Python字典练习题：统计列表中字符出现的次数

题目：统计例如一个列表[“c”, “d”, “a”, “a”, “d”, “a”]中每个字符元素出现的次数

示例代码：

chars = ["a", "c", "d", "a", "c", "a"]
char_count = {}
for char in chars:
    if char in char_count:
        char_count[char] += 1
    else:
        char_count[char] = 1
print(char_count)

运行结果：

{‘a’: 3, ‘c’: 2, ‘d’: 1}
