Working with Pandas DataFrames, you'll eventually face the situation where you need to find the maximum value for all of its columns or rows. Let's assume you already have a properly formatted DataFrame: import pandas as pd df_data = { "column1": [24, 9, 20, 24], "column2": [17,...

Array manipulation and element retrieval is a common task among any programming language, and luckily Python has some useful syntax for easily retrieving elements from various positions in the list. One common use case is to retrieve N elements from the end of a list/array, which we'll show how...
Assume you have a CSV (Comma Separated Values) file containing a dataset and would like to load it into memory for data manipulation with Python and Pandas. The process of importing a CSV is pretty straightforward. Although Python has a built-in CSV module for reading CSV files, the chance is...
When making the switch from CommonJS modules to ES modules, there are a few differences you'll notice. One error you'll likely run into is "Uncaught ReferenceError: __dirname is not defined in ES module scope". This error is exactly what it sounds like, the global __dirname variable is not...
A common error you'll run into, especially when transitioning from writing JavaScript in the Node runtime to writing JavaScript in the browser, is "Uncaught ReferenceError: require is not defined". The two environments have different ways of importing modules, so trying to import code in the browser like you...
A common error we see, especially among people who are new to JavaScript, is that they try to use the import statement when CommonJS is being used, which only uses the require statement. This results in the error "Uncaught SyntaxError: cannot use import statement outside a module". If...
Relative paths are convenient in that they specify the path of a file relative to the current working directory. However, they can also cause some issues due to ambiguity, and having the absolute path of a file is needed to be more explicit and avoid errors. Here we'll see how...
