Python 相当于 PHP 的文件(fn， FILE_IGNORE_NEW_LINES)

Question

我想在python中读取一个文件，并将每一行新行放入一个数组中。我知道如何在PHP中使用file(fn, FILE_IGNORE_NEW_LINES);函数和它的FILE_IGNORE_NEW_LINES参数来实现它，但我如何在Python中实现它？

Answer 1

读取文件（逐行）时，通常在循环文件时，换行符会附加到行的末尾。如果你想去掉它们？

with open('filename.txt', 'r') as f:
    for line in f:
        line = line.strip('n')
        #do things with the stripped line!

Answer 2

这与（在Python中）相同：

with open("file.txt", "r") as f:
    for line in f:
        line = line.rstrip("n")
        ...

Answer 3

您想要的是：

with open('filename.txt', 'r') as f:
    data = [line.replace('n', '') for line in f]
