为什么是70分阿，PyCharm上没问题阿

n = int(input())
for i in range(n):
    l = input().split(' ')
    if len(l) == 3:
        f = l[0]
        a, b = int(l[1]), int(l[2])
    else:
        f = 'a'
        a, b = int(l[0]), int(l[1])
    if f == 'a':
        ch = str(a) + '+' + str(b) + '=' + str(a + b)
        print(ch + '\n' + str(len(ch)))
    if f == 'b':
        ch = str(a) + '-' + str(b) + '=' + str(a - b)
        print(ch + '\n' + str(len(ch)))
    if f == 'c':
        ch = str(a) + '*' + str(b) + '=' + str(a * b)
        print(ch + '\n' + str(len(ch)))
