以下是代码：

我不熟悉使用Python并试图解决这个问题，但不幸的是，我无法解决。希望这里有人能帮助我。

Here is the code:
I am new to using Python and tried to fix the issue, but unfortunately, I wasn't able to. Hopefully someone here can help me.

#!/usr/bin/env python
# This program exmamines variables x, y, and z 
# and prints the largest odd number among them

import sys

x,y,z = map(int,sys.argv[1:4])

if x%2 != 0:
  if y%2 != 0:
    if z%2 != 0:
      if x > y and x > z: #x is the biggest odd
        print 'x is the biggest odd ' and x
      elif y > z and y > x: #y is the biggest odd
        print 'y is the biggest odd ' and y
      elif z > x and z > y: #z is the biggest odd
        print 'z is the biggest odd ' and z

    else: #z is even
      if x > y: #x is the biggest odd
        print 'x is the biggest odd ' and x
      else: #y is the biggest odd
        print 'y is the biggest odd ' and y

  else: #y is even
      if z%2 != 0: #z is odd
        if x > z: #x is the biggest odd
          print 'x is the biggest odd ' and x
        else: #z is the biggest odd
          print 'z is the biggest odd ' and z
      else: #y,z are even and x is the biggest odd
        print 'x is the biggest odd ' and x

else: #x is even
  if y%2 != 0 and z%2 != 0: #y,z is odd
      if y > z: #y is the biggest odd
        print 'y is the biggest odd ' and y
      else: #z is the biggest odd
        print 'z is the biggest odd ' and z
  else: #x and y are even
    if z%2 != 0: #z is the biggest odd
      print 'z is the biggest odd ' and z
  else: #x and z are even
    if y%2 != 0: #y is odd
      if z%2 = 0: #z is even
        print 'y is the biggest odd ' and y

print 'finished'

推荐答案

缩进是错误的;注意

  else: #x and y are even
    if z%2 != 0: #z is the biggest odd
      print 'z is the biggest odd ' and z
  else: #x and z are even

你想缩进第二个 else 以及它下面的所有内容。您可能需要运行 pep8 来验证一切都井井有条，即你使用正确的间距，不要混合标签和空格字符。

You want to indent the second else and everything below it. You may want to run pep8 to verify that everything is in order, i.e. that you're using correct spacing and don't mix tabs and space characters.

此外，在行

if z%2 = 0: #z is even

您想要比较 == ，而不是作业 = 。

you want the comparison ==, not the assignment =.
