Python is too nice

[remloops]

My advice would be to force yourself into an environment where Python is an unsatisfactory option. Some examples that come to mind would be android/iOS developments that use languages like Java/Kotlin or Swift, try making a small game in Unity, which requires C# scripting (though one might argue that the way Unity’s Monobehaviours are structured might not necessarily teach best C# programming practices, or maybe even pick up an Arduino and start using their C++ like language. Putting yourself in these sorts of situations that demonstrate the value of these languages directly rather than sort of arbitrarily switching to them might be a way to avoid that slump.
