在我之前的帖子中从 phihag 那里得到所需的帮助后，我注意到我没有得到所有偶数的结果。但是，我在第 47 行使用 else 时不断收到语法错误。
else: # x, y, and z are even
可能是什么问题？
#!/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 ', x
elif y > z and y > x: # y is the biggest odd
print 'y is the biggest odd ', y
elif z > x and z > y: # z is the biggest odd
print 'z is the biggest odd ', z
else: # z is even
if x > y: # x is the biggest odd
print 'x is the biggest odd ', x
else: # y is the biggest odd
print 'y is the biggest odd ', y
else: # y is even
if z % 2 != 0: # z is odd

print 'x is the biggest odd ', x

print 'x, y, and z are even.'
print 'finished'
