This works fine when switching between “builtin” request methods. For example, in my get() method, I do something like this: curl

I can do git checkout . , but git checkout . adds directories excluded by sparse checkout There is git reset --hard , but it won't let me do it for a subdirectory: > git reset --hard . fatal: Cannot do hard reset with paths. Again: Why git can't do hard/soft resets by path? I can reverse-patch the current state

I would like the "with transaction cost" lines to be plotted with alpha=1 and linewidth=1 while I want the "no transaction costs" to be plotted with alpha=0.25 and linewidth=5 . But I would like the color to be the same for both versions of each strategy. I would like something along the lines of: fig, ax = plt.subplots(1, 1, figsize=(10, 10)) for c
