"""

存在一一个名称为data.log的文件，data.log中 的内容是以逗号作为分隔符的，依次存储了一次测试的
TestID,TestTime. ,Success(0成功; 1失败)。 文件中数据均为非负整数。请写一段程序(不限语言)， 对所有成功
(Success=0)的测试，输出:
1)打印最大、最小TestTime;
2)打印平均TestTime,保留小数点2位数。
data.log的内容格式如下:
TestID ,TestTime ,Success
0,149,0
1,69,0
2,45,0
3,18,1
4,18,1

方法一：

data_list=[]
with open( '/Users/momoon/Downloads/data.log' , mode='r' , encoding= 'utf-8') as f:
    for line in f.readlines( ):
        line_list = line.split(',')
        data_list.append(line_list)
test_time = []
for i in data_list[1:]:
    test_time.append(int(i[1]))
len = len(test_time)
print(data_list)
print(test_time)
avg = sum(test_time)/len

# 冒泡排序法
for n in range(0,len-1):
    for j in range(n+1 ,len):
        if test_time[j] <test_time[n]:
            temp = test_time[n]
            test_time[n] = test_time[j]
            test_time[j] = temp
print("{} ,{}".format(test_time[-1],test_time[0]))
print("TtTestTime: %.2f" %avg)

"""
输出结果：

[['TestID', 'TestTime ', 'Success '], ['0', '149', '0 '], ['1 ', '69', '0 '], ['2', '45', '0 '], ['3', '18', '1 '], ['4', '18', '1']]

方法二：

    with open(os.getcwd() + "/data.log") as fs:
