检查下面的代码，找出错误并修改 from csv import reader with open("C:\\Users\\pc\\Desktop\\nanjing_weather.csv","r")as csv_file: csv_reader=reader(csv_file) list_of_rows=list(csv_reader) data=[item[0] for item in list_of_rows] high=[item[1] for item in list_of_rows] high=list(map(int,high)) print("5-7月份南京最高温最大值为{}℃".format(max(high)) print("其对应日期为:") for i in range(0,len(high)): if high[i]==max(high): print(data[i]) low=[item[2] for item in list_of_rows] low=list(map(int,low)) print("\n5-7月份南京最低温最小值为{}℃".format(min(low)) print("其对应的日期为:") for i in range(0,len(low)): if low[i]==min(low): print(data[i]) dif=[int(item[1])-int(item[2]) for item in list_of_rows dif=list(map(int,dif)) print("5-7月份南京最大温差最大值为{}℃".format(max(dif))) print("其对应日期为:") for i in range(0,len(dif)): if dif[i]==max(dif): print(data[i])

以下是修改后的代码：

from csv import reader

with open("C:\\Users\\pc\\Desktop\\nanjing_weather.csv","r") as csv_file:
    csv_reader = reader(csv_file)
    list_of_rows = list(csv_reader)
    data = [item[0] for item in list_of_rows]
    high = [item[1] for item in list_of_rows]
    high = list(map(int, high))
    print("5-7月份南京最高温最大值为{}℃".format(max(high)))
    print("其对应日期为:")
    for i in range(0, len(high)):
        if high[i] == max(high):
            print(data[i])

    low = [item[2] for item in list_of_rows]
    low = list(map(int, low))
    print("\n5-7月份南京最低温最小值为{}℃".format(min(low)))
    print("其对应的日期为:")
    for i in range(0, len(low)):
        if low[i] == min(low):
            print(data[i])

    dif = [int(item[1]) - int(item[2]) for item in list_of_rows]
    dif = list(map(int, dif))
    print("5-7月份南京最大温差最大值为{}℃".format(max(dif)))
    print("其对应日期为:")
    for i in range(0, len(dif)):
        if dif[i] == max(dif):
            print(data[i]))

首先，第一个问题是缺少了三个括号。在第11行，`print("5-7月份南京最高温最大值为{}℃".format(max(high))` 应该修改为 `print("5-7月份南京最高温最大值为{}℃".format(max(high)))`，即在最后添加三个括号。

第二个问题是缺少了一个空格。在第16行，`low=[item[2] for item in list_of_rows] low=list(map(int,low))` 应该修改为 `low=[item[2] for item in list_of_rows] low=list(map(int,low))`，即在第二行末尾添加一个空格。

第三个问题是缺少了一个右方括号。在第28行，`if dif[i]==max(dif): print(data[i])` 应该修改为 `if dif[i]==max(dif): print(data[i])`，即在最后添加一个右方括号。
