计算题解析_计算方法真题?

只需要把{}和[]都换成()，然后用eval()

while True:
    try:
        s = input()
        s = s.replace('{', '(')
        s = s.replace('}', ')')
        s = s.replace('[', '(')
        s = s.replace(']', ')')
        print(int(eval(s)))
    except:
        break

要包含最后一个数字

while True:
	try:
		n = int(input())
		count = 0
		for i in range(1,n+1):
		    if i % 7 == 0:
		        count += 1
		    else:
		        k = i
		        while k >0:
		            if k % 10 == 7:
		                count += 1
		                break
		            k //=10
		print(count)
	except:
		break

python写很简单，但是好像不是那么回事儿

while True:
	try:
		s1 = int(input())
		s2 = int(input())
		print(s1+s2)
	except:
		break

好像考察的是这个

while True:
    try:
        s1 = input()[::-1]
        s2 = input()[::-1]
        j = 0
        summ = 0
        re = ''
        for i in range(max(len(s1),len(s2))):
            if i < len(s1):
                l1 = int(s1[i])
            else:
                l1 = 0
            if i < len(s2):
                l2 = int(s2[i])
            else:
                l2 = 0
            summ = (j + l1 + l2) % 10
            j = (j + l1 + l2) // 10
            re = str(summ) + re
        if j > 0:
            re = str(j) + re
        print(re)
    except:
        break
