print(f"{str1}中的英文字母个数为：{alpha}")
print(f"{str1}中的空格个数为：{ space}")

题目中百分号不会写，求各位帮我一下

 
s = input()
t_num = 0
w_num = 0
s_num = 0
o_num = 0
for t in s:
    if t.isdigit():
        t_num += 1
    elif t.isalpha():
        w_num += 1
    elif t == ' ':
        s_num += 1
    else:
        o_num += 1
 
print('统计如下：')
print('数字有{}个，占{}%'.format(t_num, round(t_num/len(s), 2) * 100))
print('字母有{}个，占{}%'.format(w_num, round(w_num/len(s), 2) * 100))
print('空格有{}个，占{}%'.format(s_num, round(s_num/len(s), 2) * 100))
print('其他有{}个，占{}%'.format(o_num, round(o_num/len(s), 2) * 100))
