netAmount = 0

count = int(input())

for i in range(count):

    s = input()

    if operation=="D":

        netAmount+=amount

    elif operation=="W":

Answer 1

江湖之上有一招叫for-else，可以直接判断循环是否正常结束，无须每次循环判断一次

Answer 2

n=int(input())

dictionary={}

x=0

for i in range(0,n):

    k=input()

    k=k.split()

    if k[0]=='D':

        x=x+int(k[1])

    elif k[0]=='W':

        x=x-int(k[1])

    if x<0:

        print('Insufficient account balance')

        break

if x>=0:

    print(x)
