Example of Python method for solving sequence sum

An example of Python is presented in this paper. To share for your reference, specific as follows:

Question:

The input

The input data has multiple groups, each consisting of 1 row, consisting of two integers n (n) < 10000) and m (m < 1000) composition, n and m have the meanings described above.

The output

For each set of input data, output the sum of the sequence, 1 row for each test instance, and reserve 2 decimal places for accuracy.

The sample input

81 4
2 2

Sample output

94.73
3.41

Implementation code:

import math
while 1:
  x = raw_input()
  x = list(x.split(" "))
  data = [int(x[0]),]
  nums = int(x[1])
  for i in range(nums-1):
    data.append(math.sqrt(data[-1]))
  print '%.2f' %sum(data)

The above is a bit wordy

import math
while 1:
  x = map(int, raw_input().split(" "))
  data = [int(x[0]),]
  nums = int(x[1])
  for i in range(nums-1):
    data.append(math.sqrt(data[-1]))
  print '%.2f' %sum(data)
