Today, I'd like to recommend some very useful in the field of office automation Python modular , It can help everyone improve efficiency in their work , Avoid repeating the mechanized operation process . Like to remember to collect 、 Focus on 、 give the thumbs-up
More technical exchanges , At the end of the article
When it comes to file system operation , I believe many people are still using Python In the middle of OS modular , By comparison ,Pathlib Modules have many advantages , Let's look at a few simple cases
For example, we can create and delete directories , The code is as follows
from pathlib import Path
currentPath = Path.cwd()
makePath = currentPath / 'pythonPractice'
makePath.mkdir()
So the same , The code for deleting the directory is
currentPath = Path.cwd()
delPath = currentPath / 'pythonPractice'
delPath.rmdir()
For example, we want to get the path of the current directory , The code is as follows
currentPath = Path.cwd()
print(currentPath)
And the directory where the computer user is located
homePath = Path.home()
print(homePath)
For example, we want to splice the absolute path of the desktop , The code is as follows
Path(Path.home(), "Desktop")
It can also be
Path.join
path(Path.home(), "Desktop")
For the specified path , We can judge whether it is a folder and whether it is a file , The code is as follows
input_path = r" Specified path "
if Path(input_path ).exists():
if Path(input_path ).is_file():
print(" It's a file ！")
elif Path(input_path ).is_dir():
print(" It's a folder ！")
else:
print(" The path is wrong !")
Python In the middle of glob The module is mainly used to find directories and files that meet specific rules , And return the search results to a list .
Because the module supports the use of regular wildcards to find , Therefore, it is particularly convenient to use , Let's take a look at a simple case ,
path1 = r".\[0-9].jpg"glob.glob(path1)
outut
['.\\1.jpg', '.\\2.jpg', '.\\3.jpg', ......]
Wildcards that are often used include
*： matching 0 One or more characters
**： Match all files 、 Catalog , Subdirectories and files in subdirectories
[]： Match characters in the specified range , for example [1-9] The match is 1-9 Characters within
[!]： Matches characters that are not in the specified range
Let's look at a few more cases , The code is as follows
for fname in glob.glob("./*.py"):
print(fname)
The above code prints out all the files in the current directory py Postfix file , Let's take another look at the case
for fname in glob.glob("./file[!0-9].py"):
print(fname)
The above code is printed out with filename Beginning with a non numeric symbol py file .
Finally, let's talk about how to achieve PDF Document conversion to Word The format of the document , The modules used are pdf2docx, We use first pip Command to install this module
pip install pdf2docx
Let's practice , The code is as follows
from pdf2docx import Converter
cv = Converter(r"pdf The specific path of the document ")
cv.convert("test.docx", start=0,end=None)
cv.close()
If it is a document with simple page elements ,pdf2docx Module processing is completely enough , But sometimes PDF Individual pages in the document are very colorful , convert to Word The format of the document will appear a little messy .
Finally, we can also convert for the specified number of pages , For example, it only operates on odd pages in the document , The code is as follows
from pdf2docx import Converter
cv = Converter(r"pdf The specific path of the document ")
cv.convert("test.docx", pages=[1, 3, 5, 7])
cv.close()
