L1-008 求整数段和 python

python 实现

sr=input()
start=int(sr.split(' ')[0])
end=int(sr.split(' ')[1])

sum=0
count=0
diff=end-start+1
for i in range(start,end+1):
    sum+=i
    count+=1
    print("{:5d}".format(i),end='')
    if count%5 == 0 or count == diff:
        print()
print("Sum = {}".format(sum))
