python 文本文件中查找指定的字符串

Question

如题所述

Answer 1

编写一个程序，能在当前目录以及当前目录的所有子目录下查找文件名包含指定字符串的文件，并打印出绝对路径。
import os
class SearchFile(object):

def __init__(self,path='.'):
self._path=path
self.abspath=os.path.abspath(self._path) # 默认当前目录

def findfile(self,keyword,root):
filelist=[]
for root,dirs,files in os.walk(root):
for name in files:
fitfile=filelist.append(os.path.join(root, name))
#print(fitfile)
print(os.path.join(root, name))
#print(filelist)
print('...........................................')
for i in filelist:
if os.path.isfile(i):
#print(i)
if keyword in os.path.split(i)[1]:
print('yes!',i) # 绝对路径
#else:
#print('......no keyword!')

def __call__(self):
while True:
workpath=input('Do you want to work under the current folder? Y/N:')
if(workpath == ''):
break
if workpath=='y' or workpath=='Y':
root=self.abspath # 把当前工作目录作为工作目录
print('当前工作目录：',root)
dirlist=os.listdir() # 列出工作目录下的文件和目录
print(dirlist)
else:
root=input('please enter the working directory:')
print('当前工作目录：',root)
keyword=input('the keyword you want to find:')
if(keyword==''):
break
self.findfile(keyword,root) # 查找带指定字符的文件

if __name__ == '__main__':
search = SearchFile()
search()
