python编程实例 计算字符串中空格、英文、数字、其它字符的数量 两种方式实现

#字符串构成，统计出字符串中
#空格 英文字符 数字 其它字符的数量
'''使用自带函数
a=input("请输入：")
kong=0
ying=0
shu=0
qita=0
for i in range(len(a)):
    if(a[i].isspace()):
        kong+=1
    elif(a[i].isdigit()):
        shu+=1
    elif(a[i].isalpha()):
        ying+=1
    else:
        qita+=1
print("空格：",str(kong),"数字：",str(shu),"英文：",str(ying),"其它：",str(qita))

#使用ascii码
