Invalid syntax when math and lists/ranges are involved

Question

sum_of_squares = sum(i ** 2) for i in range(1, 101)

I am attempting to square all numbers in a range and sum them up, but for whatever reason, when I run it, it gives me a syntax error pointing at for .

I've seen examples almost completely identical to this, several times online, but I cannot figure out what the issue is.

I am having major difficulties with math involving lists/ranges (another example being unable to see if an integer is divisible by all the numbers in a list; it only divides by the first number in the list, constant int and operand errors). any sources online that may be helpful?

Answer 1

You're right to use a generator, but your syntax is wrong:

sum(i ** 2 for i in range(1, 101))

The generator is the argument to sum . The above evaluates to 338350 .
