Stuck on Exercise 1.8 #3. Question is: Write a program using a for loop that calculates exponentials. Your program should ask the user for a base base and an exponent exp,
and calculate base^exp. Just not sure how to format it into a for loop. I created a script:
base = input("base: ")
expo = input("expo: ")
print base**expo
This essentially does what the exercise asks but I can't figure out how exactly to put it into a for loop.

if its for python : base=int(raw_input("base: ")) and same process for the other variable.

The assignment asks us to create a for loop which asks for a base and an exponent, and then calculates base^exp. I don't really understand how that would be formatted into a for loop in python.

probably cause you are not supposed ot use the ** operator...you have to recreate the exponential "function". mean if we have 5**3 then you could write it as 5*5*5 .....so think how to implement this with a for loop.

yeah that makes a lot more sense. i think im getting caught up more on the fact that the basic for loop structure i've been seeing in the MOOC is 'for x in range(a,b,c)' and that's not what I need to use here.

ok so the idea is: for loop is an iteration . so knowing that 5**3 can be written as 5*5*5 means you have to iterate 3 times. so if you call that a result you have: result=result*5 (or else written result*=5) and you want to iterate that 3 times: for i in range(0,3): (or for i in range(3):) result*=5 and print the result: print result you just have to substitute the 5 and 3 with the correct variables. hope this helped:)

range( ) can be called three different ways. This is called overloading a function. If range() is called with one argument, it assumes a starting value of 0, and a step value of 1, to a maximum value of the argument. If range() is called with two arguments, the first argument is the start value, the second argument is the max value, and a step value of 1 is assumed. If range() is called with three arguments, the first is the start value, the second is the max value, and the third is the step value. range() actually creates an iterable object (probably a list) and iterates over it. For big loops this can use a noticeable amount of memory, so I use xrange() instead.

It might be helpful to look at the Wikipedia "Exponentials" article.
