用python编写一段程序：输入一句中文句子，请编程统计一句话中汉字（包含数字等）和标点符号的个数。

sentence = input("请输入一句中文句子：")
num_chinese = 0 # 汉字个数
num_punctuation = 0 # 标点符号个数
for char in sentence:
if char.isnumeric() or char.isalpha():
num_chinese += 1
elif char.isspace():
continue
else:
num_punctuation += 1
print("汉字个数为：", num_chinese)
print("标点符号个数为：", num_punctuation)
