迭代 判断数字 累加器

s20 = "I am sylar, I'm 14 years old, I have 2 dogs!"
count = 0
for c in s20:　　　　　　　　　　　　# 迭代器  if 变量 in可迭代的对象
    if c.isdigit():
#         count = count + 1
# print(count)                 # 检查里面有几个数字

for c in s20:
    if c.isdigit():                      # if c.isdigit    # 判断是不是数字  if c.isdigit()

        count = count + int(c)　　　　# 累加器,---注意str变int型,  用int()     count= count+int()

print(count)
