我正在学习HeadFirst Python书籍中的教程。在第7章中,我在尝试运行下一个代码时收到一条错误消息:
运动员级别:
class AthleteList(list):
def __init__(self, a_name, a_dob=None, a_times=[]):
list.__init__([])
self.name = a_name
self.dob = a_dob
self.extend(a_times)
def top3(self):
return(sorted(set([sanitize(t) for t in self]))[0:3])
def get_coach_data(filename):
try:
with open(filename) as f:
data = f.readline()
templ = data.strip().split(',')
return(AthleteList(templ.pop(0), templ.pop(0), templ))
except IOError as ioerr:
print('File error: ' + str(ioerr))
return(None)
def sanitize(time_string):
if '-' in time_string:
splitter = '-'
elif ':' in time_string:
splitter = ':'
else:
return(time_string)
(mins, secs) = time_string.split(splitter)
return(mins + '.' + secs)
在下一个模块中,我做了一些测试:
import pickle
import AthleteList
def get_coach_data(filename):
try:
with open(filename) as f:
data = f.readline()
templ = data.strip().split(',')
return(AthleteList(templ.pop(0), templ.pop(0), templ))
except IOError as ioerr:
print('File error (get_coach_data): ' + str(ioerr))
return(None)
def put_to_store(files_list):
all_athletes = {}
for each_file in files_list:
ath = get_coach_data(each_file)
all_athletes[ath.name] = ath
try:
with open('athletes.pickle', 'wb') as athf:
pickle.dump(all_athletes, athf)
except IOError as ioerr:
print('File error (put_and_store): ' + str(ioerr))
return(all_athletes)
def get_from_store():
all_athletes = {}
try:
with open('athletes.pickle', 'rb') as athf:
all_athletes = pickle.load(athf)
except IOError as ioerr:
print('File error (get_from_store): ' + str(ioerr))
return(all_athletes)
print (dir())
the_files = ['sarah.txt','james.txt','mikey.txt','julie.txt']
data = put_to_store(the_files)
data
这是Julie.txt文件的内容:
Julie Jones,2002-8-17,2.59,2.11,2:11,2:23,3-10,2-23,3:10,3.21,3-21,3.01,3.02,2:59
其他文件也差不多
我应该得到这样的输出:
{'James Lee': ['2-34', '3:21', '2.34', '2.45', '3.01', '2:01', '2:01', '3:10', '2-22', '2-
01', '2.01', '2:16'], 'Sarah Sweeney': ['2:58', '2.58', '2:39', '2-25', '2-55', '2:54', '2.18',
'2:55', '2:55', '2:22', '2-21', '2.22'], 'Julie Jones': ['2.59', '2.11', '2:11', '2:23', '3-
10', '2-23', '3:10', '3.21', '3-21', '3.01', '3.02', '2:59'], 'Mikey McManus': ['2:22', '3.01',
'3:01', '3.02', '3:02', '3.02', '3:22', '2.49', '2:38', '2:40', '2.22', '2-31']}
但我收到一条错误信息:
['AthleteList', '__builtins__', '__cached__', '__doc__', '__file__', '__name__', '__package__', 'get_coach_data', 'get_from_store', 'pickle', 'put_to_store']
Traceback (most recent call last):

ath = get_coach_data(each_file)
File "C:\Python\workspace\HeadFirst\src\prueba.py", line 11, in get_coach_data
return(AthleteList(templ.pop(0), templ.pop(0), templ))
TypeError: 'module' object is not callable
我做错什么了?
正如@Agam所说
在驱动程序文件中需要此语句:
from AthleteList import AtheleteList
您的模块和类
AthleteList
具有相同的名称。更改:致:
这意味着您正在导入module对象,并且将无法访问您在
AthleteList
中拥有的任何module方法您的模块和类
AthleteList
具有相同的名称。线路导入模块并在当前作用域中创建指向模块对象的名称
AthleteList
。如果要访问实际的类,请使用尤其是在排队的时候
实际上,您访问的是模块对象,而不是类。试试看
