Python无缘无故地给出“IndentationError”

Question

我有一个简短的代码片段，它不起作用，并不断给我这个错误：

我在我的代码里没有发现任何错误。。。我已经检查过了，没有可能导致此错误的无效ASCII字符。你知道吗

#!/usr/bin/env python

def posts(data):

    postdata = ""

    for char in data:
        # If it's a non-escaped {, then it's the beginning of a post.
        if char == "{":
            insidepost = True
            # Skip to the char after {, start copying from there
            continue
        # If it's a non-escaped }, yield the post, and clean the buffer.
        if char == "}":
            insidepost = False
            yield postdata.replace("&lc;","{").replace("&rc;","}")
            postdata = ""
        # While in a post, copy the data into the post buffer.
        if insidepost:
            postdata += char

def findtags(data):
    tagdata = ""
    for char in data: *[This is the line which causes the error]*
        if char == "[":
            insidetag = True
            continue
        if char == "]":
            insidetag = False
            yield postdata
            postdata = ""
        if insidepost:
            postdata += char


f = """{A}{B}{c}{dDD}"""
for f in posts(f): print f

有人知道怎么解决这个问题吗？非常感谢。你知道吗

Answer 1

检查是否存在卡舌。例如：在vim的正常模式下，输入：/\t

Answer 2

你把制表符和空格混在一起了，这是不应该的。因为PEP 8 Style Guide空格的使用多于制表符，所以请尝试使用空格：D
