python - 删除括号内包含的文本

Question

我正在尝试编写一个清理文本文件的程序；具体来说，我正在尝试清理莎士比亚的《仲夏夜之梦》的副本。我正在尝试编写一个代码来消除脚本中的舞台方向，以便此文本:

THESEUS Go, bid the huntsmen wake them with their horns.

[Horns, and shout within. DEMETRIUS, LYSANDER,HERMIA, and HELENA awake

and start up.]

Good-morrow, friends. Saint Valentine is past; Begin these wood-birds but to couple now?

LYSANDER Pardon, my lord.

[He and the rest kneel to THESEUS.]

THESEUS

I pray you all, stand up. I know you two are rival enemies; How comes this gentle concord in the world, That hatred is so far from jealousy To sleep by hate, and fear no enmity?

变成这样的文字:

THESEUS Go, bid the huntsmen wake them with their horns.

Good-morrow, friends. Saint Valentine is past; Begin these wood-birds but to couple now?

LYSANDER Pardon, my lord.

THESEUS

I pray you all, stand up. I know you two are rival enemies; How comes this gentle concord in the world, That hatred is so far from jealousy To sleep by hate, and fear no enmity?

这是我编写的代码，但它在我假设的 while 循环上被挂起。任何帮助将不胜感激!

def cleanDirections(inFilename, outFilename):
    inFile = open(inFilename, "r")
    outFile = open(outFilename, "w")

    line = inFile.readline()

    while line != "":

        if line.startswith("[") == True:
            if line.endswith("]") == True:
                line = inFile.readline()
            else:
                while line.endswith("]") == False:
                    line = inFile.readline()
            line = inFile.readline()

        else:
            outFile.write(line)
            line = inFile.readline()

另外:如果可以用这种语法提供帮助，那就太好了。我还在学习中，所以我还不知道更高级的Python。

由于您的括号跨越多行，因此您无法逐行执行此操作。使用:

text = inFile.readLines()
text = re.sub("\[[^\]]*\]","",text) #will kill any [STUFF]
