用python统计文本字符出现的次数

试了试Pi，1000000位数，个数字的统计。

def load_data(path):
    ret = ""#[]
    for line in open (path,"r",encoding = "utf-8"):
        ret += line.strip()
        return ret
 
def statistic(strings):
    t_char2cnt = {}
    for char in strings:
        if char not in t_char2cnt:
            t_char2cnt[char] = 1
        else:
            t_char2cnt[char] +=1
    return t_char2cnt
 
 
if __name__=="__main__":
    path = "c:\\1.txt"
    strings = load_data(path)
    t_char2cnt = statistic(strings)
    print(t_char2cnt)
 

结果如下：

'3': 100233,  '1': 99762, '4': 100232, '5': 100364, '9': 100108, '2': 100032, '6': 99549, '8': 99990, '7': 99804, '0': 99970
