当我编译下面的Python代码时,我得到了

IndentationError:unindent与任何外部缩进级别都不匹配

import sys

def Factorial(n): # Return factorial
    result = 1
    for i in range (1,n):
        result = result * i
    print "factorial is ",result
    return result

为什么？

运行时不断告诉我:

期望一个缩进的块

但是我不希望在我的except块中没有写任何内容,我只是希望它能够捕获并吞下异常.

我有一个Python脚本:

if True:
    if False:
        print('foo')
   print('bar')

但是,当我尝试运行我的脚本时,Python提出了一个IndentationError:

  File "script.py", line 4
    print('bar')
               ^
IndentationError: unindent does not match any outer indentation level

我一直在玩我的程序,我还能够产生其他三个错误:

• IndentationError: unexpected indent
• IndentationError: expected an indented block
• TabError: inconsistent use of tabs and spaces in indentation

这些错误意味着什么？我究竟做错了什么？我该如何修复我的代码？

我无法理解为什么python会出现"预期的缩进块"错误？

""" This module prints all the items within a list"""
def print_lol(the_list):
""" The following for loop iterates over every item in the list and checks whether
the list item is another list or not. in case the list item is another list it recalls the function else it prints the ist item"""

    for each_item in the_list:
        if isinstance(each_item, list):
            print_lol(each_item)
        else:
            print(each_item)

这是代码:

def myfirst_yoursecond(p,q):

a = p.find(" ")
b = q.find(" ")
str_p = p[0:a]
str_q = p[b+1:]

if str_p == str_q:
    result = True
else:
    result = False
return result

这是错误:

Traceback (most recent call last):
File "vm_main.py", line 26, in <module>
import main
File "/tmp/vmuser_ssgopfskde/main.py", line 22
result = False
^
IndentationError: expected an indented block

我的代码出了什么问题？
