Python中计算字符串中字母的次数

已知字符串str1= 'skdaskerkjsalkj',请统计该字符串中各字母出现的次数。

def count_char(str):
    dict_char = {}
    for i in str:
        if i not in dict_char:
            dict_char[i] = 1
        else:
            dict_char[i] += 1
    return dict_char

if __name__ == "__main__":
    str1= 'skdaskerkjsalkj'
    print(count_char(str1))
