python 创立并写入新文件,
python 统计特定文件夹下的 word 和 pdf 的数量
import glob,os
path 就是你说的特定文件夹
path = r”D:\linshi”
这里的 pdf 能够换成 docx
file=glob.glob(os.path.join(path, “*.pdf”))
count = 0
for i in file:
count = count + 1
print(count)
复制文件的残缺门路借助 python 对该文件夹的文件批量复制到另一个指定文件夹中。有两种模式,一种只复制文件。第二种复制文件的残缺门路
import os
import shutil
def get_all_file_by_type(path, type=()): # 取得以 type 类型结尾的所有文件,返回一个 list
filelist = []
for a, b, c in os.walk(path):
for name in c:
fname = os.path.join(a, name)
if fname.endswith(type):
filelist.append(fname)
return filelist

filelist = []
for a, b, c in os.walk(path):
for name in c:
fname = os.path.join(a, name)
for string in string_list: # 遍历 string_list,如果文件门路中蕴含 string,那么 append 进 filelist
if string in fname: # 如果只想要文件名符合条件,把 fname 换成 name 即可
filelist.append(fname)
break
return filelist

if not requird_dir: # 如果仅复制文件
for file in file_list:
name = file.split("\\")[-1] # 取得文件名字
new_paths = os.path.join(new_path, name) # 与新门路拼接,取得残缺的新门路
shutil.copy(file, new_paths)
print(new_paths + "胜利")

python 压缩多个文件到 zip 格局 -zipfile 包实例
pip install zipfile
file=r’D:\test.zip’
out_path=r’D:\files’
遍历 files 文件夹下的文件,压缩发送
zip_1=zipfile.ZipFile(file,’w’)
for f in os.listdir(out_path):
zip_1.write(os.path.join(out_path,f),f,zipfile.ZIP_DEFLATED)
zip_1.close()
python 批量删除文件名_Python 批量批改文件名
import os, re

else:

用正则表达式匹配后缀名
if re.match(‘.+?.’+suffix+’$’,file) != None and keyword in file:
