如何将txt文件转换为整数列表

Question

首先，我的txt文件数据如下：

51
2
2
49
15
2
1
14

我想将它们转换为列表以进行进一步的计算，但我无法做到这一点，我尝试使用for循环逐个打印它。然后是错误消息＆＃34;属性错误＆＃34;不断出现。

def main():
    file = str(input("Please enter the full name of the desired file(with extension) at the prompt below: \n"))
    print (get_value(file))

def get_value(file):

    file_open = open(file,"r")
    print (file_open.read())
    a = len(file)
    print ("Length =",a)
    for line in range file_open:
        print (line)

main()

Answer 1

def main():
    file = str(input("Please enter the full name of the desired file(with extension) at the prompt below: \n"))
    print (get_value(file))

def get_value(file):

    file_open = open(file,"r")
    lsLines = file_open.readlines()
    lsLines = [int(x) for x in lsLines if len(x.strip()) > 0]
    file_open.close()

    return lsLines

main()

编辑：错误的语言。

with open("file.txt") as f:
    ints = [int(line) in f.readlines()]
