PYTHON 2.7.3中的布尔运算符

我正在编写一个程序，需要向用户请求输入。我希望Python检查输入是否为数字（而不是单词或标点符号...），并且是否是表示我的元组中对象的数字。如果这3个条件中的任何一个结果为False，那么我希望用户为该变量提供另一个值。以下是我的代码：\n

colour={'yello':1, 'blue':2, 'red':3, 'black': 4, 'white': 5, 'green': 6}
height_measurements=('centimeter:1', 'inch:2', 'meter:3', 'foot:4')
weight_measurements=('gram:1', 'kilogram:2', 'pounds:3')
print height_measurements
hm_choice = raw_input('choose your height measurement').lower()
while not hm_choice.isdigit() or hm_choice > 0 or hm_choice < len(height_measurements) :
    hm_choice = raw_input('choose your height measurement').lower()        
print weight_measurements
wm_choice = raw_input('choose your weight measurement').lower()
while not wm_choice.isdigit() or wm_choice > 0 or wm_choce < len(weight_measurements) :
    wm_choice = raw_input('choose your weight measurement').lower()

\n当我测试时，无论我输入什么内容，它都会不断地要求我插入height_measurement的输入。请检查我的代码并为我进行更正。如果方便的话，请给我提供你的更好的代码。\n注意：在下面提供的更好的代码中，我已经修正了一些拼写错误和逻辑错误。\n

colour = {'yellow': 1, 'blue': 2, 'red': 3, 'black': 4, 'white': 5, 'green': 6}
height_measurements = ('centimeter:1', 'inch:2', 'meter:3', 'foot:4')
weight_measurements = ('gram:1', 'kilogram:2', 'pounds:3')
print(height_measurements)
hm_choice = input('choose your height measurement: ').lower()
while not (hm_choice.isdigit() and int(hm_choice) > 0 and int(hm_choice) <= len(height_measurements)):
    hm_choice = input('choose your height measurement: ').lower()
print(weight_measurements)
wm_choice = input('choose your weight measurement: ').lower()
while not (wm_choice.isdigit() and int(wm_choice) > 0 and int(wm_choice) <= len(weight_measurements)):
    wm_choice = input('choose your weight measurement: ').lower()

\n在这个改进的代码中，我修正了以下问题：\n1. 将`yello`更正为`yellow`，以使其与字典`colour`中的键匹配。\n2. 将`raw_input`更正为`input`，因为在Python 3中，`raw_input`已被`input`取代。\n3. 将`hm_choce`更正为`hm_choice`，以修复拼写错误。\n4. 在`while`循环中，我更正了逻辑错误，以确保`hm_choice`和`wm_choice`是数字，并且在有效范围内。
