1、批量查找替换
# -*- coding: utf-8 -*-
import os
import re
# path=os.getcwd()str_old = 'insert'
str_new = 'frs.event.queue'
file_formate = 'init.sql'
file_sql=open(r'F:\bak\init_all.sql', 'r+', encoding='utf-8')
def replace_txt(path):if path.find(file_formate) == len(path) - len(file_formate):with open(path, 'r+', encoding='utf-8') as file:str = file.read()if str.find(str_old) > 0:print(path)str = str.replace(str_old, str_new)print(str)file.seek(0, 0)file.write(str)# file.close()
# replace_txt(r'D:\python\workspace\tools\util\txt12\test.txt.py')
def find_txt(path):with open(path, 'r+', encoding='utf-8') as file:i=0while True:line = file.readline()i=i+1if not line:breakelse:try:str_line = str(line)# if path.find(str_old) > 0:if str_line.find(str_old) >=0:print(str_line)breakexcept:print(str(line))
2、如果不知道文件是否utf-8
def find_txt_no_formate(path):if file_formate !='':if path.find(file_formate) == len(path) - len(file_formate):print(path)with open(path, 'r+', encoding='utf-8') as file:str = file.read()file_sql.write('\n--------------------------------')file_sql.write(path)file_sql.write(str)# find_txt(path)else:find_txt(path)
3、列出所有文件
def list_all_file(rootdir):files = []list = os.listdir(rootdir)for i in range(0, len(list)):path = os.path.join(rootdir, list[i])if os.path.isdir(path):files.extend(list_all_file(path))if os.path.isfile(path):files.append(path)try:find_txt_no_formate(path)except:print("e")return files
