Python While/For loop

问题

how can I make this into a while loop and output the same thing????

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)

回答1:

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

回答2:

There are various methods, but one of them is:

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

回答3:

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

peace!
