计算两个字符串中的字符数的问题

def count_characters(str1, str2):
    count1 = {}
    count2 = {}

    # 统计第一个字符串中每个字符的出现次数
    for char in str1:
        count1[char] = count1.get(char, 0) + 1

    # 统计第二个字符串中每个字符的出现次数
    for char in str2:
        count2[char] = count2.get(char, 0) + 1

    return count1, count2

str1 = "Hello, World!"
str2 = "Hello, everyone!"

count1, count2 = count_characters(str1, str2)
print("字符数统计结果:")
print("字符串1:", count1)
print("字符串2:", count2)
