Python - 工作2.7但2.6上的错误

Question

我正在开发一个关于Django的webapp，但我在Python 2.6.6版本上遇到错误，但它在2.7上工作正常

def check(attribute):
   global rates
   if (attribute.temperature_value < rates[0] or 
       attribute.temperature_value > rates[1] or 
       attribute.heartbeat_value<rates[2] or 
       attribute.heartbeat_value>rates[3]):
      return True
   else:
      return False

Django调试器显示存在语法错误。

此外，如果我尝试删除该功能，我会在另一行说出另一个错误

EOL while scanning string literal (views.py, line 109)

在109行：

data = \
  DataPool(
    series=
    [{'options': {
     'source': values},
       'terms': [
        'current_time',
        'temperature_value',
        'heartbeat_value']}
    ])

谢谢你的帮助。

Answer 1

我会这样写：

def check(attr):
    temp, pulse = attr.temperature_value, attr.heartbeat_value
    def check_range(value, low, high):
        return value < low or value > high
    return check_range(temp, rates[0], rates[1]) or \
        check_range(pulse, rates[2], rates[3])

但是，只有尾随反斜杠才能解决您的问题。

不确定你的其他问题是什么。 这很好用：

class DataPool(object):
    def __init__(self, series):
        self.series = series

values = list(range(5))

data = \
  DataPool(
    series=
    [{'options': {
     'source': values},
       'terms': [
        'current_time',
        'temperature_value',
        'heartbeat_value']}
    ])

BTW，这段代码：

def check_range(value, low, high):
    return value < low or value > high

也可能是：

def check_range(value, low, high):
    return not (low <= value <= high)
