Else 的语法无效：3.8

Question

我是 python 脚本的新手，想知道如何修复下面的代码。我想知道如何解决Invalid Syntax of Else语句，谢谢！

import os
import zipfile

f = open("filelist.txt","w+")
path=("pathtofile")
directory=os.fsencode(path)
filenames = []
for file in os.listdir(directory):
    filename = os.fsdecode(file)
    if filename.endswith(".zip"):
        with zipfile.ZipFile(filename, 'r') as zipObj:
            contents = zipObj.namelist()

    listfile = (str(contents))
    remchar = "'[]"
    for char in remchar:
            a = listfile.replace(char,"")
    f.write (a)
    continue
    else:
        pass

    f.close()

Answer 1

请记住 python 中的缩进很重要。您的 else: 语句在同一级别上没有匹配的 if 语句。确保正确缩进以实现您要查找的内容：

if filename.endswith(".zip"):
    with zipfile.ZipFile(filename, 'r') as zipObj:
        contents = zipObj.namelist()

        listfile = (str(contents))
        remchar = "'[]"
        for char in remchar:
            a = listfile.replace(char,"")
            f.write (a)
        continue
else:
    pass

Answer 2

else 语句在 if 语句的末尾之外。您必须在结束另一个后立即包含一个 else。是这样的：

if filename.endswith(".zip"):
    with zipfile.ZipFile(filename, 'r') as zipObj:
        contents = zipObj.namelist()
else:
    pass

如果只写pass，那么可以直接省略else。
