Renaming functions
A funny, cool, and useful trick. If you have to write a single function multiple times (usually range() on for loops), then you can simply assign a variable by the function's name, no parentheses. An example assignment is:
r=range
Thing is, this can only apply to save bytes if the function name is long enough to save more from the times it was used than the cost of assigning it to a variable. If not even twice, it's unnecessary. There're rarely any answers using this format for this exact reason. There aren't a lot of times where you'd need to keep adding the same function on the program when it comes to golfing.
