Command line recall in python terminal treats strings case insensitively.

Example:
Define a 'dummy' function that takes a string as input. If you run dummy twice with the same input string, but different cases, it only saves one.
>>> dummy("This is a test") # run this
>>> dummy("THIS IS A TEST") # run again w/ different string
Now if you try cmd recall, it only recalls the first.
I believe it should recall both.
Maybe it's treating one as a duplicate - erroneously?

By default, reading input from the console uses the console's built-in command-line editor. You can clear the console input history with Alt+F7; display the history list with F7; navigate in the history list with the up and down arrow keys, even when the list isn't displayed; recall the first and last entries of the list with page up and page down; and cycle through matching command completions with F8.

Having said that, the new implementation of the console in Windows 10 has a bug in the "Discard Old Duplicates" history option [1]. Try disabling this option in the console's "Properties" dialog, which can be accessed from the Alt+Space control menu.

Thanks, I didn't know about the F7 or F8 commands.

My 'Discard Old Duplicates' was already disabled (default?).
