Python While/For 循环

Question

我怎样才能把它变成一个while循环并输出同样的东西？？？？

for x in range(56,120) :
    if (x < 57) :
          summation = 0
    summation = x + summation
    if (x == 119) :
          print (“Sum of integers from 56 to 120 is”, summation)

Answer 1

summation = 0
start_val = 56
stop_val  = 120
while start_val < stop_val:
    summation += start_val
    start_val += 1
print summation

Answer 2

有多种方法，但其中一种是：

x = 56
while x < 120:
    ...
    x += 1

Answer 3

sum = 0
x = 56
while x < 120:
    sum += x
    x += 1
print(sum)

和平！
