在Python中操作字典之fromkeys()方法的使用

dict.fromkeys(seq[, value]))

#!/usr/bin/python

seq = ('name', 'age', 'sex')

dict = dict.fromkeys(seq)
print "New Dictionary : %s" % str(dict)

dict = dict.fromkeys(seq, 10)
print "New Dictionary : %s" % str(dict)

New Dictionary : {'age': None, 'name': None, 'sex': None}
New Dictionary : {'age': 10, 'name': 10, 'sex': 10}
