在《python scripting for computational science》里看到的这样的用法,这是字
典还是?
---
# data
compiler_data['GNU']['type'] = 'GNU 3.0'
compiler_data['GNU']['name'] = 'g77'
compiler_data['GNU']['options'] = '-Wall'
compiler_data['GNU']['libs'] = '-lf2c'
compiler_data['GNU']['test'] = '-Wall'
compiler_data['GNU']['flags'] = ('-O1','-O3','-O3 -funroll-loops')

for compiler in compiler_data:
c = compiler_data[compiler] # 'GNU', 'Sun', etc.
cmd = ' '.join([c['name'], c['options'], c['libs']])
for flag in c[flags]:
os.system(' '.join([cmd, flag, ' -o app ', files]))

这是字典的用法呀。现在可以使用：
for i in d:
这种用法来遍历字典d的键值。有兴趣你自已可以试一试。

sorry, 我意思是说前面的compiler_data部分

--------------------------------------------------------------------
# data
compiler_data['GNU']['type'] = 'GNU 3.0'
compiler_data['GNU']['name'] = 'g77'
compiler_data['GNU']['options'] = '-Wall'
compiler_data['GNU']['libs'] = '-lf2c'
compiler_data['GNU']['test'] = '-Wall'
compiler_data['GNU']['flags'] = ('-O1','-O3','-O3 -funroll-loops')
--------------------------------------------------------------------

在python2.3.4里面不能运行。 

字典不是类似 dict1={a:b,c:d,e:f} 这样定义的吗?

字典是这样定义没错，但是字典的值可以还是一个字典呀，如：
a={}
a['GNU']={}
这样就可以：
a['GNU']['options'] = '-Wall'了
a['GNU']还可以写成一个对象，这个对象有__setitem__方法，可以用来摸拟a['item']这样的操作。方法很多的。

compiler_data = {'GNU':{ }}
compiler_data['GNU']['type'] = 'GNU 3.0'
......


compiler_data['GNU']也是一个字典，所以可以这样用。

谢谢，字典可以多重嵌套呀，很方便。
