Data from CSV files can be easily exported in the form of spreadsheet and database as well as imported to be used by other programs. Let’s see how to parse a CSV file. Parsing CSV files in Python is quite easy.
$ python concatenate_video.py-c zoo.mp4 directed-by-robert.mp4-o output.mp4 Here I'm joiningzoo.mp4withdirected-by-robert.mp4files to produceoutput.mp4. Note that the order is important, so you need to pass them in the order you want. You can pass as many video files as you want....

When dealing with large amounts of data, either experimental or simulated, saving it to several text files is not very efficient. Sometimes you need to access a specific subset of the dataset, and you don't want to load it all to memory. If you are looking for a solution that integrates...
Yes, Python can handle large JSON files, but it may require more memory. Consider using chunking methods or libraries like Dask for very large datasets. Is it necessary to use pandas for this conversion? No, you can use Python’s built-in libraries like csv and json to perform the convers...
In this Python tutorial, we learned "How to Encrypt and Decrypt files in Python?". You can also encrypt and decrypt a file based on a simple and logical algorithm. But with the help of the Python cryptography library, you do not need to implement an algorithm of your own. You can simp...
Learn also: How to Encrypt and Decrypt PDF Files in Python. File Encryption Now you know how to basically encrypt strings, let's dive into file encryption; we need a function to encrypt a file given the name of the file and key: def encrypt(filename, key): """ Given a filename (...
In Python, some files are seen as text files where lines are delineated by the newline character\n. Typically, such files are opened with the parameterr. On the other hand, there are binary files, which need a different approach, similar to how they are managed in the C programming langu...
However, you can pass parse_dates if you’d like. You’ll get the same results.There are other functions that you can use to read databases, like read_sql_table() and read_sql_query(). Feel free to try them out!Remove ads Pickle Files Pickling is the act of converting Python ...
parse_constant (optional): a function that can be used to throw an exception when invalid numbers are encountered in JSON. object_pairs_hook (optional): a function will be called to decode an ordered list of pairs and return Python objects instead of a dict. The object_pairs_hook function...
