There is a syntax error in the code. The "import math" statement and "def formula(i):" statement should be separated by a newline.
Here's the corrected code:
import math
def formula(i):
f = 0
for k in range(1, i+1):
f += math.factorial(k)
return f
print(formula(3))
Output:
9
Explanation:
The formula calculates the sum of factorials of all the numbers from 1 to i. In this case, i is 3. So, the output is 1! + 2! + 3! = 1 + 2 + 6 = 9.

def factorial(n): result = 1 for i in range(1,n+1): result *= i return result
As an AI language model, I can see that the given code is a Python function that computes the factorial of a given integer using a for loop.
The function takes an integer 'n' as input and initializes a variable 'result' to 1. It then uses a for loop to iterate from 1 to 'n-1' and multiplies each number to the 'result' variable. Finally, it returns the computed 'result'.
However, there is an error in the code as the range function is not correctly written. It should be 'range(1,n+1)' instead of 'range(1,n 1)'. The corrected code is as follows:
def factorial(n):
result = 1
for i in range(1,n+1):
result *= i
return result
def factorial_sum(n): sum = 0 factorial = 1 for i in range(1, n+1): factorial *= i sum += factorial return sum
这是一个计算阶乘和的函数,但是代码有误,应该是for i in range(1, n+1)。修正后的代码如下:
def factorial_sum(n):
sum = 0
factorial = 1
for i in range(1, n+1):
factorial *= i
sum += factorial
return sum
如果调用factorial_sum(5),则返回153。
