Redoc is a React app which means the actual HTML is being built in runtime: first the skeleton of the page loads, which also loads redoc javascript then the Redoc downloads the OpenAPI json (or yaml) file and renders the actual HTML dynamically based on it This is similar for many apps build with modern JS … Read more
Python 3.10 and above In Python 3.10, they introduced the pattern matching. Example from the Python Docs: Before Python 3.10 While the official docs are happy not to provide switch, I have seen a solution using dictionaries. For example: Then the equivalent switch block is invoked: This begins to fall apart if you heavily depend on fall through.
DataFrame.iterrows is a generator which yields both the index and row (as a Series):
Try That file only contains key value pairs where values are scalars. You can convert it to a dataframe with ser.to_frame(‘count’). You can also do something like this: Now data is a dictionary. You can pass it to a dataframe constructor like this:
Use a named tuple, which was added to the collections module in the standard library in Python 2.6. It’s also possible to use Raymond Hettinger’s named tuple recipe if you need to support Python 2.4. It’s nice for your basic example, but also covers a bunch of edge cases you might run into later as well. Your fragment above would … Read more
super() lets you avoid referring to the base class explicitly, which can be nice. But the main advantage comes with multiple inheritance, where all sorts of fun stuff can happen. See the standard docs on super if you haven’t already. Note that the syntax changed in Python 3.0: you can just say super().__init__() instead of super(ChildB, self).__init__() which IMO is quite a bit nicer. The … Read more
DataFrame.iterrows is a generator which yields both the index and row (as a Series):
The error message says that if you’re passing scalar values, you have to pass an index. So you can either not use scalar values for the columns — e.g. use a list: or use scalar values and pass an index:
The print() function writes, i.e., “prints”, a string in the console. The return statement causes your function to exit and hand back a value to its caller. The point of functions in general is to take in inputs and return something. The return statement is used when a function is ready to return a value to its caller. For example, here’s … Read more
It depends on how correct you want to be. \n will usually do the job. If you really want to get it right, you look up the newline character in the os package. (It’s actually called linesep.) Note: when writing to files using the Python API, do not use the os.linesep. Just use \n; Python automatically translates that to the proper newline … Read more
