s = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'
num=0
while True:
if num>19
break
num=num+1
ss=s[0:num]
print(ss)
這個是哪里錯了.

if num>19

老师这个答案好像错了哦！
我写的是，供参考
num=1
sum=0
while num <= 9:
if num % 2==0:
sum = sum + num
num=num+1
continue
num=num+1
print(sum)

for i in T:
if '(' in str(i):
s+=1
print(s)
s = 0
for i in T:
if '(' in str(i):
s+=1
