.path.join(root, name))
        if source in open(os.path.join(root, name)).read():
            print 'treasure found.'

Answer 1

如果您要查找字典，請不要進行字符串比較。 而是使用json模塊。 像這樣。

import json
import os

filesFound = []

def searchDir(dirName):
    for name in os.listdir(dirName):
        # If it is a file.
        if os.isfile(dirName+name):
            try:
                fileCon = json.load(dirName+name)
            except:
                print("None json file.")
            if "KeySearchedFor" in fileCon:
                filesFound.append(dirName+name)
        # If it is a directory.
        else:
            searchDir(dirName+name+'/')

# Change this to the directory your looking in. 
searchDir("~/Desktop")
open("~/Desktop/OutFile.txt",'w').write(filesFound)

這應該將輸出寫入csv文件

import csv
import os

with open('target.txt') as infile: source = infile.read()

with open("output.csv", 'w') as fout:
    outfile = csv.writer(fout)
    outfile.writerow("Directory FileName FilePath".split())
    for root, dirnames, fnames in os.walk("/Users/a1003584/desktop", topdown=True):
        for fname in fnames:
            with open(os.path.join(root, fname)) as infile:
                if source not in infile.read(): continue
            outfile.writerow(root, fname, os.path.join(root, fname))
