Method 1: Get file creation & modification date or time in Python using the time module. We will use getctime() and getmtime() function found inside the path module in the os library, for getting the creation and modification times of the file. Both the above functions return time in seconds since EPOCH (00:00:00 UTC on 1 January 1970) (time is of float datatype). Since people typically only distribute bytecode files for code obfuscation purposes or smaller distribution size then only having to distribute a single .pyc should actually be beneficial to these use-cases.

Pikepdf is a Pythonic wrapper around the C++ QPDF library. Let's import it in our script: import pikepdf import sys. We'll also use the sys module to get the filename from the command-line arguments: # get the target pdf file from the command-line arguments pdf_filename = sys.argv[1] Let's load the PDF file using the library, and get the metadata:. . File metadata is everything associated with a particular file that is not the data content itself. The most obvious is the file name, but there are more parameters available such as the size of the file, the creation date, or its permissions.. Browsing through that data is important, for example, to filter files older than a date, or to find all files bigger than a value in KBs. We will write JSON file in Python using json.dump () method. Let's create json_example.py file and write the below code into this file. xxxxxxxxxx. 43. 1. import sys. 2. import requests. 3.

We can read the YAML file using the PyYAML module's yaml.load () function. This function parse and converts a YAML object to a Python dictionary ( dict object). This process is known as Deserializing YAML into a Python. This function accepts either a byte string, a Unicode string, an open binary file. As a handy shortcut, you can always assign a value for a given key regardless of whether it's already present in the metadata. If a tag was present, its value is overwritten. If the tag was not present, one is created and its value is set: >>> engine.metadata[key] = value. The EXIF data may optionally embed a thumbnail in the JPEG or TIFF format. 2022-7-7 · The file is one of these that can be freely downloaded here. import h5py filename = 'RAD_NL25_PCP_NA_202103111340.h5' f = h5py.File (filename, 'r') data = f ['image1'] ['image_data'] [:,:] This works to get a numpy array with the data.
