从文本文件中删除或清除行

您可以以读写模式打开文件并删除符合条件的行。

with open(file_path, "r+") as fp:
    lines = fp.readlines()
    fp.seek(0)
    for line in lines:
        if "boop" not in line:
            fp.write(line)
    fp.truncate()

这个 seek

参考: using Python for deleting a specific line in a file

path='path/to/file.txt'
with open(path, "r") as f:
    lines = f.readlines()
    with open(path, "w") as f:
        for line in lines:
            if line.strip("\n") != "boop":
                f.write(line)
