To check a directory, do: if my_file.is_dir():
Starting with Python 3.4, the pathlib module offers an object-oriented approach (backported to pathlib2 in Python 2.7): from pathlib import Path This follows symbolic links, so both islink() and isfile() can be true for the same path. Return True if path is an existing regular file. If you're not planning to open the file immediately, you can use os.path.isfile Checking and then opening risks the file being deleted or moved or something between when you check and when you try to open it. If the reason you're checking is so you can do something like if file_exists: open_it(), it's safer to use a try around the attempt to open it. TypeError: file() argument 1 must be encoded string without NULL bytes, not str Self.image = ImageTk.PhotoImage(Image.open(UUU))īut I get the following error: Traceback (most recent call last):įile "C:\Python26\GUI1.2.9.py", line 473, in įile "C:\Python26\GUI1.2.9.py", line 14, in _init_įile "C:\Python26\GUI1.2.9.py", line 431, in initializeįile "C:\Python26\lib\site-packages\PIL\Image.py", line 1952, in open I tried this snippet: with open("C:\Python26\seriph1.BMP", "rb") as f: Then developers can leverage the base64 module for encoding it. I want to convert the image to base64 format in order to insert it to my DB.
In the backend I refer a variable to the image with image request.files'image' That exports a FileStorage object. In the frontend application I have a form that contains an image upload feature. I want the actual image file to be encoded. For this, developers have to convert the Python string into a bytes-like object. I'm using Python Flask as my backend and faced a little problem. How do I specify the image I want to be encoded? I tried using the directory to the image, but that simply leads to the directory being encoded. I want to write the arrays to the database as base64 instead of converting the arrays to a string of unicode.I want to encode an image into a string using the base64 module. Using this django snippet I can store base64 data in a textfield: The reason I am asking is because I am working on a project where I would like to store a lot of Numpy arrays in a MySQL database in an app powered by django.

PYTHON ECODE IMAGE IN BASE64 ENCODING CODE
Using the code below as an example, how can I get a Numpy array from the base64 data if I know the dtype and the shape of the array? import base64 This question and answer suggest it is possible: Reading numpy arrays outside of Python but an example is not given. Here the string is to large to post but here is the image And when received by python the last 2 characters are although the str.
I am now trying to figure out how I can recover a numpy array from base64 data. I am trying to save an image with python that is Base64 encoded.
