The typical way assumes you have pip installed on your machine, and you download your python packages using pip install. In this tutorial, we will highlight a few.

In the event that one has already written their code but would like to create a requirements.txt file, there are many ways of doing this. One can create this file manually by adding all the packages the code is dependent on however, this is not always the case. Typically, the file that has information on all dependencies is called the requirements.txt file. To do this, an end-user may create a virtual environment and download all required packages to run the code in this environment. Instead, there should be a better way for someone to create the same python environment the developer of the code had when they developed the shared code.

For that reason, relying on the command line error messages to install the right packages is usually inefficient. Of course, one can follow through the error messages and install each of the required packages however, as projects grow, they tend to have many dependencies, and those dependencies may have dependencies as well.

Jupyter notebook run when the matplotlib package has not been downloaded The notebook clearly states that the module has not been found in the environment. The screenshot below shows a jupyter notebook that depends on the matplotlib package. Consequently, when they try to run your code, it might fail. However, when you distribute your code, other individuals may not have a similar environment with the same packages as yours. When programming in python, especially for machine learning, you may use many packages beyond the python standard library. To promote the readability and reproducibility of our work, we should all strive to effectively comment our code and highlight dependencies whenever we are developing code that has dependencies. Your code can also be accessible to others way after you have left the institution you are currently at, and it is no longer easy to contact you to understand your thought process.

I use the phrase “able to live after you” because your code can be the backbone of someone’s project years after you have departed. # do stuff, resulting in result (all on unicode strings)Įncoded_result = result.One of the most important things to accomplish when writing code is to write code that is able to live after you. In your case filename = 'where your data lives'ĭecoded_data = encoded_code('UTF16') Microsoft uses UTF16 as encoding for unicode strings, but decided to call it 'unicode' as they also use it internally.Įven if Python2 is a bit lenient as to string/unicode conversions, you should get used to always decode on input and encode on output. There's an explanation about the use of 'unicode' as an encoding on windows: What's the difference between Unicode and UTF-8? I highly recommend Ned Batchelder's presentation If you don't know the encoding, the best you can do is guess. Json_file = open('output_file.txt', 'w+')Īll data needs to be encoded to be stored on disk. # break up each line into a list such that each 'column' is a value in that list # make each line of input file a value in a list Here's the code: def txt_to_JSON(csv_list): While there are a number of questions out there on this topic, I didn't find a direct answer to my problem.ĭetecting the system defaults won't help me in this case, because I need the program to be portable.

Technical details: Python 2.7, Windows 7. encoding attribute), they both return None, which means they use the system default. When I detect the encoding of the input and output files (using. As far as I can understand, the problem has to do with the encoding, but I haven't been able to figure out what.

The output, however, contains gibberish instead of Hebrew characters that were present in the input file, and the output is double-spaced, horizontally (a whitespace character is added in between each character). From the input file I use readlines() to format the file as a list of rows, which I manipulate and concenate into a single string, which is then outputted into a separate. I'm writing a program to 'manually' arrange a csv file to be proper JSON syntax, using a short Python script.
