如何將txt文件轉換為整數列表

Question

首先，我的txt文件數據如下：

51
2
2
49
15
2
1
14

我想將它們轉換為列表以進行進一步的計算，但是我做不到，我嘗試使用for循環逐一打印。 然后錯誤消息“屬性錯誤”不斷出現。

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()

Answer 2

編輯：錯誤的語言。

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