为什么我下面的程序运行总是报错呀，
newman0708@newman0708-desktop:~/doc/python$ ./fig07_02.py
from: can't read /var/mail/myClock
./fig07_02.py: line 6: syntax error near unexpected token `('
./fig07_02.py: line 6: `time1=Time() #create object of class Time'
应该 怎么改呀，请各位指点一下，谢谢
#Fig.7.1: myClock.py
#Simple definition of class Time.
class Time:
"""Time abstract data type (ADT) definition"""
def __init__(self):
"""initialize hour,minute and second to zero"""
self.hour=0
self.minute=0
self.second=0
def printMilitary(self):
"""Prints object of class Time in military format """
print"%.2d:%.2d:%.2d" %
(self.hour,self.minite,self.second),
def printStandard(self):
"""Prints object of class Time in standard format"""
standardTime=""
if self.hour==0 or self.hour==12:
standardTime+="12:"
else:
standardTime+="%d:" %(self.hour % 12)
standardTime+="%.2d:%.2d" % (self.minute,self.second)
if self.hour<12:
standardTime+=" AM"
else:
standardTime+=" PM"
print standardTime,
#Fig. 7.2 : fig07_02.py

#access object's attributes
print "Time attributes of time1 are:"
