赛高！我的最爱！直接把出题人卡你的地方手动改掉即可。

def deal(a):
    a = a.replace('^','**')
    a = a.replace(' ','')
    a = a.replace('()','')
    a = a.replace('/','//') #注意整除
    cnt = 0
    r = []
    for i in range(len(a)):
        if a[i] == '(':   cnt+=1
        elif a[i] == ')':
            if cnt == 0:    r.append(i)
            else:   cnt-=1
    la = list(a)
    for i in r: la.pop(i)
    n = len(la)
    cnt = 0
    l = []
    for i in range(n):
        if la[n - 1 - i] == ')':  cnt+=1
        elif la[n - 1 - i] == '(':
            if cnt == 0:  l.append(n - 1 - i)
            else:   cnt-=1

    a = ''.join(la)
    return a

s = input()
s = deal(s)
print(eval(s))
