您可以以讀寫模式打開文件并刪除符合條件的行。
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()
seek重置文件指針。

打開文件并讀取其內(nèi)容，然后再次打開文件，將行寫入其中但不要包含“boop”的行：
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)
