获得pyc文件的magic数字和创建时间

 1 import struct
 2 import time
 3 import marshal
 4 file = open(file_name,'rb')
 5 str_magic = file.read(4)
 6     str_time = file.read(4)
 7     code = marshal.load(file)
 8     file.close()
 9     
10     pyc_magic   = struct.unpack('i',str_magic)[0] & (~0xffff0000)
11     pyc_time    = time.ctime(struct.unpack('i',str_time)[0])
12     print pyc_magic,pyc_time
