Python 3.x Python:从文件中获取输入并将其存储为int数据类型,python-3.x,input,file-handling,Python 3.x,Input,File Handling,我有一个输入文件“input.dat”: 08 02 22 97 38 15 00 40 00 75 04 05 07 78 52 12 50 77 91 08 49 49 99 40 17 81 18 57 60 87 17 40 98 43 69 48 04 56 62 00 81 49 31 73 55 79 14 29 93 71 40 67 53 88 30 03 49 13 36 65 52 70 95 23 04 60 11 42 69 24 68 56 01 32 56 71 3

我将数据存储在2D数组中,并尝试按照给定代码进行处理:

if __name__ == "__main__":
    dataFile = open("/Users/atulyaratanjha/Documents/Python/P11.dat")
    arr = []
    for line in dataFile:
        arr.append(line.split())
    maxMult = 0
    for i in range(16):
        for j in range(20):
            mult = arr[i][j] * arr[i+1][j] * arr[i+2][j] * arr[i+3][j]
            maxMult = max(maxMult, mult)
    for i in range(20):
        for j in range(16):
            mult = arr[i][j] * arr[i][j+1] * arr[i][j+2] * arr[i][j+3]
            maxMult = max(maxMult, mult)
    for i in range(16):
        for j in range(16):
            mult = arr[i][j] * arr[i+1][j+1] * arr[i+2][j+2] * arr[i+2][j+3]
            maxMult = max(maxMult, mult)
    print(maxMult)
它给出了以下错误:

TypeError: can't multiply sequence by non-int of type 'str'

我知道我可以通过运行for循环将数据从'str'更改为'int',但是有没有办法在输入阶段将数据存储为'int'
将arr.append(line.split())更改为arr.append(list(map(int,line.split()))应该可以工作。

arr.append(line.split())
更改为
arr.append(list(map(int,line.split())
应该可以工作。谢谢,它工作了!!!
