Improve this answer. edited Apr 2 '20 at 12:13 Python number method exp () returns returns exponential of x: e x I am reading an Intro to Python textbook and came across this line: Operators on the same row have equal precedence and are applied left to right, except for exponentiation, which is applied right to left. I understand most of this, but I do not understand why they say exponentiation is applied right to left. They do not provide any examples either. Also, am I allowed to ask general questions like this, or are only problem solving questions preferred Whilst the exponent isn't empty: If the last (smallest) index of the exponent is 1, times result by the base. Remove the last index of the exponent. Multiply the base by it's self
