跨文件夹转移到文件
#将part5 下的mm.py 移动到part6abc文件夹
import os
import sys
BASE_BIR = os.path.dirname(os.path.dirname(__file__))
sys.path.append(BASE_DIR)
def move_file(file,folder):
if not (os.path.exists(file) and os.path.isfile(file)):
print('文件不存在或非法')
return False
if not as path.exists(folder):
os.makedirs(folder)
file_name = os.path.split(file)[1]
new_file = os.path.join(folder,file_name)
with open(file,'rb') as rf,open(new_file,'wb') as wf:
for line in rf:
wf.write(line)
os.remove(file) #核心部分:复制代码,删除原代码
file = os.path.join(BASE_DIR,'part5','mm.py')
folder = os.path.join(BASE_DIR,'part6','abc')
move_file(file,folder)
遍历打印目标路径中所以txt文件
def print_txt(folder):
if not os.path.exists(folder) or os.path.isfile(folder):
return
for path in os.listdir(folder):
file_path = os.listdir(folder)
if os.path.isfile(file_path) and file_path.endswith('.txt'):
print(path) #.txt文件
elif os.path.isdir(file_path):
print_txt(file_path) #递归 文件夹中.txt文件
