python - 从字符串到元组的转换 - 双逗号

Question

我想从文件中读取行并打印元组列表中的内容。
但我在转换过程中得到了两个逗号。
我无法找到删除逗号的方法。

代码:

def arrivalsFile(file_name):
    """
    Reads part of an input file with the arrivals into a list of flights.
    Requires: file_name, for arrivals, is a text file with the structure indicated in the quizz
    Ensures: list of tuples, each corresponding to one flight

    >>> arrivalsFile("arrivals_14_16.txt")
    [('KLM75', 'Amsterdam', '14:35', '60', '50'), ('AF111', 'Paris', '14:20', '50', '64'),       ('LH333', 'Frankfurt', '14:10', '112', '203'), ('KLM71', 'Madrid', '14:55', '120', '100'), ('TAP103', 'Salvador', '15:20', '174', '210'), ('LH123', 'Berlin', '15:10', '115', '210')]
    """
    lista = []
    inFile = open(file_name, "r")
    for line in inFile:
        if "Arrivals:" in line:
            for line in inFile:
                lista.append(tuple(line.split()))
    inFile.close()

执行:

Answer 1

lista.append(tuple(line.split(",")))

用,分割，而不是空格。
