The code above finds all the files in some_directory/, iterates over them and uses .endswith() to print out the filenames that have the .txt file extension. Running this on my computer produces the following output:Shell data_01.txt data_03.txt data_03_backup.txt data_02_backup....

First, you pick Matplotlib’s theme with a dark background for a more dramatic visual effect. Then, you set up the figure and an Axes object, remove the default border around your visualization, and iterate over the windows. On each iteration, you clear the plot, hide the ticks, and fix...
print(card) ... room weapon person To iterate over the values rather than the keys, you use the dictionary’s values() function: >>> for value in accusation.values(): ... print(value) ... ballroom lead pipe Col. Mustard To return both the key and value as a tuple, you can use...
The first obvious reason for this is, in wildcard imports, the names with a leading underscore don't get imported. This may lead to errors during runtime. Had we used from ... import a, b, c syntax, the above NameError wouldn't have occurred. >>> from module import some_weird_...

My code calls channel.history() and iterates over messages in the channel. This is the trailing end of the stack trace I get: async for message in channel.history(limit=None, after=history_after): File "/home/circleci/.cache/pypoetry/virtualenvs/juniorguru-3aSsmiER-py3.8/lib/python3.8/...
