蟒蛇相当于PHP的文件（fn，FILE_IGNORE_NEW_LINES）

Question

我想在python中读取一个文件并将每个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，但我如何在Python中执行此操作？

Answer 1

当读取文件（逐行）时，通常将新行字符附加到行的末尾，然后循环播放它。如果你想摆脱它们？

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

你想要这个：

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