Python循环语法错误？

Question

为什么这不会编译......我很难过......

for files in glob.glob("*.txt"):
    f=open(files)
    for lines in f:
        print lines

我明白了:

File "teleparse.py", line 21
for lines in f:
^
IndentationError: unexpected indent

Answer 1

"不,我确保缩进只包含标签."

你错了:

>>> s = """
... 
...     for files in glob.glob("*.txt"):
...         f=open(files)
...         for lines in f:
...                 print lines
... """
>>> 
>>> for line in s.splitlines():
...     print repr(line)
... 
''
''
'    for files in glob.glob("*.txt"):'
'        f=open(files)'
'\t    for lines in f:'
'\t\t    print lines'

您可以python -tt yourprogramname.py用来确认您正在混合制表符和空格.
