Python 1-2+3-4....99=? Here's the question, I see other people's writing, a variety of, oneself also write a

f = ""
s = ""
i = 1
sum = 0
While I < 100:
if I%2 = = 1 and i < 99:
f = "-"
sum = sum + I
elif i = = 99:
f = "="
sum = sum + I
elif I%2 = = 0:
F = "+"
sum = sum-i
s = s + str (i) + F
i + = 1
Print (S,sum)

#同时我也看到有人这样写的, inspired ...

s = ""
Start = 1
sum = 0
While start < 100:
temp = start% 2
If temp ==1:
If start ==1:
s = str (start)
Else
s = s + "+" + str (START)
sum = sum + start
Else
s = s + "-" +str (start)
sum = Sum-start
Start + = 1
Print (s)
Print (sum)

#我发现人的想象力真是无穷的, although the problem is complicated to think, but also a good solution to the problem is the last equal sign is not printed
